For the Love of Trees

Fall is the perfect season to celebrate the beauty of trees. Color-changing, wind-buffering, rainwater-absorbing, trees tend to take center stage at autumnal time. Hope College sophomore Katelyn DeWitt, however, appreciates their value all year round. And she doesn’t mind being called a tree hugger because of it.

Actually, that is exactly what DeWitt did for ten weeks during the summer of 2018. She embraced her work with trees while inventorying and measuring the trunk diameters of nearly half of the tree population (so far 3500+) found on public property in the City of Holland. In doing so, she dug into determining the environmental and monetary values of various species in the city’s urban canopy.

What she found is confirmation, and then some, of Joyce Kilmer’s famous “Trees” poem. There is indeed nothing lovelier than a tree when it comes to the myriad of environmental benefits it provides in addition to its aesthetic value. Drought and flood mitigation, climate stability through carbon sequestration, pollution filtration, noise reduction and wildlife habitation are all the ecological workings of a tree. Natural benefits aside, the so-far-surveyed trees in Holland are projected to provide more than $16,166 in environmental value annually, according to DeWitt’s preliminary calculations that do not factor in electricity offset yet.

DeWitt took on the collaboratively- funded project (by the City of Holland, Hope College Biology Department and the Holland-Hope College Sustainability Institute) simply because “I’ve always liked trees,” says the biology major, “and I think it’s important to know more about them to help the world we live in.” Directed in her efforts by Dr. Kathy Winnett-Murray and Dr. Greg Murray, professors of biology, and Michelle Gibbs, director of the HHCSI, DeWitt spent her days identifying and measuring the diameters of 3,663 trees at a consistent height of 1.37 meters, also known as diameter at breast height (dbh), the universal standard to measure trees in field studies.

“From that (dbh) you can infer a number of things about how much the tree is absorbing carbon, or how much it is offsetting energy costs,” says Winnett-Murray. All of those tree-benefit computations are calculated by iTree, a software program developed by the U.S. Forest Service, and used from coast to coast for forestry studies. DeWitt used iTree to determine the $16,166 in public tree value mentioned earlier.

Near Hope’s campus, DeWitt’s favorite tree is the American elm found in front of Dimnent Memorial Chapel on the right of way of College Avenue. From past studies of that tree, DeWitt estimates that it is approximately 190 years old. From her present study of the tree using the iTree program, she also estimates that the big, old American elm removes 43.3 ounces of pollution a year, helps avoid water runoff at a rate of 92.2 square feet a year, and sequesters 81.6 pounds of carbon a year.

And that’s just one tree. In all, DeWitt found 94 species of trees on Holland’s public property, the most common being the Norway maple, a non-native tree. The second most common is the native sugar maple.

And all of those trees, especially in an urban setting, are becoming more and more important as deforestation occurs in rural areas due to a rise in development. “We’re losing natural tree canopy out there in the world because of urbanization,” explains Winnett-Murray, “so that means that urban tree canopies are becoming increasingly more important for the ecosystem services that we would have been relying on other trees to perform out in forests. In the best of all possible worlds, we’d have both. What this means to me is, in the future, people will depend even more on trees in the city for the ecosystem services like carbon sequestration.”

Both Winnett-Murray and DeWitt hope to see the Holland tree study continue to its completion next summer. The professor realizes she’s found the perfect student-researcher for the project and the student appreciates the opportunity. “One of Katelyn’s characteristics that really fit this project well is that she is pretty relentless,” says Winnett-Murray. “If she came across tree she did not know already — and wow, did she know a lot of them before she started — she would not give up and just say it was an unknown. She had to find out what it was and she would not give up.”

Through it all, the future ecologist not-surprisingly says her knowledge of tree species increased as did her deep appreciation of trees’ places in every environment. “I didn’t realize how much benefit a tree can provide in actual monetary value before I started this project,” DeWitt says. “Now I also understand that a stand-alone tree in an urban forest can provide even more benefits to people than a tree in a (regular) forest does.”

Natural benefits aside, the so-far-surveyed trees in Holland are projected to provide more than $16,166 in environmental value annually, according to DeWitt’s preliminary calculations that does not factor in electricity offset yet.

Others in Holland now have the chance to learn from DeWitt’s work as well. A new Android phone app developed by Dr. Michael Jipping, professor of computer science, and two of his Hope Summer Software Institute students, helps users identify Holland trees as it accesses GPS coordinates along with the Holland tree database entered into the application. “Treesap, Bringing People to Trees” can be downloaded from Google Play, and it’s free. It’s used by “walking up to a tree on Holland public property and clicking the big red button on the interface, and it will identify the tree for you, or tell you the tree is not in the data base yet,” says Jipping. “As the database grows, more trees will be added.” Jipping also hopes to have an iPhone version of the app completed within a couple years.

As for Winnett-Murray, her goal for the app is to encourage and enable Hollanders, and visitors too, to know their trees better. “But I also hope it gets people moving around the city from place to place, helping them get outside to learn about why trees are valuable. We love the app.”

“This is the first software app I ever produced that I got a hug for,” smiles Jipping. “They are very excited because it works the way they want it to.”

Hugs for trees and software developers, in the Holland Tree Project, you can just feel the arboreal love.

To China with Hope

This past spring, for the first time in Hope’s history, not one but two May Term classes traveled to China. In “China’s Modern Growth,” students examined the nation’s economic policies and business development while touring four major cities as well as Hong Kong. In “China: Land, Wildlife and Culture,” students explored the ecosystems of China’s mountains, rivers and countryside.

Both May Term classes visited Tiananmen Square.

On the face of it, this could seem like a study-abroad city mouse and country mouse kind of story. In a way it is, but of course it would be. In Chinese cities like Beijing, Shanghai, Chengdu and Shenzhen — home to some of the world’s most famous businesses — Hope students saw firsthand what’s being done to affect the world’s second-largest economy. In the Chinese mountains of Tangjiahe Nature Preserve and lowlands of Minjiang River — home to some of the world’s most unique biodiversity — Hope students observed firsthand the likes of panda bears, takins, gingko tree forests and millennia-old irrigation systems unique to the world’s fourth-largest country.

Yet, for as divergent as these two courses’ locations were, their lessons did share one commonality: Each exposed Hope students to historical, cultural and political aspects of a country that is often at the forefront of U.S. and international conversations. Now those exchanges have stuck with them well beyond China’s borders.

That is the whole point of an international study experience: lessons learned make their way back home, get unpacked and then are used.

Andrew VandeBunte, right, and friends take on the city of Chengdu.

“Now that I am back at Hope, my time in China has stuck with me by expanding my international interests here on campus,” says senior Andrew VandeBunte, a business major from Byron Center, Michigan, who enrolled in “China’s Modern Growth.” “In China, we were able to interact with Chinese university students which was a unique way to hear their stories and experiences. This makes me want to build more international relationships on Hope’s campus.”

Senior Clare Da Silva, a biology major from Danville, California, concurs, as she took note of cultural comparatives while on the “China: Land, Wildlife and Culture” May Term. Travel abroad heightens one’s awareness of a home-country’s normative ways of life. Da Silva noted American social conventions in sharp contrast with Chinese ones.

“Since my return to the United States, I have become more aware of cultural norms in American society that emphasize individualism and govern how we interact with one another,” she says. “In China, I maintained a greater respect for the collectivism that has characterized the growth and fellowship between members of society. By comparing and contrasting the two cultures, I have been able to reflect on different ways to combine the visions of each country to become a more informed human being with a deeper sense of responsibility to myself and others.”

Exploring Tangjiahe

Such words of introspection are music to the ears of Hope educators. In hearing them, they know that some of their course goals and objectives have been met, no matter the subject matter. To be able to teach those lessons in China was both a necessity and a privilege.

“China is big enough and important enough that it really can’t be ignored,” explains Dr. Stephen Smith, professor of economics and co-leader of the “China’s Modern Growth.” Smith, who grew up in Hong Kong and specializes in international economic development and growth, adds, “We felt in terms of the international footprint of the Department of Economics and Business, we just had to have something that invited students specifically to think about China.”

At the Kwai Tsing Container Port in Hong Kong

Dr. Tom Bultman, professor of biology and co-leader of “China: Land, Wildlife and Culture,” agrees from both a biological as well as a interdisciplinary standpoint. “China is huge player in the world in all sorts of areas,” he says, “so it’s really important for our students to get some exposure beyond what they read in the newspaper.”

For Dr. Jianhua Li, associate professor of biology and co-leader with Bultman of “China: Land, Wildlife and Culture,” teaching in China was a brief homecoming — just as Hong Kong was for Smith. Li grew up in Henan in central China, and he wished to show Hope students not only his rural homeland but its cultural and urban features too. Biological outings stood side-by-side on the itinerary with trips to The Great Wall, The Forbidden City and the Summer Palace.

The goal was to show as much of a spectrum of Chinese life as possible in a short period of time.

“We wanted (our students) to see China in a kind of totality because in the media we either see Shanghai with its big, modern buildings, or we see very remote or very poor areas. Like in the United States, it’s not just one thing or the other. It’s more like a continuum of different things.”

Taking in the Three Gorges Dam

Under Dr. Li’s tutelage, Da Silva got it, particularly from the biological vantage point. She was struck especially by China’s strong commitment to improve conservation efforts throughout the country, a realization she would have missed if not on Chinese soil. “Ecotourism has become essential to the preservation of scarce resources and has allowed for more opportunities to increase revenue in Chinese societies,” she explains. “Throughout this May Term, I was amazed by the fairly successful implementation of government policy to protect natural environments and the species that inhabit them.”

The experience of studying in China positively changed VandeBunte’s outlook not just on China but on life. Before his May Term, he had never traveled outside of the United States. Now he has an affinity not just for international travel but for the lessons that can come of it.

“I fell in love with the Chinese culture and pace of life during May Term,” VandeBunte says. “And I came home with an interest in learning more about other places of the world. I think this can only help as I grow older by expanding my knowledge and preparing me to interact with multiple cultures.”

Birds Against Glass: An Avian Study

In the fall of 2014, biology Professor Dr. Kathy Winnett-Murray and five former Hope students had the unenviable task of seeking out and documenting bird carcasses found beneath the windows of six campus buildings.

While the quest to find deceased birds may seem morbid to some, the purpose of their investigation was anything but macabre for Winnett-Murray, whose research focuses on the responses of animals — most often birds — to environmental changes brought about by human alteration of habitats.

Winnett-Murray’s research team, which included Michael Barrows ’15, Nicholas Gibson ’17, Emily Kindervater ’15, Courtney Lohman ’16, and Alexandria Vandervest ’15, wanted to learn if certain buildings, and their locations, were more apt to be deadly to birds than others. They hope their study will eventually save birds when combined with the same research methods conducted simultaneously at other colleges. Together with 39 other research teams across North America, the peripheries of 281 various-sized buildings situated in varying urbanized settings were scrutinized using a standardized search protocol.

At Hope, students paired up daily for four weeks to search the perimeters of Durfee Hall, the Schaap Science Center, Bekkering Admissions House, Gilmore Hall, Oggel Cottage, and the Beardslee Library building on the campus of Western Theological Seminary. Each structure was chosen for its size and landscape variety.

The team’s research was published in the fall 2017 journal, Biological Conservation, and is included in the article, A Continent-Wide Analysis of How Urbanization Affects Bird-Window Collision Mortality in North America. The paper, which lists Hope as a study site and Winnett-Murray as co-author, documents bird-window collisions from Whitehorse, Canada, to Mexico City, Mexico — and 22 United States in between.

Each of the study’s participants, including Hope, is a member of the Ecological Research as Education Network (EREN), a collaborative consortium that “addresses questions that need a vast geographic range in order to provide answers that we (Hope) can’t provide on our own very easily,” says Winnett-Murray.

“I got involved with the project out of concern for a lot of ways that people have changed the environment that both benefit wildlife or harm wildlife,” she said. “We don’t really understand the subtleties very well at all.”

Dr. Kathy Winnett-Murray, professor of biology

Not surprisingly, the study confirmed that bigger buildings kill more birds. That’s  the direct effect of larger surface areas. But what surprised the study’s authors was a finding that could have only emerged by comparing multiple sites.

Over the course of their month-long research, the group found just 12 dead birds. That’s good news if you’re a bird, but it was sometimes monotonous for the research team. “We went a lot of days without finding anything so I was a little bit concerned that we weren’t going to be able to provide much information for the study. Turns out some sites found zero bird carcasses,” Winnett-Murray said.

“We were thorough,” Winnett-Murray remembers. “First, Greg Maybury (director of operations at Hope) provided us with each building’s footprint measurement. From there, we had to measure the window surface areas on each of the six buildings. That was a lot of work. You would be very surprised by all of the different window sizes on individual buildings. We photographed each outside building wall, determined how many windows of each size there were, and then we used image analysis on the digital photos to determine how much total glass was on the outside of each building.

“Finally, we walked, really slowly around each building, doubling over each other’s steps, and scoured under ivy, through plantings, in window grates,” she recalls.

The bird crew also worked closely with Hope’s physical plant staff in another way. “We informed their staff about our project to explicitly ask them NOT to remove any bird carcasses from around buildings while our study was in progress.”

Not surprisingly, the study confirmed bigger buildings kill more birds. That’s  the direct effect of larger surface areas. But what surprised the study’s authors was a finding that could have only emerged by comparing multiple sites: Birds were disproportionately dying from window collisions when large buildings were situated in a rural landscape, as opposed to urban ones.

“The buildings with lots of greenspace and landscaping around them, and fewer other buildings around, were absolutely deadly,” Winnett-Murray says.

“We’re inadvertently drawing birds into a dangerous place with a lot of glass that they’re going to smack into and die,” she contends.

One reason for this, she surmises, supports the beacon hypothesis: Birds are attracted to appealing areas where they can find food and rest. And sometimes those areas are right next to buildings’ windows. “We’re inadvertently drawing birds into a dangerous place with a lot of glass that they’re going to smack into and die,” she contends.

The irony is that the more wildlife-friendly the habitat next to a building, the more birds are potentially killed. So what can be changed to prevent this unintended consequence?

Winnett-Murray suggests new construction or renovated building projects can use LEED-certified windows that reflect light to reduce bird-window collisions. Landscape architects can put more distance between landscaping and building windows, and homeowners should not put bird feeders right next to windows.

“I think that most people are aware that once in a while birds smack into glass,” says Winnett-Murray. “But I think people are very unaware how some places are hurting birds more than others. I hope this paper — which has already gotten a lot of traction — helps get the word out to the public so we all can make a difference to help save birds.”

Uncommon Class on Common Grounds

It’s the second-leading commodity traded in the world after oil, with a worldwide consumption of 2.2 billion cups per day. And, the United States is its leading consumer at 400 million cups daily. Yet, few people are aware of the scientific, political, historical and cultural implications swirling inside their cup of morning joe.

This is not the case for Hope students who take Dr. Tom Bultman’s new class, The Science and Culture of Coffee. They are getting a thoroughly flavorful education about everything they ever needed or wanted to know about coffee.

True scientific experiments are conducted using coffee as the vehicle to construct hypotheses, make predictions, collect data and evaluate outcomes.

Angelique Gaddy measures the acidity of coffee using a pH meter.

Offered for the first time this spring, Bultman’s two-credit coffee course is just one of two of its kind taught at colleges and universities in the U.S. as far as he can tell (the other is offered at UC-Davis). While there are dozens of barista schools in the country that teach their students how to roast, grind and brew the perfect cup of coffee, this new class for college credit goes much deeper than that. True scientific experiments are conducted using coffee as the vehicle to construct hypotheses, make predictions, collect data and evaluate outcomes. How do acidity levels change in beans due to varying roasting times? What happens to the mass transfer of water and grounds during the brewing process? What is the anatomy of a coffee cherry fruit and how are beans harvested from within?

There are history lessons, too, about the global trade of the Coffea arabica beans and bush — a plant native to Ethiopia that helped create early agricultural routes throughout the sub-tropical world.  Bultman, a professor of biology, also covers ground on the way coffee affects national economies, personal health and policies on fair trade and human rights. And knowing how much college students love their coffee for its social and caffeinated benefits, Bultman’s course is listed under Hope’s General Education Math and Science offerings which target non-science majors. It’s gives its pupils one truly eye-opening experience.

“This class has definitely increased my appreciation of coffee, especially in the roasting of it,” says sophomore Sarah Kalthoff of Carmel, Indiana. “I see all of the work and love that goes into the process. Coffee really brings people together throughout the world and I now recognized that when I go to a coffee shop here. So many people around the world — farmers, families, fair traders — are affected by the cup of coffee I’m drinking so it’s been great to see how coffee brings cultures together.”

From left to right. Sarah Lundy, Kirsten Kettler, and Savanah Stewart roast green coffee beans using a air popcorn popper, tin can, cooking thermometer, and iPhone timers. Coffee chaff from the roasting surrounds the popper.

Students in the class roast green coffee beans nine times during its half-semester schedule, using makeshift roasters that consist of an air popcorn popper, a tin can, and a small cooking thermometer. As the chaff from the beans pops like confetti from the contraptions’ tops during the roasting process, the lab becomes the best smelling classroom on campus. Students monitor the time, temperature, color and odor of the beans. Then later, they’ll brew and drink their roasted creations, experiencing the process of “cupping” to learn to how to discern and evaluate the taste of flavor notes — chocolate, butterscotch, molasses, raisin, for example — that are subtle but evident in good beans.

Gerrit Immink cools his beans.

As if getting free morning coffee isn’t benefit enough (the course is offered at 9:30 am on Tuesday and Thursdays), Bultman even sets aside a class period for his students to learn how to create their own coffee mug in Hope’s ceramics studio under the guest tutelage of art professor Billy Mayer. Field trips to area businesses that roast and retail are also on the course syllabus.

Not surprisingly, this class on coffee has grown in popularity quickly. It’s been full to the brim each time it’s been offered (twice thus far) and the buzz around campus is that more students are clamoring to get in.

In this class, because all of us drink coffee, the knowledge is applicable to us. And we’re taking a class we’d never expect to take in college. This class to me is the definition of a liberal arts education.”

“It’s been a blast,” say the middle-aged Bultman who took up drinking coffee just three years ago and now admits to being a coffee geek. “Everyone who enrolls drinks coffee so it means something to them. And so many students don’t think about where coffee comes from or how it’s grown or brewed, it’s just one of those things we easily take for granted. Now they are more appreciative of all the work that goes into coffee before they sit down and drink a cup.”

“I technically didn’t have to take this class because all of my science requirements were done but when I saw the poster about it, I knew I had to take it,” comments junior communication major Sarah Gallagher of Chicago, Illinois. “A lot of college students who are not science majors say science and math classes are impractical to their lives but in this class, because all of us drink coffee, the knowledge is applicable to us. And we’re taking a class we’d never expect to take in college. This class to me is the definition of a liberal arts education.”

The First Great Inoculation Debate

A heated debate rooted in a distrust of science about the safety and effects of childhood vaccinations has, in recent years, been under a microscope in this country. But another inoculation debate raged in the U.S. almost 300 years ago, and it was this tense, centuries-old discourse, rooted this time in both scientific and religious misgivings, that became junior Elizabeth Ensink’s research focus during the summer of 2015. Her original work on the topic earned her a prestigious place at last week’s 20th annual national Posters on the Hill event in Washington, DC, a selective poster session sponsored by the Council on Undergraduate Research (CUR).

Ensink.DC

One of only 60 projects selected for this year’s showcase from among several hundred highly competitive applications nationwide, “The First Inoculation Debate: A Quantitative Text Analysis of the Boston Smallpox Epidemic of 1721” by Ensink, looks at communication practices between doctors and religious leaders when a smallpox epidemic broke out in Boston. Puritan ministers saw inoculation as distrust in and interference with God’s will; doctors fumed at the meddling of ministers and “unlearned men” in scientific affairs; and all the while colonists, fearing for their lives, just wanted people in positions of authority to give them clear words of encouragement and actions of help.

It all sounds so familiar even today. History tends to eerily, annoyingly repeat itself.

Ensink, who is from Hudsonville, MI, became interested in the inoculation topic when looking through the digital Contagion Collection – historical documents about various epidemics and diseases – from Harvard. As a Mellon Scholar, she was set to conduct summer research after her sophomore year, and as a biology and creative writing double major, Ensink felt she found the right subject for her interdisciplinary interests.

So, using digitized documents and an online text analysis tool called Voyant, Ensink analyzed words that pro- and anti-inoculators would frequently used in their letters and other documents – words such as God, belief, providence, and symptoms, infection and incision. Not surprisingly, she found that doctors used mostly secular language and ministers spoke more in religious terms.  All except for Cotton Mather.

“This subject showed me how important it is to have people know how to communicate science to the general public. One of the most important parts of my research was questioning how we get meaning from words that are being used to convey vital messages.”

Mather, the fiery Puritan minister best known for his involvement in the Salem witch trials, was supportive of inoculation when he learned of it from his African slave and a report from the Royal Society of London, Ensink learned. Mather then encouraged Dr. Zabdiel Boylston to start inoculations. Though the practice was successful – 6,000 infected, 844 deaths overall, 280 saved due to inoculation –Mather and Boylston came under attack for the practice. And often it was because of the words they did or did not use.

“This subject showed me how important it is to have people know how to communicate science to the general public,” says Ensink. “One of the most important parts of my research was questioning how we get meaning from words that are being used to convey vital messages. In this case, religious and secular language was often blurred.”

Ensink presented those findings with her poster for two hours in the Rayburn Building on Capitol Hill, where she also had the opportunity to engage with other students from Georgia to Utah, about biochemistry and anthropology and other various subjects. “This event exposed me to diverse projects and people from diverse institutions. It was an honor.”

After the prevention of her poster on the Hill, Ensink and Dr. Karen Nordell Pearson, associate dean for research and scholarship, had the opportunity to meet with Congressman Bill Huizenga at his office in the  Capitol. “It’s really cool that in America we can go and talk to our representatives in government about what we think is important. “

And what did they talk about?

“I told him that undergraduate research should continue to receive federal funding. Events like Posters on the Hill show what students can do when funds are available.

“I also let him know how important programs like Mellon Scholars are to undergraduates. Being in Mellon allowed me to develop my own project, gave me greater critical thinking skills and a great mentor who I met with twice a week.” Ensink’s mentor, Dr. Jonathan Hagood, is an associate professor of history at Hope College. “I learned self-motivation and the ability to overcome obstacles. This work stretched me and confirmed that in the future I want to focus on science and writing.”

In every way, Ensink’s research, and her experiences because of it, have given a potent shot to her strong academic arm. “I’m so thankful for the Mellon Scholars Program for all of this,” she concludes.

Breaks Away: Tom Bultman

sabbatical (n): a break from customary work to acquire new skills or knowledge, traditionally occurring every seventh year

Breaks Away: Sabbatical Stories of Hope
Each academic year, a number of Hope faculty take sabbatical leaves away from the college, submersing themselves for extended periods of time into their favored fields of inquiry. If viewed from above and all together, those fields would look like a calico landscape, so varied and colorful is the topography of their collective research, writing, and creative pursuits. Offering restoration and adventure both, sabbaticals are a bit like information and imagination transfusions. These breaks away from normal classroom and committee work give Hope academicians a boost to reinforce and revitalize their teaching and scholarship.

Sheep in New Zealand have a friend in Dr. Tom Bultman. And Dr. Bultman, professor of biology, was happy to oblige the massive, wooly industry that is valuable in a country where sheep outnumber humans by about 10-to-1.

Funded by a National Science Foundation grant and headquartered at AgResearch just outside of Christchurch, Dr. Bultman spent three months in the spring of 2015 investigating the growth and effects of endophytic fungus inside perennial ryegrass, the mainly foraged food source found in New Zealand paddocks. His research findings may eventually ensure that New Zealand’s ovine population (and America’s too) can eat their meals toxin-free.

“Endophytic fungus can produce chemicals in the grasses that can be toxic,” explains Dr. Bultman, who collaborated with six other New Zealand scientists, as well as Hope graduate Kelly Krueger ’14, on the project. “So it makes sense that ridding the grasses of those fungi and possible toxins is important to farmers in New Zealand and the U.S. because the effects of the fungi are pronounced in these two part of the world.”

Dr. Bultman and associates also looked at the alkaloid levels — the presences of nitrogenous compounds — in damaged grass and the insect impact on that grass as well. In other words, when ryegrass is walked on by sheep hooves or torn by the sheep’s teeth, what alkaloid, if any, would be produced and how would insects respond to it?

“We found that one variety of fungus actually produced reduced alkaloids in damaged grass, probably due to the sheep’s saliva,” Dr. Bultman says.

So in layman’s terms, sheep spit is actually a good thing.

“I’m a pretty simple guy, I admit,” he replies when asked what he appreciated most about his break away, “so sabbaticals are the chance to simplify, to focus on one thing for a big block of time. This research is new and novel, and I can’t wait to write it up.”

With most of his findings in hand, Dr. Bultman will now begin to author his work for publication in scholarly journals such as PLOS Biology. In fact, he’s anxious to do so.

“I’m a pretty simple guy, I admit,” he replies when asked what he appreciated most about his break away, “so sabbaticals are the chance to simplify, to focus on one thing for a big block of time. This research is new and novel, and I can’t wait to write it up.”

Dr. Tom Bultman is a professor in the Biology Department at Hope College.
