Research Highlight: Ryan Denholm

I had the opportunity to speak with Ryan Denholm concerning his experience participating in an independent study with Dr. Bañuelos Montes which focused on actions committed by the Guatemalan military during the Cold War.

Can you describe what your research project is about?

My research project is about atrocities committed by the Guatemalan military during the latter part of the Cold War. I set out to use testimonial literature (that told through the eyes of individual witnesses) in order to document and analyze the nature of the human rights abuses committed. Additionally, I analyzed the relation of these crimes to the broader geopolitical landscape at the time, which is why I entitled my research “El costo humano de geopolítica” (the human cost of geopolitics). Grave human rights abuses were committed with assistance from U.S. tax dollars, under the pretext of “fighting communism.” 

I read and wrote about two works of testimonial literature: “Death of a Guatemalan Village” by Victor Montejo and “After the Bombs” by Arturo Arias. The former is a work of nonfiction written by a schoolteacher in the indigenous village of Tzalalá who witnessed the military execute civilians. The latter is fiction written through the eyes of an imagined boy, named Máximo, describing the Guatemala that he would have grown up in, marred by violence and destruction. Especially damning is the way that Arias follows Máximo’s growth and development; whereas in the United States many of us take for granted life milestones like falling in love for the first time, in Máximo’s case his first date is interrupted by military men violating his girlfriend. While again, this is a work of fiction, many of these types of crimes (and much worse) occurred within the context of Cold War geopolitics. My completed research becomes, in essence, a rebuke of U.S. Cold War foreign policy in Guatemala for the way in which it aided and abetted some of the 20th century’s most horrific atrocities.

What made you decide to pursue your topic?

My freshman year at Roanoke, I took a Latin American history course taught by Dr. Wallace Fuentes. In that class, for the first time, I began to gain a more clear picture of the region’s history and its relation to broader geopolitical discussions. Prior to college, as a middle and high school student in public Virginia schools, I was  often taught broad oversimplifications about the Cold War, like that the United States won without anyone dying. Dr. Wallace Fuentes’ course sparked in me a desire to more fully understand the politics of the region and the way that Washington’s power has shaped its development. 

As a Spanish minor, my discussions with Dr. Bañuelos Montes often involved the politics and history of Latin America, as well. Him and I both share an interest to academically explore human rights abuses that were committed in Latin America during the Cold War. Guatemala is the perfect case study of this. 

Why did you decide to do research?

I decided to do research in order to pursue a topic of academic interest more fully, and to work one on one with a faculty member. This independent study with Dr. Bañuelos was a great opportunity to do that. 

How has your experience with your research advisor been?

It has been a pleasure to work with a research advisor as engaged and as knowledgeable in his field as Dr. Bañuelos. He provided me with academic guidance that was invaluable to the completion of my research. I learned a lot from him and the readings that he provided me with.

What has been your favorite or most interesting of your research project so far?

The most intriguing part of my research has been what I have learned about U.S. Cold War policy in Guatemala. As an American who wants his country to pursue good in the world and uplift those in other countries, learning about the atrocities committed in Guatemala with U.S. financial and logistical support is disheartening, to say the least. It has been sobering to learn that while our presidents are happy to pay lip service to ideals of democracy and human rights, when it comes to tangible policy, too often these principles have been ignored. 

For example, in my research I learned that President Reagan, despite having clear evidence of the genocide and atrocities being committed by the Guatemalan military against indigenous people, praised dictator Efraín Ríos Montt as a man of great personal integrity and provided him with military equipment. As an American, this research leaves me with a bitter taste in my mouth and a renewed desire to work towards building a country that actually practices what it preaches, politically.

What would you say to current and incoming students interested in doing research? 

Just do it! I would encourage any students interested in doing research to talk to a professor who is knowledgeable in a subject that they are interested in. By working one on one with a faculty member, I was able to pursue a subject of interest at a deeper level than can otherwise be attained.

Research Highlight: Lauren Powell

I had the opportunity to speak with Lauren Powell concerning her experience presenting research she conducted with Dr. Bucholz at the Society for Personality and Social Psychology’s Annual Convention in New Orleans. 

Can you describe what your research project is about?

The most recent research Dr. Buchholz and I have conducted was a study about the empathic differences between conservatives and liberals. Right now, we are looking at the use of fear appeals in politics, and may focus it on the use of fear appeals within the Trump Administration. 

What made you decide to pursue your topic?

I’ve always thought political psychology was interesting – it’s fascinating to me how two people can have totally different opinions on one single topic, such as gun control or who is deserving of the presidency. Dr. Buchholz is interested in empathy, so for our last project we just merged our two interests together and came up with our topic. For the study we are planning on doing this year, we wanted to continue with the political psychology route and apply it more specifically to today’s political climate. Fear appeals are really interesting because if they are used strategically, it makes persuasion really easy especially in politics. 

Talk about how different it is doing research during these times?

Doing research is definitely a little different, but for my psychology lab at least it isn’t too bad. The only real difference I have seen so far is that Dr. Buchholz and I are meeting via Zoom rather than in person, but we are still doing the same things that we would be if we were in person. Luckily for psychology, or at least my lab in particular, a lot of the research is conducted via surveys that are online anyways, so everything being virtual doesn’t really impact us. It’s just as easy to get in contact with Dr. Buchholz or Dr. Lassiter through email, which is nice. Having technology is definitely helpful! 

Talk about being a Research Fellow?

Applying to become a research fellow was hands down the most useful, productive, and important thing that I did at Roanoke. I remember before I started college, my brother told me that it was important to try and get involved in research especially as a psychology major with plans for graduate school. The Research Fellows program is awesome! You not only get the experience that is absolutely crucial for pursuing a masters degree or Ph.D. early, but you also get course credit and you get paid. Having the extra GPA boost each semester from the course credit I receive in return for doing research is always nice – I know that I work hard in our lab and it’s nice that my hard work and dedication to the research reflects on my institutional GPA. It’s also nice getting paid to do something I love to do!

 

Research Highlight: Amber Gregory

I had the opportunity to talk to recent RC grad Amber Gregory about her research experience. She presented her research at the Southeast Decision Science Institute earlier this year (February 2020).

We researched how Instagram affects one’s personal wellness, that being, anxiety, depression, tendency of eating disorders, and self-confidence. The members of our group picked this topic as Instagram is one of the fastest growing forms of social media, and we felt that it had negative effects. The conference itself was a great experience. It was nice to see what other people had to present, and we learned a lot. We presented in front of a small group, which was really nice because we felt comfortable when presenting. I think our topic was interesting to others because it’s very relevant and Instagram is so widely used. I think it’s good that people are made aware of the negative effects. 

Research Highlight: Jamie Obremski

I had the opportunity to talk to recent RC grad Jamie Obremski about her research experience. She had the opportunity to present her research at the Southeast Decision Science Institute (February 2020).

Why did you decide to do research?

I am a part of the Honors Program here at RC and this research is a part of my Distinction Project.

Can you describe what your research project is about?

My research project is on the topic of financial literacy in college students.  I worked on measuring the financial literacy, or lack thereof, of Roanoke College students and determining ways to lessen this gap.

What made you decide to pursue your topic?

One of the biggest gaps experienced by college students is financial knowledge and responsibility. Students are beginning to take more control over their personal finances at this age and lack the skill and knowledge to make responsible financial decisions. Therefore, I wanted to see if there was any way to help resolve this issue since it is such an important life skill.

Talk about the conference experience?

Attending this conference was a positive experience for me. I was exposed to a lot of different levels of research, some from college students like me and some from experienced professionals.  I enjoyed being able to learn about different projects being done and also hear some feedback about my own project from outsiders.

Why would someone be interested in presenting your findings at a conference?

Financial literacy is a topic that everyone needs to have familiarity in. As students grow older and have to face the “real” world, it is becoming apparent that the education system is not doing well at preparing students for this responsibility. Making this more well-known will hopefully bring attention to this issue and help find a way to resolve it.

Research Highlight: Savannah Faith Clark & Christian Sanchez

Savannah Faith Clark and Christian Sanchez are current juniors at Roanoke College. They had the opportunity to present their research at the Virginia Academy of Science Undergrad Meeting. I asked them questions to get an insight of their experience presenting and what conducting research at Roanoke College is like.


Can you describe what your research project is about?

The purpose of this study is to examine strength, muscle power, and range of motion in the affected arm (arm where breast cancer was present) compared to the unaffected arm in breast cancer survivors. Since breast cancer treatment results in impaired upper body function, more research is needed to examine the extent of losses in the affected arm compared to the unaffected arm. In addition, we plan to examine individual arm strength, muscle power, and range of motion in the upper body of breast cancer survivors compared to women who have not had breast cancer.

What made you decide to pursue your topic?

This project is an extension of research that our adviser, Dr. Ashley Artese, has previously done where she found that body fat and bone mineral density were lower in the affected arm compared to the unaffected arm of breast cancer survivors. Therefore, we are interested in how these body composition and bone deficits can impact strength, muscle power, and range of motion.

Talk about the conference experience?

After submitting a research proposal to the Virginia Academy of Science in October, we presented our proposal at a poster session at the Virginia Academy of Science Fall Undergraduate Research Meeting. The competition consisted of 40 undergraduate posters from other colleges in Virginia. Each poster was presented to three judges who evaluated the written proposal and our oral presentation. We were the top nine posters that were awarded a $750.00 research grant. We will present the results of this project at the Annual Spring Meeting.

Why would someone be interested in presenting your findings at a conference?

Findings from this study will provide a better understanding of long-term side effects of treatment on strength, muscle power, and range of motion in affected and unaffected arms in breast cancer survivors and how those outcomes compare to women who have not had cancer. Results may impact how healthcare providers use exercise as an additive during and after treatment to prevent potential losses in functional outcomes in the upper body.

Research Highlight: Stephanie Zemba

I had the opportunity to talk to Stephanie Zemba a current junior at RC. Not only did she have the opportunity to conduct research in the summer, but she also presented her research at MARCUS (Mid-Atlantic Regional Conference of Undergraduate Scholarship). I asked Stephanie a few questions to get her insight about what her experience was like.

Can you describe what your research project is about?     

I am doing a research project with Dr. Mehrotra that examines whether and how social isolation is experienced by older immigrants living in Southwest Virginia, an area with few large ethnic communities. In addition to exploring the factors that contribute to isolation and loneliness among this group, I was also interested in how they reduced loneliness. I conducted over 40 semi-structured interviews with immigrant elders this summer and fall. For MARCUS, I presented on the three primary ways that older immigrants described reducing their loneliness—maintaining strong family and friend relationships, becoming involved in a religious community, and continuing to practice their culture (cultural continuity).

What made you decide to pursue your topic?       

The topic of immigration was brought up in my Global Perspectives on Family class (SOCI-329) and I was interested in learning more about it. My grandfather was an immigrant from Germany, which also contributed to my interest in immigration. In addition, I came across a news article about the growing problem of loneliness among older adults. I was talking about my ideas for potential research topics with Dr. Mehrotra and when I mentioned both these interests, she said, why not look at both? One of the first articles I found presented a seeming contradiction—late-life immigrants who came to join family members still experienced loneliness despite being embedded in a strong family network. Moreover, since so few researchers have actually focused on isolation among foreign-born elders, it was a promising area. Once I looked into it more, I was hooked!

Talk about the conference experience?      

 I think presenting at MARCUS was a great experience. I wouldn’t describe myself as much of a public speaker, so the idea of signing up to do a 12-minute presentation seemed really daunting at first. However, everyone I talked to said it would be a good way to become more comfortable with speaking in front of people, especially considering that I want to present at a regional sociology conference in April. I also plan to earn a PhD and become a sociology professor, so public speaking is definitely a key skill to build. Before the conference, Dr. Mehrotra and I met every 2 or 3 weeks so that I could become more comfortable with public speaking and get feedback about how to improve. Despite all this preparation, I was still nervous on the day of the actual presentation, but it went very well and I received a lot of interesting questions from the audience.

Why would someone be interested in presenting your findings at a conference?      

Presenting at an smaller undergraduate conference like MARCUS is a great way to “get your feet wet” and practice for larger national or regional conferences. It’s also a good strategy for getting feedback on your work and exploring new directions for research, as audience questions can make you think about your findings in another way.

Research Highlight: Dr. Sarisky, Caroline Hunter, Nicholas Plymale, & Kevin Smee

Some of our fellow RC Maroons were recently published in The PLOS Journal. Dr. Sarisky and 3 recent RC graduates, Caroline Hunter, Nicholas Plymale, and Kevin Smee published their paper “Experimental characterization of two archaea inosine 5′-monophosphate cyclohydrolases”. RC Research had the opportunity to hear from Dr. Sarisky and Caroline Hunter about this accomplishment and their research.

I’m an enzymologist, which means I study enzymes.  With the explosion in the number of sequenced genomes, we have a tremendous amount of genome-level data, but far less experimental characterization.  So we have literally millions upon millions of apparent genes, whose enzymes have been labeled by a computer (sometimes vaguely) about what they might do, but very few have been actually characterized at the protein level. In this paper, my students and I looked at a couple of enzymes called “inosine 5′-monophosphate cyclohydrolases” from two species of archaea.  These enzymes had never been characterized before, and their gene assignments were based on pretty distant relationships.  These enzymes are interesting because they close up the second ring needed to make purines (those are the As and Gs of DNA), and because they’re from organisms that live at very high temperatures.  One of the two enzymes ended up being most active at 80 degrees C (which was as high as we could measure).  That was pretty interesting, since lots of proteins are unfolded (and non functional) at that temperature. 

—Dr. Sarisky

I thoroughly enjoyed my time at Roanoke College, from the fantastic classes, to professors, to the extra-curricular activities; however, none of these were comparable to my research experience in Dr. Sarisky’s lab. From the first day I stepped into her lab to do my summer research project, I fell in love with research and my life wasn’t the same. I planned on going to medical school after graduation, but after doing research, trying to answer a question no one has before, I realized that this was my passion. Not only was our research project “Experimental characterization of two archaeal inosine 5′-monophosphate cyclohydrolases” fascinating to me, but it also gave me invaluable cognitive and laboratory skills that set me apart from other applicants when applying to graduate school as well as provided me with a strong foundation for my own PhD research project at Marshall University School of Medicine. I am forever grateful for the experience I had at RC, especially doing research with Dr. Sarisky, and am thrilled that our research was published for others to see. For the students who aren’t sure if they want to do research, my advice is try it, you never know how it will turn out.

Research Highlight: Dr. Johann, Casey Cooper, Matt Bryant, & Naomi Hogan

Some of our fellow RC Maroons were recently published in The Protein Journal. Dr. Johann and 3 students, Casey Cooper (Wojtera while at RC), Matt Bryant, and Naomi Hogan, published their paper “Investigations of Amino Acids in the 5-Formyltetrahydrofolate Binding Site of 5,10-Methenyltetrahydrofolate Synthetase from Mycoplasma pneumonia”. RC Research had the opportunity to hear from Dr. Johann and Naomi Hogan about this accomplishment and their research.

Enzymes are biological catalysts; they speed up chemical reactions.  Our work focused on structure/function relationships in 5,10-methenyltetrahydrofolate synthetase (MTHFS).  This enzyme is important in that it converts a storage form of tetrahydrofolate into a useful form.  Tetrahydrofolates are typically made in the human body starting with the vitamin folic acid.  In some cancer treatments, this process is blocked to semi-selectively kill cancer cells.  Normal cells are then rescued using the storage form of folate that the enzyme MTHFS helps change into a useful form.

Enzymes are made up of smaller units called amino acids.  We removed specific amino acids in the enzyme MTHFS and replaced them with other amino acids.  We then studied if the enzyme worked as well as it does with the natural amino acid.  This helped us to determine the role that those amino acids play in the function of the enzyme. 

—Dr. Johann, Chemistry

“Doing research over the summer gave me the opportunity to see more realistically how a lab functions.  It gave me the chance to determine whether research is the right choice for me when pursuing a career. There is a lot more effort that goes into the process than publications show, as well as a lot of failures before a success. Being published is a very marketable achievement. It will help me secure a career with an employer that values research and all of the trial-and-error that goes into it. I greatly appreciate Dr. Johann giving me this golden opportunity to enhance my future career.”

Research Highlight: Erin McDonnell

Recent graduate Erin McDonnell had the opportunity to present at SDB conference with Dr. Lassiter. I had the opportunity to interview her and get her take on her conference experience.

Can you describe what your research project is about?

At its core, my research project centered around ideas of Behavioral Neuroscience and Toxicology. My experiment looked at the development of zebrafish embryos while being exposed to a chemical compound called Tributlytin (TBT).  I measured brain areas of certain regions and the length of the notochord through phase contrast microscopy. Once the brain had been imaged, I let them develop further in the chemical environment to the age where they could swim and tested for a specific behavioral response. The response that I measured was how long the embryos swam around after being startled.  This was done in order to establish a link between the chemical’s effects on the body as well as later developed behavioral patterns that may be extrapolated to humans. 
We found that TBT does have an impact on how the brain and notochord develop as well as how larvae interact with their environment. Specifically, my research showed that exposure to this chemical, even at 0.1 nM, decreased the size of the forebrain, increased the length of the notochord and increased the amount of time the larvae stayed in a startled state. Other behavioral abnormalities were also found that offers many doors in future directions for expanding the project.

What made you decide to pursue your topic?

         Ultimately, I wanted to work on a project that truly integrated both Psychology and Biology to greater explore the neurological, and I have always had a fascination with the “black box” of Psychology, the concept that the mind can only be explored in matters of influencing input and describing the output. This concept of what is going in affects what is there and changes something that is expressed was an attainable premise to build upon, and is the idea that the project centers on. Marrying that idea to another of my major interests of not knowing how certain drugs and chemicals work within living systems is how I decided to pursue the full topic of the project. 

Talk about the conference experience.

The conference that I went to was the Society for Developmental Biology’s 78thannual meeting. The conference spanned a variety of developmental biology topics such as Evolutionary Biology, Epigenetics, modeling human pathologies, Regeneration and Organogenesis, and new live imaging techniques. My research was accepted for presentation during a poster session that had other neurodevelopment and related projects from all over the nation as well as a few from visiting countries. This was my first conference ever, and at first it was a tad overwhelming. Once I got into the rhythm of the conference, however, everything was incredible.  I learned so much about things I had never even thought about before, all while having a great time interacting with new people and getting to see a different side of my professor. Going to a conference is yet another way to experience a field of study in a more hands on way. I got to hear from top minds in the field and people on more my level of study about the research they have done, where the field is going, and also just simply what excites them about science. It was a whirlwind experience that I think everyone that can, should have. It is also one that, no matter who you are, will gain something from it.  

Why would someone be interested in your findings at a conference?

Personally, I wanted to present my findings at a conference in order to get the experience of presenting as well as network with people I would likely never have the opportunity to meet outside of that conference. It is one thing to present to a room of peers, or even colleagues, but presenting in a space filled with strangers of who most have advanced degrees and want to speak with you about your work is another. It is one that is exhilarating, at times nerve wracking, but in its entirety unique.
While I am a bit biased, my findings alone were intriguing due to the unexplored nature of the chemical I chose and what I ended up finding. I wanted to get the chance to tell other people about what I had done and found.  I was looking at zebrafish and how they reacted in ways that I thought might be seen affecting humans. So not only are there developmental and purely biological implications, but one might be interested in presenting my research at a conference that focuses on health, environmental risk factors for disease or human ecological impacts.  I would love to have someone take a look at the work that I have done and expand on it. My project was meant as a stepping stone that I hope a student will take up in the future.

Summer Scholar Research Highlights

Stephanie Zemba ’21

Major: Sociology

Title:Social Isolation Among Aging Immigrants

Abstract: Health consequences of social isolation are well-documented. Older immigrants are particularly vulnerable to social isolation due to the stresses associated with aging in a foreign country. The projected increase in foreign-born elders makes social isolation an important phenomenon to study. The proposed research will employ semi-structured interviews to explore whether and how social isolation is experienced by immigrant elders in the Roanoke Valley. Investigating social isolation among immigrant elders who live in an area where their ethnic group is underrepresented will provide a greater understanding of the challenges these elders face and potentially help local organizations address their needs.

Something about the scholar: Stephanie is a junior at Roanoke College, majoring in sociology. She was born and raised in Greensburg, Pennsylvania. Through the Research Fellows program and an independent study course, Steph is involved with two ongoing research projects in the Sociology department on interfaith dating and nondrinking students. She is a member of the French and Culture Shock clubs on campus, and her hobbies include creative writing, reading, and painting. Her friends like to joke that if you can’t find Steph in the library, you’ll find her attending office hours. Steph’s future plans include attending graduate school, earning a PhD in sociology, and becoming a college professor.


Nathaniel Willis ’20

Major: History, Political Science

Title: Religion and Politics in the Middle East: A Comparative Study of Christian Communities in Egypt, Lebanon, and Israel

Abstract: The relationship between religion and state is an important component of the political dynamic of the countries of the Middle East and North Africa, and while Islam is the predominate religion in these areas, Christian Minorities play a notable role in the region. These communities include the Coptic Christians of Egypt, Maronite Christians of Lebanon, and the numerous Christian churches in Israel and Palestine. This study is a comparative analysis of how each community directly and indirectly participates in the political and civil service apparatuses of their respective countries.

Something about the scholar: Nathaniel is a senior from Bedford, Virginia and is a History and Political Science double major. His primary interest of study is the intersection of religion with the fields of politics and history, which is an interest likely influenced by his parents, one of whom is a professor of religious studies at Lynchburg College and the other an ordained Presbyterian minister. Nathaniel is involved in Roanoke College athletics, having participated for 3 seasons of Cross Country and 2 seasons of Track and Field. Nathaniel has spent his past three years at Roanoke working as a student assistant (churl) for the History Department, as well as spending a semester in Washington, D.C. working as an intern for the U.S. Department of State.
