Eight presentations were made by 14 biology, , and students that showcased the breadth and depth of research opportunities available at EMU.

The symposium provided an opportunity for students to share their research with an audience of general science majors, said department chair and professor of chemistry . One of the skills of a scientist, she says, is 鈥渢o be able to present technical terminology and processes in accessible language. It鈥檚 great if a scientist can study climate change, for example, but if we can鈥檛 explain the results of a climate change study to someone who doesn鈥檛 have the background, that doesn鈥檛 help us share and discuss our findings.”

The evaluation 鈥� led by , professor of chemistry at James Madison University 鈥� included three criteria: collection of data, thoroughness of research design and analysis, and clarity and accessibility of the oral presentation.

Second place was awarded to junior Hannah Daley for her presentation about her National Science Foundation-sponsored research, in partnership with two professors at James Madison University, on the effects of caffeine on athletes.

Sophomore Kat Lehman and junior Diego Barahona were awarded third place for their research on utilizing radio-tracking to locate coconut rhinoceros beetles鈥� breeding sites, which was conducted under the direction of chemistry professor in Guam. Siderhurst has worked for several years on research projects involving the development of attractants for invasive and agriculturally important pests.

Students find their niche in grant-funded studies

Research projects often pair students with professors engaged in long-term studies. The competition winners, Ferguson and Fernandez, were research assistants to Professor , who earned a $100,000 Jeffress Trust grant to study a multi-year investigation into the causes of hypertension. In Ferguson and Fernandez鈥檚 project, rats were fed a high fructose, high salt, low salt, and no salt diet and measured the activation of genes involved in disease.

The STEM symposium is also offers students like Hannah Daley and Janaya Sachs, who both earned grants to engage research opportunities off campus, to share what they鈥檝e learned. Sachs explored a new ligand for synthesizing copper, a summer project she engaged in through the National Science Foundation Research Experience for Undergraduates. She worked at .

The bioorganic copper project is just one of several research opportunities she鈥檚 been involved in. Her freshman year, she joined , led by , director of the MA in biomedicine program, and supported by a grant from the U.S. Department of Agriculture. She and Hannah Daley are both currently involved in evaluating the effects of hydrofracking on stream and well water, a project under the direction of and Kishbaugh.

Among the research shared, a unique transdisciplinary project was conducted by biology major Samuel Miller and computer science major Alex Bender, advised by Siderhurst and computer science professor . Miller conducted a chemistry project that involved identification and quantification of volatiles released by the noni fruit during ripening that provided a complex data set that was difficult to analyze. Bender and Miller have both used a mathematical technique called Principal Component Analysis to analyze the results in a simpler manner.聽 Bender is documenting their methodology for PCA usage, simultaneously evaluating software programs Cluster 3.0 and SPSS for their ability to simplify the data set.

Flavenoids, genetics, mold…

Professor , who teaches courses in genetics, cell biology, microbiology and immunology, advised several research projects. Biology major Chris Miller researched the effect of anthocyanins, richly concentrated plant colorants that may have protective effects, on mouse fetal development when the mice are exposed to a significant amount of alcohol.

Derek Harnish and Eli Wenger presented their research on the neuronal basis of aging in flies. Harnish, a biology major, and Wenger, a biology and biochemistry double major, worked with Copeland on his ongoing project to identify specific types of that have the potential to extend lifespan in flies when the mitochrondrial electron transport chain is disrupted.

Biology majors Viktor Kaltenstein and Seth Suttles teamed up to study mold growth in a vacated section of the Suter Science Center campus using the Environmental Relative Moldiness Index (ERMI).

Daley, who is planning a career in environmental chemistry, is a junior double major in and at 草莓社区 (EMU). She participated in a 10-week internship through the (REU) program that placed her with professors at nearby James Madison University (JMU).

And while she hasn鈥檛 quite yet fully answered the question, Daley says her experience in a large lab setting gave her valuable confirmation of her present and future choices: EMU, she says, is the right place for her, providing strong skills-oriented training and confidence so that in a few years, she鈥檒l be ready for a more competitive lab environment.

Two from EMU participate

REU is 鈥渁 widely recognized research program that provides undergraduates with the chance to work in a larger university lab setting,鈥� says Daley.

Chemistry professor, Daley鈥檚 academic advisor, recommended the program. 鈥淥ften as many as 200 applicants are competing for about 10 spots,鈥� Kishbaugh says. 鈥淭he program is designed to help students at primarily undergraduate institutions have a research experience similar to that they would have in graduate school. And it can help students discern if graduate school is something they would enjoy as well as what sub-disciplines might interest them.鈥�

Kishbaugh says an average of two EMU students earn an REU each year. Junior Janaya Sachs, also a chemistry major, was involved last summer with research at the University of Minnesota.

Cyclists and caffeine

Daley worked in the labs of James Madison University (JMU) professors Christine A. Hughey and Christopher Womack. Hughey is an analytical chemist who worked directly with Daley while Womack is the kinesiology department head who oversaw the entire experiment.

Analytical chemistry, as defined by the American Chemistry Society, is 鈥渢he science of obtaining, processing, and communicating information about the composition and structure of matter 鈥� the art and science of determining what matter is and how much of it exists.鈥�

Daley was quantifying how caffeine was metabolized in human serum.

In the experiment, participants ingested either caffeine or a placebo and participated in a cycling workout. Following the workout, a blood sample was taken.

鈥淭he blood would be purified into human serum,鈥� Daley says. 鈥淚 would get the serum and I would extract and quantify the amount of caffeine and its three primary metabolites present in the serum.鈥�

Daley explains that the body breaks down what it ingests 鈥� caffeine in the case of her experiment 鈥� into metabolites that can be used by the body. 鈥淭he overall goal of the research was to determine if individuals of different phenotypes metabolize caffeine at different rates when exercising and if that rate is correlated with an ergogenic benefit.”

Daley鈥檚 role in the research process was to develop a method to quantify the ratio of caffeine and its metabolites using an instrument called the 鈥淯HPLC鈥� to measure exactly how caffeine metabolization varied between athletes and was affected by exercise.

UHPLC is an acronym for ultra high performance liquid chromatography, which was coupled with UV detection and positive electro-spray oonization and mass spectrometry.

Though Daley鈥檚 summer internship is complete, the experiment is still ongoing. Daley will be on call this fall, assisting in the lab when needed. If the findings are published, she will gain valuable academic credentials to match her experience in the lab.

First-generation student-athlete at home at EMU

Daley enjoyed working in the lab at JMU, and fed off the competitive energy from those around her, which made it easier to be excited about her work. The topic also interested her; she鈥檚 a goalkeeper on the and athletics are an important part of her life.

Her REU research experience this summer, Daley says, was invaluable. She鈥檚 now worked with similar instruments and techniques that she鈥檒l use in environmental chemistry, and 鈥済ained a lot of skills that will help me in my career path.鈥�

Daley says EMU prepared her well for the competitive and fast-paced research environment and she鈥檚 now a more confident scientist and student.

鈥淚 look forward to going to a larger school for my graduate education, but I like that I am going to a smaller school as an undergraduate. I have good professors here and good friends in the program who provide support,鈥� says Daley, a first-generation college student who came to EMU because of its commitment to sustainability and its strong academic program in that field.
