The H-SC Biology Class of 2015 has been especially productive when it comes to original research. Below are a list of the topics covered by this class in their Departmental Honors and Senior Fellowship projects that gives a flavor for the wide array of research opportunities for present and future students in the Biology Department.
“Effects of herbicides and ranavirus, an emerging infectious disease, on juvenile Red-Eared Slider turtles (Trachemys scripta elegans)”–Davis Carter ’15
“Analysis of substrates on growth performance of Centaurea stoebe ssp. micranthos (Asteraceae) using field and lab studies”–Erik Kellogg ’15
“Greenhouse and Field Studies of the Invasive Aster Centaurea stoebe (Asteraceae) and a Native Competitor Lespedeza capitata (Fabaceae)”–Sean Kellogg ’15
“RNAi analysis of Lag-1 Isoform D in Caenorhabditis elegans, a homolog of Suppressor of Hairless (Su(H))”–Daniel Osarfo-Akoto ’15
“Genetic Engineering of the Murine Melanoma D5.1G4 to Express a Model Antigen for Evaluation of Anti-tumor CD8+ T Cell Responses”–Stephen Woodall ’15
“Synthesis and Application of Small Cationic Peptides as Potential Antibiotics”–Jay Brandt ’15 and Christopher Ferrante ’15 (in cojunction with the Department of Chemistry)
“The Generation of Trichromatic Vision via Adeno-Associated Virus (AAV) Vector Expressing Red-Shifted Channelrhodopsin (ReaChR)”–Aaron Gilani ’15 (in conjunction with the Department of Psychology)
“Evolution of the Eye and its Extreme Capabilities”–Jeffrey Gray ’15 (in conjunction with the Department of Physics and Astronomy)
Each spring, the College of William and Mary invites Virginia participants in the Howard Hughes Medical Institute Science Education Alliance-Phage Hunters Advancing Genomics and Evolutionary Science (HHMI SEA-PHAGES) project to their campus for a meeting for students to share their research work on the isolation and characterization of novel bacteriophages from the environment. This year, Hampden-Sydney students Josh Dimmick ’15, Grayland Godfrey ’15, and Taylor Meinhardt ’16 accompanied Professor Mike Wolyniak to Williamsburg and gave the College’s presentation on Archie14, a Bacillus thuringiensis
bacteriophage discovered by Stephen Woodall ’15 on the H-SC campus.

The SEA-PHAGES program has expanded to include over 70 institutions nationwide and more than 4,800 undergraduates conducting original research on bacteriophage genomics and evolution based out of the University of Pittsburgh. Participating institutions include small liberal arts colleges like Hampden-Sydney, Smith, and Gettysburg and large research universities like Brown, Ohio State, and Washington State working towards a common research goal of a better understanding of bacteriophage diversity. In Virginia, the SEA-PHAGES project is done at Hampden-Sydney, William and Mary, Mary Washington, James Madison, Virginia Commonwealth, and Old Dominion.

The biology department was well represented at the College’s 2015 Final Convocation ceremony, held each April to honor the achievements of members of the Hampden-Sydney community over the past year. The Biology Department gives two awards at this event. The first, the R.T. Hewitt Biology Award, is given to the graduating senior who has distinguished himself in his work in the classroom and the laboratory over his 4 years at the College. This year’s recipient, Davis Carter ’15, has worked extensively with Professor Rachel Goodman over the past two years on research in virology and herpetology and is beginning a research position at the University of Tennessee this summer as the first step towards a career in ecology research.

Finally, Professor William Shear celebrated his retirement at the end of the academic year by receiving the John Peter Mettauer Award for Research Excellence for the fourth time in his 41-year Hampden-Sydney career. Professor Shear has authored 205 papers on a variety of topics including insect taxonomy and evolution and ranks among the most prolific researchers in the 240 year history of the College.

The students in Prof. Werth’s Biology 343 traveled to the Middle Peninsula of Virginia to check out various sites where farmed oysters are bred and raised at a hatchery and then grown in cages in natural habitats. First they visited the Rappahannock Oyster Company on Locklies Creek in Topping, VA, where student Jamie Howard works with other ROC employees. They toured a facility and spoke with staff who farm Crassostrea virginica
, the local oyster, whose populations nearly collapsed in recent decades. Now, baby oysters are placed in cages and grown in various regions where differences in salinity and other aquatic factors cause oysters of each place to develop different tastes. Each year, the Rappahannock Oyster Company grows millions of oysters, selling them locally and shipping them around the world. Students saw the boats, tanks, cages, and other equipment used by the ROC aquaculture operation, and discussed the ecology of the species that so many people like to eat.

Next, the class drove to the Oyster Seed Holding Company on Gwynn’s Island, where sterile triploid oyster embryos are produced from brood stock and where these tiny oysters are raised on different species of “clean” algae that the oysters filter from circulating water. The class discussed many aspects of oyster (and general estuarine) marine biology, particularly the fascinating aspects of algology necessary to grow the algae on which the growing oysters depend. Each year OSH sells millions of spat to companies (like ROC) that culture them until the oysters are large enough to be harvested and eaten. The class learned a lot about the life of oysters and this species’ importance to Virginia science, economics, and the restaurant and aquaculture industries.

Dr. Alex Werth gave an invited colloquium lecture to space scientists at NASA-Goddard Space Flight Center in Greenbelt Maryland on evolutionary rates—how quickly or slowly do species evolve, and why?—and the resulting consequences for exobiology (extraterrestrial life). The lecture was spurred by the article Prof. Werth recently published with Prof. Bill Shear in American Scientist
on “living fossils.” If life exists within reach of Earth-based probes—for example, on the watery moons of Jupiter and Saturn—would it evolve by the same mechanisms as life on our planet? What are the problems of studying species over long periods of time, and how might this affect our study of potential life on other worlds? The lecture gave Prof. Werth an opportunity to observe facilities for constructing and testing space probes, as well as to visit with two former Hampden-Sydney astronomy professors (Dr. Hans Krimm and Dr. Don Kniffen, both at H-SC in the 1990s) and their families.

Senior Biology major Stephen Woodall ’15, who presented his Departmental Honors research in March at the 2015 National Meeting of the American Society for Biochemistry and Molecular Biology in Boston, MA, was recently named the recipient of the Thematic Best Poster Award for the conference’s theme on Molecular Mechanisms of Infection and Immunity. Stephen’s poster was selected by theme organizers from among 84 posters in his category for its outstanding research, which involved the genetic engineering of a mouse melanoma cell line for the purpose of evaluating anti-tumor CD8+ T cell immune responses. Stephen’s poster was selected from presentations from graduate students, postdoctoral fellows, and research scientists from around the world. Stephen conducted this research in the laboratory of Elliott Assistant Professor of Biology Dr. Kristian M. Hargadon ’01. He will be attending N.C. State in the fall for a Master’s in Physiology Graduate Program.
The ASBMB annual meeting is recognized for the breadth of the science covered. Held in conjunction with Experimental Biology 2015, the ASBMB sessions and events at this year’s conference represented an unrivaled opportunity to learn about the latest discoveries in the range of subdisciplines that fall under the biochemistry and molecular biology umbrellas.

Travis Goodloe ’15 was recently awarded a Sigma Xi Grant-in-Aid of Research for his summer research project that he will be conducting in collaboration with Elliott Asisstant Professor of Biology Dr. Kristian M. Hargadon ’01. Travis will be developing an assay to measure melanoma cell metastasis to tumor-draining lymph nodes, and he will use this assay to investigate the rate of lymph node metastasis by melanomas of differing tumorigenicity. Lymph node metastasis is often associated with immune suppression in melanoma patients, and the assay developed by Travis will therefore be a useful system for investigating factors that regulate the spread of melanomas to regional lymph nodes and for assessing the quality of anti-tumor immune responses in tumor-free versus tumor-involved lymph nodes.
The Sigma Xi Grants-in-Aid of Research (GIAR) program has provided undergraduate and graduate students with valuable educational experiences since 1922. By encouraging close working relationships between students and mentors, the program promotes scientific excellence and achievement through hands-on learning.
Three Hampden-Sydney seniors, Jay Brandt, Chris Ferrante, and Stephen Woodall, recently presented their research work at the annual Experimental Biology (EB) meeting in Boston. EB is a federation of six different biological professional societies and is one of the largest scientific conferences in the world.

Chris Ferrante was the first recipient of the Hampden-Sydney student chapter of the American Society for Biochemistry and Molecular Biology’s travel award, which is available to a Hampden-Sydney biochemist/molecular biologist each year to defray the costs of attending the meeting. All three students participated in two poster sessions, one specifically for undergraduates and one for the general meeting.

Stephen’s work with Dr. Kristian Hargadon examined tumor immunology in a mouse model while Jay and Chris’ work with Drs. Mike Wolyniak and Bill Anderson considered the synthesis of polypeptides to create new forms of antibiotics. All three students plan on attending medical school in the future, with Jay already set to begin at Eastern Virginia Medical School (EVMS) in the fall of 2015 as part of H-SC’s early articulation agreement with EVMS.

It was a big meeting!
On March 24, five Hampden-Sydney College and four Longwood University students were inducted into Sigma Xi, the international honorary scientific research society. Founded in 1886 to honor excellence in scientific investigation and to encourage collaboration among researchers in all fields of science and engineering, the Society now consists of over 500 chapters at academic, industrial, and government research institutions and has nearly 60,000 members in more than 100 countries around the world. The Longwood University/Hampden-Sydney College chapter of Sigma Xi was reactivated in 2013, and the two institutions now alternate hosting an annual Sigma Xi Research Symposium that features a keynote speaker and student poster presentations highlighting recent research activities on both campuses.
