The Grinch Visits H-SC Biology Department

On December 5, the H-SC Biology Department had a special visitor lurking the halls, The Grinch!  During this time, one Professor Hargadon was nowhere to be found, and upon the Grinch’s visit to a Microbiology class, students feared that their Christmas dreams of good grades would be stolen away.  However, they soon realized that, as the story goes, the Grinch’s heart grew 3 sizes at Christmas, and many students were even given the gift of a final exam exemption!

H-SC Biology on the go: presentations in all four corners of the United States

The first two weeks of November saw an unprecedented period of travel activity for the faculty and students of the Hampden-Sydney Biology Department.  Over this period, H-SC biologists attended six regional and national scientific conferences all across the United States and presented the research work they have been doing over the summer as well as the academic year:

American Society for Microbiology Virginia Branch Meeting, Roanoke, VA

At this meeting, Brant Boucher ’17 and James Lau ’17 presented the work they have been doing with Dr. Kristian Hargadon.

The NSF-funded program emphasizes communication with non-scientists. In addition to giving a formal talk, Werth served as a naturalist onboard whale watching cruises and spoke with several groups of college and secondary students plus teachers and the general public. Many groups of feeding whales were seen, along with seals, sea lions, sea otters, and other marine life.


The Hampden-Sydney Biology Department prides itself with providing opportunities for students to work closely with their professors on original research activity.  These meetings provide the opportunity for students to share their work on a regional or national stage and gain valuable scientific communication experience as they hone their career interests.

Biology student research in action: student research on hops development presented at local brewing festival

Over the past couple of years, several students in the Hampden-Sydney biology classroom and laboratory have explored the microbes that coexist on hops plants and how those microbes may help or harm commercial hops yields.  The project has been integrated as an authentic research experience in the Biology Department’s Introductory Biology course and has served as the inspiration for several independent student projects that have taken place both during the academic year and over the summer.  One of the most dedicated students to this project has been Michael Willis ’17, who is looking towards a career in the brewing industry after graduation.  Michael recently took a selection of research posters detailing the work done by Hampden-Sydney students on plant/microbe interactions involving hops and presented them at the Hops and Harvest Festival at Pocahontas State Park in Chesterfield, VA.

The Hops and Harvest Festival is the premier craft beer festival in central Virginia, and dozens of visitors took the time to look over the variety of posters detailing how common plant pathogens may be affecting the ability to grow a strong commercial hops crop in Virginia.  This presentation is an outstanding example of how student research at Hampden-Sydney can have real world applications that can benefit the general public.

Wildlife Biology class takes weekend trip to Eastern Shore


Dr. Goodman’s BIOL 385 Wildlife Biology class took a weekend field trip in October to the Eastern Shore Birding & Wildlife Festival.  We camped for 2 nights in Kiptopeke State Park and went to workshops in bird identification and bird watching for  the ornithology portion of the course.


The Delmarva peninsula is an amazing location for watching birds in the migration season, because birds flying south and funneled to the tip as they attempt to stay over land for as long as possible before crossing water.  The park we stayed in has a “Hawk Watch” there people sight and count birds of prey as they fly unidirectionally overhead- typically they see over 1,000 hawks daily!


In total, we saw and heard 40 species of birds (and some bottle-nosed dolphins). We also hear a fascinating keynote lecture by a scientist with the American Bird Conservancy about the status of birds and their habitats, and the history and progress of bird conservation since the Migratory Bird Treaty Act of 1918.

James Lau ’17 Recognized for Research on Melanoma

Senior Biology major James Lau ’17 recently received the Best Poster Award for a poster presentation of his research at the 4th Annual Longwood University/Hampden-Sydney College Sigma Xi Research Symposium.  The symposium featured a talk by keynote speaker Dr. Steve Cresawn of James Madison University and was highlighted by a student poster presentation featuring 22 undergraduate researchers from both Longwood University and Hampden-Sydney College.  James, who was recently named only the 3rd Goldwater Scholar in the history of H-SC, presented research he has been conducting in collaboration with Elliott Associate Professor of Biology Dr. Kristian M. Hargadon ’01.  James began working in Dr. Hargadon’s laboratory in the summer of 2016 on a project designed to investigate the role of the Foxc2 gene in regulating the progression of melanoma, the most aggressive form of skin cancer.  James is continuing his research with Dr. Hargadon throughout his senior year for his Departmental Honors project, which is focused on assessing how expression of the FOXC2 transcription factor regulates tumor migration and invasion within tissues, key processes that ultimately contribute to tumor metastasis.  Following his graduation, James will be attending medical school at Eastern Virginia Medical School, where he was accepted as a sophomore through the College’s Early Admission Program with EVMS!

Elliott Associate Professor of Biology Dr. Kristian M. Hargadon ’01 Publishes Major Review Article on TGFb1 and Cancer

Elliott Associate Professor of Biology Dr. Kristian M. Hargadon ’01 recently published a major review article on the role of TGFb1 in compromising the quality of anti-tumor immune responses. Following a recent publication by Dr. Hargadon and collaborating Hampden-Sydney College students in the journal Immunology and Cell Biology, which described TGFb1’s alteration of dendritic cell function in melanoma, Dr. Hargadon was invited by editors of the Journal of Clinical Medicine to submit a comprehensive review article on TGFbeta1’s influence on the anti-tumor immune responses. Dr. Hargadon’s article, entitled “Dysregulation of TGF1 Activity in Cancer and Its Influence on the Quality of Anti-Tumor Immunity” appears in the Journal of Clinical Medicine’s Special Issue dedicated to the topic “Biological and Clinical Aspects of TGF-beta in Carcinogenesis.” Dr. Hargadon’s article highlights current understanding in the field of tumor-associated TGFb1’s ability to compromise the function of several immune cell populations, including dendritic cells, T cells, macrophages, and neutrophils, and it highlights how our knowledge of TGFb1’s immunosuppressive mechanisms is being translated into novel immune therapies in the clinical setting. This article can be found at the following link: http://www.mdpi.com/2077-0383/5/9/76

Ongoing research in Dr. Hargadon’s laboratory at Hampden-Sydney College is focused on understanding immune suppression by melanoma and elucidating the function of genes that promote melanoma progression. Since returning to his alma mater in 2009, Dr. Hargadon has involved 12 Hampden-Sydney College students in independent research projects related to this work, and he has incorporated aspects of his research into his Biology 201 Genetics and Cell Biology course, where 15-20 students are involved in melanoma research each year that he offers the course.

Welcome Dr. Kristin Fischer to the H-SC Biology Department

Dr. Kristin M. Fischer is very excited to return to her home state of Virginia and be the newest member of the H-SC Biology department. She earned her B.S in Biology at Virginia Tech and her interest in the medical field led her to pursue her graduate degrees from the Virginia Tech-Wake Forest School of Biomedical Engineering and Sciences. Dr. Fischer focused on tissue engineering with the goal to replace or repair damaged tissue in the body by creating a scaffold structure for cells to grow on, culturing cells on the scaffold, and implanting a functional, new tissue into a patient.


Her graduate work at Virginia Tech and post-doctoral work at Rutgers University focused on creating a scaffold for skeletal muscle cells to grow on and culturing the skeletal muscle cells on it. The image below shows a scanning electron image of the polymeric scaffold on top and skeletal muscle cells fluorescently stained grown on it below. She completed a second postdoctoral position focusing on cardiac muscle tissue engineering at the Massachusetts Institute of Technology. In addition to her research, Dr. Fischer has previously taught a variety of courses including physiology, tissue engineering, anatomy & physiology, and introductory biology. She is looking forward to teaching in the upcoming school year.

A summer of molecular developmental neurobiology by Tyler Reekes ’17

This summer I am working with Dr. Clabough to identify a number of proteins that are vital to brain and neuronal development and may be affected by ethanol exposure. We are using a Fetal Alcohol Spectrum Disorders (FASD) mouse model and have chosen a paradigm that mimics a human third-trimester binge drinking session. Many FASD mouse models demonstrate neuronal deficits that persist into adulthood, though the specific actions of ethanol on the development of the nervous system are still not well understood, especially immediately after the ethanol exposure.

We have isolated protein from FASD and control mouse brains. We are using Western Blotting techniques to isolate specific proteins, such as Huntingtin, Brain Derived Neurotrophic Factor (BDNF), RE1-Silencing Transcription factor (REST), also known as Neuron-Restrictive Silencer Factor (NRSF), and others. We are using densitometry on ImageJ software to determine the relative concentrations of these specific proteins in important brain areas, such as the striatum and cortex.



We are hoping to find changes in the expression of these genes 24 hours after ethanol exposure, and possibly a molecular correlate to a changed striatal neuronal branching that we have also observed at this early time point. The branching of these neurons is of major concern so these neurons connect to transmit signals properly. Therefore, a change in neuronal branching may translate into a similar change in behavioral, motor, or overall cognitive function that can be seen in live models.   

I have learned much about basic protein extraction and procedures by running Western Blots and interpreting results. The most important thing I have learned from this summer, is that Westerns rarely work. However, the problem solving skills I have learned from this have made me a better biologist and student in general. I cannot express my gratitude to both Dr. Clabough for all that she has taught me, but also to the Honors Council for allowing me to complete this research.
