Elliott Associate Professor of Biology Dr. Kristian M. Hargadon ’01 Receives Invitation for Membership in European Academy of Tumor Immunology

Elliott Associate Professor of Biology Dr. Kristian M. Hargadon ’01 was recently invited to become a member of the European Academy of Tumor Immunology by the Academy’s Governing Body.  Founded in 2011  to promote tumor immunology at the scientific and clinical levels, the European Academy of Tumor Immunology (EATI) aims to “bridge fields, bridge continents, and bridge generations” of tumor immunologists across the globe who are studying tumor immunity at fundamental, translational, and clinical levels.  With his membership in EATI, Dr. Hargadon, whose research at Hampden-Sydney College focuses on immune suppression by melanoma, joins an international group of 360 tumor immunologists that includes 3 Nobel Laureates and many of the leading cancer researchers in the world.

Elliott Associate Professor of Biology Dr. Kristian M. Hargadon ’01 Receives $100,000 Grant for Cancer Research

Elliott Associate Professor of Biology Dr. Kristian M. Hargadon ’01 was recently awarded a $100,000 grant from the Jeffress Trusts Awards Program in Interdisciplinary Research to support his melanoma research program.  Funds from this grant will be used by Dr. Hargadon and his collaborating Hampden-Sydney College students to investigate anti-tumor CD8+ T cell dysfunction and the ways in which lymph node invasion by melanoma impacts the quality of tumor-specific CD8+ T cell immune responses.  Understanding these processes will shed light on mechanisms by which tumors evade immune destruction, and this knowledge may ultimately inform the design of novel immunotherapies that aim to improve the quality of anti-tumor immunity.

Biology students, faculty recognized for excellence at H-SC 2016 Final Convocation

The biology department was well represented at the College’s 2016 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, Christopher Hawk ’16, has worked extensively with Professors Ed Lowry and Mike Wolyniak over the past two years on ecological and molecular biological research studying the microbiome of hops.  His work was instrumental in the development in a new research-based introductory laboratory course at Hampden-Sydney.  Chris plans to begin work next year in the field of environmental consulting.

H-SC Biology students present research at national conferences coast-to-coast

One of the benefits of getting involved in independent research at Hampden-Sydney is the chance to present the finished product at a national scientific conference.  In the course of a week in early April 2016, six H-SC biology students presented their research on both coasts of the United States!  First, four students made their way to San Diego, California, to attend the 2016 Experimental Biology Meeting.  Travis Goodloe ’16 and Jefferson Thompson ’16 presented work done last summer under the guidance of Dr. Kristian Hargadon while Charlie Kyle ’16 and Jake Rockenbach ’16 showed a poster based on their joint Departmental Honors project advised by chemist Dr. Bill Anderson and biologist Dr. Mike Wolyniak.

10 H-SC Students Inducted into Sigma Xi Honor Society

On March 30, ten Hampden-Sydney College 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.  Congratulations to the H-SC students inducted in 2016:  Branch Vincent, Christopher Hawk, J.D. Chaudhry, Jefferson Thompson, Linh Nguyen, Mitchell Thomas, Shaquann Seadrow, Will Echols, Will Fitzgerald, and Zachary Martin.

Hampden-Sydney genomics students publish their annotated bacteriophage sequence on national database

As the final product of the Hampden-Sydney Genomics and Bioinformatics course from the spring 2014 semester, the National Center for Biotechnology Information has accepted  the class’ sequence annotation of a bacteriophage discovered at Hampden-Sydney for publication in the GenBank database.  The sequence, authored by Josh Dimmick ’15, Grayland Godfrey ’15, William Banning ’15, Mitch Cavallarin ’15, Tommy Isom ’14, Hakeem Mohammed ’14. Jackson Parker ’14, Francis Polakiewicz ’14, Putney Smith ’14, and Professor Mike Wolyniak, was a part of Hampden-Sydney’s participation in the Howard Hughes Medical Institute (HHMI) Science Education Alliance-Phage Hunters Advancing Genomics and Evolutionary Science (SEA-PHAGES) program.  Dr. Vassie Ware of Lehigh University collaborated with the final stages of preparing the sequence, which will directly contribute to a national research initiative based out of the University of Pittsburgh that seeks to understand how viruses that infect various bacterial species have evolved over time.

Bacteriophage McFly was isolated by a previous Hampden-Sydney Molecular and Cellular Biology course by Seth Ayers ’11.  It is a virus that infects the species Mycobacterium smegmatus and has a genome of approximately 50,000 basepairs.  The student authors listed above used several bioinformatics databases over the course of a semester to identify and characterize the predicted genes in the McFly sequence.  McFly is the third bacteriophage Hampden-Sydney students have contributed to the national sequence database, joining Arturo and Cheetobro.  The SEA-PHAGES initiative allows students from Hampden-Sydney to join undergraduates from across the nation in conducting original research as a component of their scientific training.

Dr. Kristian M. Hargadon ’01 Introduces Cancer Research into the Undergraduate Laboratory, Publishes Novel Approach for Undergraduate Investigation of Gene Expression

Associate Professor of Biology Dr. Kristian M. Hargadon ’01 recently published an article in the journal Biochemistry and Molecular Biology Education highlighting a novel laboratory module that he developed for improving undergraduate student learning of gene expression.  This module, which is based on Dr. Hargadon’s research interests relating to melanoma, is currently used in his Biology 201 Genetics and Cell Biology course and teaches students several cutting edge techniques for investigating gene expression.  Specifically, over a 6-week period, students are exposed to both traditional and quantitative polymerase chain reaction technologies as well as flow cytometric assays as they investigate expression of the Tgfb1 gene in highly versus poorly tumorigenic melanomas at both the population and single-cell levels.  In the recently published study, Dr. Hargadon demonstrates the utility of this module in improving student learning of not only the process of gene expression but also of research techniques that may be employed for the experimental analysis of gene expression.  Since publication of this article, Dr. Hargadon has extended this laboratory exercise in his class such that upon completion of the module, students then develop their own cancer research projects in which they assess expression of a unique gene of interest that they hypothesize might contribute to melanoma progression through altered expression patterns.  Also since its publication, Dr. Hargadon’s laboratory module has also been implemented in a 300-level Biochemical Methods course at Bucknell University.

Travis Goodloe ’16 Receives Award for Cancer Research

Senior Biology major Travis Goodloe was recently awarded 1st Place in the poster competition for research he presented at the 2015 VA Branch Meeting of the American Society for Microbiology.  Travis’ research, which he conducted in the laboratory of Associate Professor of Biology Dr. Kristian M. Hargadon ’01, involved the development of a quantitative RT-PCR-based assay for detecting metastatic melanoma cells in tumor-draining lymph nodes.  His study provides a framework for future research aimed at investigating factors the promote lymph node invasion by melanoma, and the assay he developed may ultimately provide a useful diagnostic tool for assessing melanoma progression.  Travis’ poster earned the top honor from among 59 research posters presented by both undergraduate and graduate students from colleges and universities throughout the state.  Travis will attend medical school at the University of South Alabama following his graduation in 2016.
