A major advantage to being a faculty member at a small liberal arts college is the ability to work directly with undergraduate students. As Dean of Student Success and Degree Completion, I work at the interface between students and the faculty and staff of UVA Wise. My objectives are to ensure each student has access to the resources necessary to achieve both their academic and career goals. I strongly support individual student mentorship and work with students as they develop a sense of ownership in their educational experience.
As a classroom educator I value assisting students in their exploration of various scientific disciplines, and providing novel frameworks for their growth and development into the next generation of scientists and leaders. My first goal as an educator is to help students develop a firm understanding of the molecular nature of living systems. My second goal is to assist students in becoming scientific communicators. As such, reading and critical review of primary scientific literature, preparation of mock-manuscripts, and public presentation of scientific topics play a major role in my curricula.

The National Cancer Institute at the National Institutes of Health estimates >70% of all human cancers result from exposure to environmental carcinogens. Many environmental carcinogens damage DNA and cause mutation, genomic instability, and ultimately disease. Therefore, understanding how cells respond to these environmental insults is of critical importance to developing cancer treatments and prevention policies. My long-term research interests focus on determining how protein-protein and protein-DNA complexes are assembled and remodeled to repair damaged DNA. Understanding how these molecular machines are spatially and temporally organized is critical to elucidating their functions in biochemical pathways. Moreover, as many current anti-cancer agents act by inducing DNA damage, knowledge of the molecular mechanisms underlying DNA repair has the potential to provide new therapeutic strategies to enhance or improve upon current chemotherapies.
I strongly support and encourage research opportunities for undergraduate students. Research in my laboratory provides an exciting training environment for young scientists. Students actively participate in experimental design, data acquisition and analysis. Program objectives are planned to allow for the research to progress in stages, providing adequate time for training students in necessary skills. I am a molecular biologist with broad training ranging from cellular biology, biochemistry, and structural biology. In my laboratory, we employ a wide variety of technologies to answer these questions. In order to test how molecular machines function, we isolate repair proteins for biochemical, biophysical, and ultimately structural analysis of their machines. We then use recombinant genetic systems in human cell cultures to verify and validate the results we obtain via biochemical analysis. I maintain an open-door policy for all members of my laboratory and establish regularly scheduled meetings with each individual student to develop and assess progress towards academic, research, and career goals.
