Dr. Kuhs earned her Ph.D. in biomedical sciences from the University of Pennsylvania School of Medicine in 2011. Working with Dr. David B. Weiner, her doctoral research focused on the design and development of novel hepatitis C virus DNA vaccines able to induce potent T cell-based immunity within the liver. In May 2012, Dr. Kuhs earned an M.P.H. from Johns Hopkins University with a concentration in epidemiology and biostatistics. Dr. Kuhs’ research interests include the natural history of cancer-causing viruses and prevention of cancer through prophylactic vaccination against oncogenic viruses. Dr. Kuhs is working with Aimée R.
