Current Lab Members
Robert (Bob) Ernst, PhD
Robert (Bob) K. Ernst, Ph.D., is a Professor and Chair in the Department of Microbial Pathogenesis in the School of Dentistry and an Adjunct Professor in the School of Medicine. In the fall of 2008, I moved my laboratory from the University of Washington, Seattle, where I was a Research Associate Professor in the Department of Medicine, Division of Allergy and Infectious Diseases and a principal investigator with the Northwest Regional Center of Excellence for Biodefense and Emerging Infectious Diseases Research (NWRCE) to the University of Maryland. I received my B.S. from the State University of New York at Oswego (Biology and Chemistry), an M.A. from SUNY Buffalo (Microbiology), and a Ph.D. from the University of Virginia (Microbiology) studying retroviral RNA transport, where I was also a fellow in the Myles H. Thaler Center for Retrovirus Research. Subsequently, I was a senior fellow at University of Washington in the laboratory of Samuel I. Miller (Allergy and Infectious Diseases) from 1997 – 2002 before joining the faculty in 2002.
