Biography
Craig Roy received his B.S. from Michigan State University in 1985 and earned his Ph.D. in Microbiology and Immunology at Stanford University in 1991 in the laboratory of Dr. Stanley Falkow. After completing a postdoctoral fellowship with Dr. Ralph Isberg in the Department of Molecular Microbiology at Tufts University School of Medicine in 1996, he was appointed as an Assistant Professor in the Department of Molecular Genetics and Microbiology at Stony Brook University. Dr. Roy became a founding member of the Department of Microbial Pathogenesis at Yale University in 1998 and serves as Vice-Chair. He currently holds the title of Waldemar Von Zedtwitz Professor of Microbial Pathogenesis and Immunobiology. Research in the Roy laboratory focuses on the host-pathogen interface. Using multi-disciplinary approaches his laboratory has discovered many novel mechanisms that intracellular pathogens use to modulate host membrane transport pathways, which allow these pathogens to evade cell autonomous defenses and create novel organelles that permit bacterial replication.
