Message from Dean Cooley - New BBS Director Appointed

September 18, 2019

Dear BBS colleagues,

It gives me great pleasure to announce the appointment of Professor Craig Roy as the new director of the Combined Program in the Biological and Biomedical Sciences (BBS), effective September 1, 2019, for a five-year term. I am very grateful to Professor Roy for taking on this important leadership position.

Craig brings to this position deep experience as a long-time leader in the Microbiology track of the BBS as the Director of Admissions and Director of Graduate Studies, and as a member of the executive committees for both the Immunobiology and the Microbial Pathogenesis training grants. His collaborative and consensus-building leadership style suits him perfectly to take the BBS into its next phase of development and growth.

The Waldemar Von Zedtwitz Professor of Microbial Pathogenesis and Immunobiology, Craig came to Yale in 1998 and was a founding member of the Department of Microbial Pathogenesis, of which he now serves as Vice-Chair. Roy earned 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 Assistant Professor in the Department of Molecular Genetics and Microbiology at Stony Brook University.

Research in the Roy laboratory focuses on the host-pathogen interface. Using multi-disciplinary approaches his laboratory targets the molecular and cellular events that enable microbial pathogens to evade host defense mechanisms. In particular, Craig studies how bacteria that replicate inside mammalian cells create specialized vacuoles that support pathogen replication. They have used Legionella pneumophila and Coxiella burnetii as model pathogens to study this process. The goals of this research are to determine the mechanism by which these bacterial effector proteins regulate phagosome maturation, modulate host immunity, and subvert eukaryotic cell functions.

I want to take this opportunity to express my heartfelt thanks to Professor Tony Koleske who has led the BBS with impressive dedication and diplomacy for the last five years. During his term, Tony has expanded the CSC-Yale World Scholars Program, enabling us to bring an increasing number of talented Chinese graduate students to our campus, and has established the new CAPES-Yale Scholars Program with support from the government of Brazil. In collaboration with our M.D./Ph.D. program, he has also built substantially our undergraduate pipeline for doctoral programs in the life sciences.

Please join me in congratulating Craig on his new role. I know he looks forward to working with the program’s faculty, staff and students to continue Yale’s commitment to excellence in the biological and biomedical sciences.
