I am a tenured professor of microbial sciences with an interdisciplinary appointment at Columbia University Medical Center and the Vagelos College of Physicians & Surgeons.

Academic Appointments

  • Professor of Microbial Sciences (in Dental Medicine and Microbiology and Immunology, Obstetrics and Gynecology and Medical Sciences in Medicine)


My research has been consistently funded by the NIH and involves the role of microbes in human health and disease. My research interests include host-pathogen interactions, human microbiome and oral-systemic connections. The human microbiome is a vast population of microbes that play an essential role in health and disease. Work in our laboratory is focused on the following aspects: (i) investigating the role of oral bacteria in extra-oral infection and inflammation; (ii) investigating the mechanisms of Fusobacterium nucleatum pathogenesis in pregnancy complications and gastrointestinal cancers; and (iii) developing genetic tools for mutant construction in bacteria.
