Physician Biography

I completed my MD and PhD training at Yale School of Medicine, and, after completing residency and fellowship training in Clinical Pathology and Medical Microbiology, respectively, at Yale-New Haven Hospital, I joined the faculty in the Department of Laboratory Medicine at Yale School of Medicine in 2011.

I currently serve as the Director of the Medical Microbiology Laboratory at Yale-New Haven Hospital and the Director of the Virology Reference Laboratory at the West Haven Veteran's Administration Hospital. These laboratories perform complex and comprehensive testing for bacteria, mycobacteria, yeast, molds, parasites, and viruses for patients and veterans in Connecticut and New England. The clinical laboratories at Yale and Yale-New Haven Hospital employ state of the art testing overseen by full-time clinical pathologists. The field of infectious disease diagnostic testing is rapidly evolving, and my academic and professional efforts are dedicated to understanding the complexities of testing as well as moving the field forward with new technology and the development of laboatory best practices.
