Biography
Dr. Landry graduated from Georgetown University School of Medicine, received her internal medicine residency training at Yale New Haven Hospital, and completed fellowships in Infectious Diseases and Clinical Virology (Laboratory Medicine) at Yale University. She is board certified in Internal Medicine and Infectious Diseases but has focused her career on the field of diagnostic virology.
Under Dr. G.D. Hsiung, she helped to establish the national Virology Reference Laboratory at VA Connecticut, and subsequently established the Clinical Virology Laboratory within the Department of Laboratory Medicine at Yale New Haven Hospital, one of the premier virology laboratories in the U.S. She has over 200 publications on diagnostic testing, and has been the Virology Volume Editor for the Manual of Clinical Microbiology from ASM Press from the 9th to the 13th edition and is Co-Editor in Chief for the 14th edition. She serves as the main teacher of Medical Virology for Yale medical students, and as Vice Chair for Quality and Safety Laboratory Medicine.
Dr. Landry’s interests focus on the rapid detection and quantitation of viruses for clinical diagnosis and the impact of new test methods on patient management.

Clinical Care
Overview
When she thought about what she’d like to do as a doctor, Marie Louise Landry, MD, originally intended to care for patients in the developing world. Instead she ended up in the lab, diagnosing viral diseases. “I meant only to learn about viruses to inform my infectious disease training, not make virology the focus of my career, but the need and opportunity presented themselves,” Dr. Landry says.
Dr. Landry is board-certified in internal medicine and infectious diseases, but has focused most of her work on the burgeoning field of diagnosing and detecting viruses. She enjoys working in a field where things are always changing and the pace is ever faster. “When I started in virology, tests could take weeks to complete, there were no treatments and the laboratory phone never rang. Now we have clinicians calling all day and even in the middle of the night wanting virology tests,” Dr. Landry says.
Dr. Landry is a professor of laboratory medicine and of infectious disease medicine at Yale School of Medicine.
