Marie Landry, MD


Infectious Disease, Internal Medicine

Conditions & Treatments

Infections, Viral Infections


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.
