Chelsea Messinger, MD, PhD

Anesthesiology Resident · Massachusetts General Hospital

I am an anesthesiology resident at Massachusetts General Hospital, a research collaborator at CAUSALab at the Harvard T.H. Chan School of Public Health, and an editorial fellow at the British Journal of Anaesthesia.

My research uses epidemiologic and causal inference methods to study clinically actionable questions in perioperative care.

I completed my MD at Harvard Medical School and my PhD in Epidemiology at the Harvard T.H. Chan School of Public Health. Previously, I graduated from Yale College and completed a Fulbright research fellowship in Malaysia.
