Dr. Daumit’s research is devoted to improving overall health and decreasing premature mortality for people with serious mental illnesses such as schizophrenia and bipolar disorder. 

She has conducted observational studies to determine and convey the burden of physical health problems in this vulnerable population, and was the principal investigator of ACHIEVE, a randomized clinical trial of a behavioral weight loss intervention in psychiatric rehabilitation programs funded by the National Institute of Mental Health (NIMH).

Dr. Daumit is currently leading a randomized trial funded by the National Heart, Lung, and Blood Institute, testing a comprehensive cardiovascular risk reduction program in people with serious mental illness (IDEAL). She is the principal investigator, with Dr. Evins at Massachusetts General Hospital, of a randomized trial of a tobacco smoking cessation program integrating exercise and weight management for people with serious mental illness (TRIUMPH), funded by NIMH. 

Dr. Daumit also is leading a NIMH-funded study to examine Health Homes in Maryland psychiatric rehabilitation programs. She has a Mid-Career Investigator Award in Patient Oriented Research focusing on implementation research from NIMH. Dr. Daumit also completed a fellowship at the NIMH-funded Implementation Research Institute.

Her work bridges mental health and primary care fields, and she works with colleagues and mentors trainees with diverse backgrounds spanning psychiatry, psychology, internal medicine, health policy, physical activity and epidemiology.
