Maria Merritt is a core faculty member of the Johns Hopkins Berman Institute of Bioethics, where she co-leads the Hecht-Levi Postdoctoral Fellowship Program. She serves on the IRB at the Johns Hopkins Bloomberg School of Public Health.

A major objective of Dr. Merritt’s current research, in collaboration with colleagues, is to develop a novel methodology for considering social justice impacts side-by-side with cost-effectiveness as part of economic evaluation in health policy. Dr. Merritt’s other areas of scholarly interest include the ethics of public health research in LMICs – particularly questions about researchers’ responsibilities to benefit research participants and populations – and moral psychology, the study of feeling, thought, and action in morally significant contexts.
