Dr. Manrai's research group works broadly on two areas:

  1. Statistical and machine learning approaches to improve medical decision making
  2. Meta-science (“science of science”) approaches to model and enhance reproducibility of integrative molecular, clinical, and environmental studies, particularly in the increasingly common setting of communal investigation of large, shared datasets.

A major long-term goal of Dr. Manrai's work is to improve the use of genomic and laboratory data in diagnosing and treating inherited heart disease across demographically diverse populations. Dr. Manrai's research has been published in the New England Journal of Medicine and JAMA, presented at the National Academy of Sciences, and featured in the Wall Street Journal, New York Times, and NPR.


Arjun (Raj) Manrai is an Assistant Professor at Harvard Medical School and Faculty Member in the Computational Health Informatics Program (CHIP) at Boston Children’s Hospital, where he directs the Laboratory for Probabilistic Medical Reasoning.

Manrai received an A.B. in Physics with Highest Honors from Harvard and earned his Ph.D. in Bioinformatics and Integrative Genomics from the Harvard-MIT Division of Health Sciences and Technology.
