Krishna Reddy, MD, MS Laboratory

Research Interests

Krishna Reddy, MD, MS, studies tobacco, HIV and tuberculosis, both individually and in combination. Along with colleagues in the Medical Practice Evaluation Center at Massachusetts General Hospital, he applies methods of simulation modeling, epidemiology and cost-effectiveness analysis to study clinical and economic outcomes in the U.S. and other countries. The goal of his research program is to provide evidence- and model-based approaches to clinical decision-making, trial design and public health policy.
