Krishna P Reddy, M.D.


Dr. Reddy studies tobacco, HIV, and tuberculosis, both individually and in combination. He applies methods of simulation modeling, epidemiology, and cost-effectiveness analysis to study clinical and economic outcomes in the US and other countries. The goal of his research is to provide evidence- and model-based approaches to clinical decision-making and public health policy.

Available: 01/10/22, Expires: 08/31/25

The projects entail using methods of decision science, clinical epidemiology, and cost-effectiveness analysis to study the intersection of tobacco, HIV, and TB, both in the US and in South Africa. The goal of the research is to inform clinical practice and public health policy.

PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
