Harry Reyes Nieva, MPhil, MAS, MA
Postdoctoral Research Scientist

Columbia University Irving Medical Center
Harry Reyes Nieva is a biomedical informatician and postdoctoral research scientist in the Division of Infectious Diseases at Columbia University Irving Medical Center. Reyes Nieva has been an active member of the OHDSI community since 2019, including his work on the Health Equity Research Assessment (HERA) network study, a systematic large-scale characterization of intersectional health disparities (e.g., across race, gender, and age). He currently serves as co-lead of the OHDSI Early-Stage Researchers Workgroup.
Building on two decades of domestic and international experience in clinical and public health informatics, Reyes Nieva’s research focuses on human-centered artificial intelligence (AI) and development of systematic, scalable, data-driven approaches that advance health equity science. He is particularly interested in using, interrogating, and expanding the vast toolbox that computational learning (e.g., machine learning, natural language processing, spatiotemporal analysis) offers to better understand, improve, and facilitate study of health in populations and communities that are marginalized. His work often links multimodal data on thousands to hundreds of millions of individuals and derives novel insights by mining biomedical literature, broad population-level sources (e.g., national claims, open government datasets, public health reporting), clinical data warehouses (e.g., electronic health record, health information exchange, and biobank data), and primary data collected for clinical trials and national surveys.
Prior to Columbia, Reyes Nieva held a number of clinical research and public health positions at Brigham and Women’s Hospital, Harvard Medical School, and the Harvard T.H. Chan School of Public Health, including the Strategic Information division of the U.S. President’s Emergency Plan for AIDS Relief (PEPFAR) at Harvard University which aimed to rapidly expand antiretroviral therapy for people living with HIV/AIDS in Botswana, Nigeria, and Tanzania.
Reyes Nieva has a Bachelor of Arts in Sociology and History from Yale University, Master of Applied Science in Spatial Analysis from the Johns Hopkins Bloomberg School of Public Health, and a PhD in Biomedical Informatics from Columbia University. During his PhD, he was also a Visiting Postgraduate Research Fellow in the Department of Medicine at Harvard Medical School.
