Dr. Juan Wisnivesky is a clinical epidemiologist whose research focuses on chronic lung disease, such as asthma and chronic obstructive pulmonary disease (COPD), cancer epidemiology and outcomes research, and long-term outcomes of Covid-19. He is the System Chief of the Division of General Internal Medicine at Mount Sinai. He has led several studies evaluating determinants of self-management, outcomes, and disparities in care of patients with chronic lung diseases. Currently, he is PI of multiple R01-funded studies evaluating symptoms perception and asthma self-management in the elderly, self-management of COPD in patients with comorbidities, and investigating the biologic and behavioral pathways linking depression with asthma self-management behaviors and outcomes. Since 2020, Dr. Wisnivesky has been leading the Mount Sinai Health System Post-Covid-19 Registry, assessing the long-term outcomes of Covid-19 patients. His work has also been related to lung cancer treatment in the elderly and disparities in care. He has been involved in several projects involving SEER-Medicare data and other large cancer registries. He published several manuscripts using population-based cancer registries addressing issues related to screening, diagnosis, treatment, disparities in care and outcomes of patients with lung cancer. In the past, he led 3 R01s evaluating staging and treatment of lung cancer using the SEER-Medicare registry and a 4-site cohort study funded by the American Cancer Society to study disparities in lung cancer care. He has been the primary mentor of 9 junior faculty with externally funded career development awards. He is also MPI of an NCI T32 program in Cancer Prevention and Control in Priority Populations.
