Hari B. Keshava, M.D., is Health Sciences Assistant Clinical Professor in the Department of Surgery, Division of Thoracic Surgery at the University of California, Irvine School of Medicine and Chief of Thoracic Surgery at the Veterans Administration Health System in Long Beach, California. He completed his general surgery residency at Cleveland Clinic, a thoracic surgery research fellowship at Yale/New Haven Hospital, and a cardiothoracic surgery fellowship at Memorial Sloan Kettering Cancer Center/Weill-Cornell Medical Center. Keshava received his M.D. from Case Western Reserve University School of Medicine, along with a Master of Science in Medical Device and Diagnostic Engineering and a Bachelor of Science in Electrical Engineering from the University of Southern California.
Keshava's clinical and research focus centers on lung cancer screening, early-stage lung cancer treatment, and health disparities in thoracic oncology. He serves as principal investigator on multiple clinical trials and research initiatives, including a Merck/Moderna Phase 3 trial evaluating adjuvant immunotherapy in resected non-small cell lung cancer and an investigator-initiated trial examining lung cancer screening in family members of patients with mutation-driven lung cancer, supported by $300,000 from UCI's Health Disparity Research and Interventions program and $100,000 from The Kenneth T and Eileen L. Norris Foundation. His work has been published in journals including the Journal of Thoracic and Cardiovascular Surgery, Annals of Thoracic Surgery, and World Journal of Surgery.
Keshava has held numerous leadership positions within professional organizations, including Chair of the University of California Lung Cancer Consortium, Chair of the American College of Surgeons Resident and Associate Society Education Committee, and member of the Society of Thoracic Surgeons Workforce on General Thoracic Surgery. He serves on multiple institutional committees at UCI, including the School of Medicine Admissions Committee and the Department of Surgery Wellness Officer.
