Keynotes

A highlight of the Annual Meeting experience, the keynote speakers bring bold ideas and fresh insights based on their own personal experiences of cancer diagnosis.

Keynote 01: My Brain Tumor: Why I got Better Care than My Neighbors
Monday, September 29  |  9:15 a.m. - 10:15 a.m.

Bobby Mukkamala, MD, is a board-certified otolaryngologist and head and neck surgeon in solo, private practice in Flint, Michigan. He currently serves as president of the American Medical Association (AMA) and has been active in the AMA since his residency. Dr. Mukkamala graduated from the University of Michigan Medical School before completing his residency at Loyola University Medical Center in Chicago. A past recipient of the AMA Foundation’s “Excellence in Medicine” Leadership Award, Dr. Mukkamala was elected to the AMA Council on Science and Public Health in 2009 and served as chair from 2016 to 2017. From there, he was elected to the AMA Board of Trustees in both 2017 and 2021. He has also been a member of the Michigan State Medical Society Board of Directors since 2011, and past president of the Genesee County Medical Society (GCMS) where he continues to serve on the board. He shares an office with his wife, Nita Kulkarni, MD, an obstetrician-gynecologist. Together, they established the Endowed Health Professions Scholarships at the University of Michigan, Flint, in 2012. Dr. Mukkamala was diagnosed in 2024 with a grade 2 glioma after experiencing aphasia at an AMA meeting.

As AMA President, Dr. Mukkamala will discuss his recent brain cancer diagnosis, what his experience says about health gaps in America, and what he’s learned about being a doctor by being a patient. He’ll also lay out solutions to improve access to care, steps necessary to expand the physician workforce, and highlight the work of the American Medical Association to confront concerning public health trends.

Keynote 02: Hope, Research, and the Cancer Patient
Tuesday, September 30  |  9:00 a.m. - 10:00 a.m.

Bryant Lin, MD, MEng, is a primary care physician, educator and researcher. The cornerstone of Dr. Lin’s work is keeping medicine focused on humans — patients, providers, families and trainees — and not lost in technology and algorithms. His clinical focus is internal medicine, consultative medicine, preventive health, chronic care management, Asian health, and atrial fibrillation. After receiving his undergraduate and master’s degrees in electrical engineering and computer science from MIT, he completed his MD and Internal Medicine training at Tufts University School of Medicine and Tufts Medical Center. Since completing his post-graduate training, he stayed at Stanford as clinical faculty in Primary Care and Population Health in the Department of Medicine where he has invented and researched new medical technologies addressing unmet human-centered needs and started the Consultative Medicine Clinic evaluating patients with medical mysteries. He served as the Training Director for the Joe and Linda Chlapaty DECIDE Center which has created a novel shared decision-making tool for atrial fibrillation anti-coagulation and is an investigator in several active clinical trials. In 2018, he co-founded and currently co-directs, with Latha Palaniappan, MD, MS, the Center for Asian Health Research and Education (CARE) which aims to improve the health of Asians everywhere. In 2021, he was appointed the Director of Medical Humanities and Arts at Stanford. Dr. Lin was diagnosed with Stage 4 Lung Cancer (non-small cell lung cancer) in 2024 and started a Stanford Medical School course centered around his case. Using examples from his own Stage 4 Lung Cancer Case, Dr. Lin will discuss the importance of research and hope from the perspective of a cancer patient and academic researcher.
