Nipavan Chiamvimonvat, MD
Dr. Chiamvimonvat, the chair of the Department of Basic Medical Sciences at the University of Arizona College of Medicine – Phoenix, is a physician scientist whose career has been dedicated to treating patients with cardiac arrhythmia disorders. Her research focuses on understanding the cellular and molecular mechanisms contributing to cardiac arrhythmias and sudden cardiac death in heart failure. Dr. Chiamvimonvat joined the college from University of California (UC), Davis, having served as the Roger Tatarian Endowed Professor of Cardiovascular Medicine and associate chief for Research in the Division of Cardiovascular Medicine. She also served as co-director of the UC Davis Cardiovascular Research Institute and the director for the longstanding T32 Training Program in Basic and Translational Cardiovascular Science, that has trained over 80 trainees through the program.
Her laboratory utilizes multiple approaches to determine the functional significance of the proteins that interact with cardiac Ca2+ and K+ channels. Her team was the first to identify several isoforms of small conductance Ca2+-activated K+ channels (SK channels) that underlie Ca2+-activated K+ current in human atrial myocytes, positioning SK channels as a potential novel drug target for atrial fibrillation. Her team’s research also demonstrated beneficial effects of a novel class of anti-inflammatory agent, soluble epoxide hydrolase inhibitors, in adverse cardiac remodeling in heart failure and arrhythmias.
Dr. Chiamvimonvat's laboratory has been continuously funded over the past two decades by research grants from the National Institutes of Health (NIH), American Heart Association (AHA), and Department of Veterans Affairs. She continues to serve as the Co-Center Director for the UC Davis PRECISE Center funded by AHA Strategically Focused Research Network as well as one of the Principal Investigators for the NIH-funded HeartShare Clinical Center. Her significant contributions have been recognized by numerous awards for research and teaching. In 2023, she received the UC Davis School of Medicine Research Award and the Kaiser Foundation Award for Excellence in Teaching in Basic Sciences.
After receiving her medical degree from the University of Toronto, Dr. Chiamvimonvat completed her residency in internal medicine at the same institution. She finished a fellowship in cardiology at the University of Western Ontario and later completed fellowship training in clinical cardiac electrophysiology at the University of Calgary. She received additional research training at Johns Hopkins University.
