He is board certified in internal medicine, cardiovascular medicine, advanced heart failure and transplant cardiology, and echocardiography.

    His research interests include outcomes research for heart failure, antibody desensitization, cardiogenic shock, and heart transplantation, and he is a principal investigator for several national clinical trials studying novel heart failure and heart transplant therapeutics including post-acute myocardial infarction related cardiomyopathies, hypertrophic cardiomyopathy, non-invasive heart transplant rejection surveillance, and physics-based artificial intelligence solutions for heart failure. Dr. Vaidya is also the recipient of a nearly $5M grant as lead principal investigator of the prestigious “Judge John A. Houston Artificial Intelligence Technology for Heart Monitoring Project”. He has authored multiple peer-reviewed journal articles, book chapters, and abstracts and leads his own research lab here at the University of Southern California.
