# Ronald P. Karlsberg

Ronald P. Karlsberg is an American academic and cardiologist. He is a clinical professor of medicine at the Cedars-Sinai Medical Center and the David Geffen School of Medicine at UCLA, specializing in clinical, preventive, and interventional cardiology.

## Early life and education

Karlsberg received his medical degree from the University of California, San Francisco, completed his residency at the University of Colorado Medical Center, and pursued a fellowship in cardiology at Washington University School of Medicine in St. Louis, Missouri.
Karlsberg is board certified in internal medicine, cardiovascular disease, and cardiovascular computed tomography. He is a Master of the Society for Cardiovascular Computed Tomography.

## Academic career

Karlsberg began his career as an academic at the University of California, Irvine, where he served as the director of cardiac wards and research at the Long Beach VA. He later joined the faculty at UCLA and has made contributions in consultative cardiology and clinical research, with a particular focus on coronary artery disease.
Recognized for his work in informatics, Karlsberg created a notable electronic health record system, one of the earliest on the internet. He conducts a masters course in coronary CT angiography and is an expert in advance office-based cardiac imaging.
Karlsberg has been instrumental in leading innovations in areas of cardiovascular research including personal point of care medical devices. He has been an active member of the informatics committee of the American College of Cardiology (ACC) and has contributed to the development of national electronic record standards for cardiac outcomes. He has been on the Board of the Society for Cardiac Computed Tomography (SCCT) establishing standards in that field. The ACC appointed him to the Intersociety Commission for the Accreditation of Computed Tomographic Laboratories (ICACTL).
Karlsberg also co-founded and now serves as chairman of the Cardiovascular Research Foundation of Southern California.

## Research

His research interests focuses on translational research in the areas of clinical cardiology, Coronary CT angiography, medical imaging, health informatics, artificial intelligence, point of care medical monitoring, and multicenter medical research trials.
