Dr. Nils Johnson (USA) is a Professor in the Department of Cardiology at McGovern Medical School, UTHealth Houston, with a focus on coronary physiology, particularly linking non-invasive perfusion imaging and intracoronary hemodynamics. He has led major international trials such as CONTRAST and DEFINE-FLOW. His current research includes quantitative FFR pullbacks (PPG registry) and studying aortic valve physiology through the SAVI-AoS initiative. He has published over 140 papers and received numerous awards, including the Rombach Award (2005), Young Clinical Investigator Award from AHA (2009), and Young Author Achievement Award from ACC (2011).

A memory lingering in my mind: Nils was the most handsome doctor I’ve ever known. When I first met him, I thought a movie star, Leonardo DiCaprio, had walked in!
