Stephen Chang, MD, PhD
Clinical Scholar, Medicine - Cardiovascular Medicine
Postdoctoral Research Fellow, Biochemistry
BioPrior to a career in medicine, Dr. Chang was an English major and subsequent novelist at night. During the days, he taught literature part-time at Rutgers University, and for extra money, worked in a laboratory in NYC washing test tubes. Inspired by his laboratory mentor, he began volunteering at the hospital next door, and developed a love for interacting with patients. Through this experience, he saw how caring for others could form deep bonds between people - even strangers - and connect us in a way that brings grandeur to ordinary life.
In addition to seeing patients, Dr. Chang is a physician-scientist devoted to advancing the field of cardiovascular medicine. His research has been focused on identifying a new genetic organism that better models human heart disease than the mouse. For this purpose, he has been studying the mouse lemur, the smallest non-human primate, performing cardiovascular phenotyping (vital signs, ECG, echocardiogram) on lemurs both in-bred (in France) and in the wild (in Madagascar) to try to identify mutant cardiac traits that may be heritable - and in the process, characterize the first high-throughput primate model of human cardiac disease.

Clinical Associate Professor, Medicine - Cardiovascular Medicine
Current Research and Scholarly InterestsMy research endeavors are focused on populations with connective tissue disorders that manifest as cardiovascular abnormalities, such as Williams, Marfan, and Loeys-Dietz syndromes. Additionally, as a member of the California Center of BD-Steps II, I study birth defects associated with congenital heart disease.
John P. Cooke, MD, PhD
Professor of Medicine (Cardiovascular Medicine), Emeritus
Current Research and Scholarly InterestsOur translational research program in vascular regeneration is focused on generating and characterizing vascular cells from human induced pluripotential stem cells. We are also studying the therapeutic application of these cells in murine models of peripheral arterial disease. In these studies we leverage our longstanding interest in endothelial signaling, eg by nitric oxide synthase (NOS) as well as by nicotinic cholinergic receptors (nAChR).
