Dr. Chang received her Ph.D. in Molecular and Cellular Pharmacology at University of Miami School of Medicine in Miami, Florida. She obtained her postdoctoral training in the Department of Physiology at UTSW, and moved up the ranks to Assistant Professor in Internal Medicine, Division of Nephrology and Center for Mineral Metabolism. Dr. Chang has had a longstanding interest in utilizing multi-faceted approaches to identify and characterize physiological and pathophysiological signaling mechanisms that affect muscle contractility. She is currently focused on understanding 1) signaling mechanisms that maintain constitutive cardiac myosin phosphorylation at levels necessary for normal cardiac performance, and 2) how aberrant extracellular signals are transmitted to affect basal myosin phosphorylation levels in vivo in patients with chronic kidney disease.
