Biosketch

Dr. Boyman's work centers on investigating cardiac calcium signaling and has been the discoverer of important features in cardiac muscle physiology, including the regulation of calcium efflux from cardiac cells and the quantitative aspects of calcium movement in cardiac mitochondria.

He has developed and implemented novel imaging technologies, most of which are designed for investigating calcium signals at high temporal and spatial resolution in cardiac cells. This includes developing tools to carry out quantitative measurements of mitochondrial Ca2+ signals in real-time using genetically targeted probes, new oxygen micro sensors to investigate the effect of ischemia on mitochondrial Ca2+, and new biochemical fluorescent applications to quantify mitochondrial Ca2+ fluxes through specific ion channels and exchangers. In addition to the effort to develop new tools he has extensively collaborated with many other investigators to implement these new tools in their ongoing investigation.
