Dr. Shi-Qiang Wang received his B.S. and Ph.D. degrees from College of Life Sciences, Peking University, China in 1990 and 1998, respectively. In 2003, he completed postdoctoral research in National Institute on Aging, NIH, USA, and retuned to Peking University. In 2005, he was honored as a Cheung Kong Scholar Professor by the Ministry of Education. Dr. Wang’s studies have been focused on the molecular basis of intracellular Ca2+ signaling. He combines state-of-the-art confocal imaging, single-channel patch clamping, single-molecule tracing with molecular cell biology techniques to dissect the molecular mechanisms underlying the generation, amplification and termination of intracellular Ca2+ dynamics, aiming to answer important questions about the function, development and dysfunction of the heart. Many of his work were published in high profile journals, including Nature, PLoS Biology, PNAS and Circulation Research. He gained a number of nationally and internationally-recognized awards and prizes, such as the Chang Hsi-chun Young Investigator Prize by Chinese Association for Physiological Sciences (1997), the Richard J. Bing Young Investigator Award by International Society for Heart Research (2001), the Katz Basic Science Research Prize by American Heart Association (2002),and the National Natural Science Prize of China (2017).

Molecular mechanism of calcium signaling
Ca2+ is a universal intracellular messenger, playing pivotal roles in nearly all biological processes. We combine state-of-the-art molecular imaging, single-channel patch clamping, electron microscopy and molecular cell biology techniques to dissect the molecular mechanisms underlying the generation, amplification and termination of intracellular Ca2+ dynamics, aiming to answer important questions about the function, development and dysfunction of heart cells.
