Dr. Sun is currently Research Associate Professor in the Robert Stempel College of Public Health and Social Work at Florida International University. She got her bachelor degree of Marine Biology and Ph.D. from Qingdao Ocean University, China. She completed postdoctoral training in molecular biology at Seto Marine Biological Laboratory of Kyoto University in Japan and Medical College of Georgia. Over the past 10 years, Dr. Sun has been involved in ongoing technique development to elucidate the mechanisms by which mitochondrial function is disrupted in the pulmonary endothelium in children born with congenital heart defects that result in increased pulmonary blood flow. She has worked closely with Dr. Black to develop the protocols necessary to measure mitochondrial bioenergetics using the Seahorse XF analyzer.
