Dr. Xiangcheng Sun joined Department of Chemical Engineering at Rochester Institute of Technology as an Assistant Professor in the fall of 2021. Prior to RIT, Dr. Sun obtained his Ph.D. degree in Chemical Engineering at the University of Connecticut, and conducted postdoctoral research at Cornell University and UC Santa Barbara. His current research interests include design, preparation and application of novel fluorescent materials. He uses fluorescent materials for portable sensors in the environmental and biomedical areas. In addition, he investigates catalytic reaction mechanisms and develops efficient catalysts with the designed fluorescent organic dyes, single-molecule catalysis and super-resolution imaging techniques.
