Biography

Dr. Tsen is an Assistant Professor in the Department of Biomedical Engineering at UT Southwestern Medical Center. He received his B.S. from the Johns Hopkins University and his medical and doctorate degrees from Washington University School of Medicine in St Louis. During Dr. Tsen’s predoctoral years he developed a technology for selective pathogen inactivation via USP laser-induced vibration, a discovery which has been featured widely in news media. Translation of this technology toward applications in clinical disinfection and vaccine production continues to be a goal of Dr. Tsen’s work. During his time as a postdoc and instructor at Washington University School of Medicine, Dr. Tsen played a key role in the development of near-infrared fluorescent imaging agents for detection of solid cancers and treatment response monitoring in arthritis. He is now researching novel photonic technologies to combat infectious diseases, and biocompatible methods to prevent cancer and aging.
