Lei G. Wang, Ph.D.

  • Assistant Professor of Biomedical Engineering, School of Medicine
  • OHSU Knight Cancer Institute, School of Medicine


Dr. Lei Wang is a faculty member in the Department of Biomedical Engineering at Oregon Health and Science University (OHSU) with a joint appointment in the OHSU Knight Cancer Institute. With expertise in fluorescence chemistry and optical imaging, Dr. Wang leads an innovative research program aimed at the development of novel fluorescence probes and imaging technologies to address clinical challenges. His research interests include near-infrared (NIR) contrast agents for real-time surgical navigation, smart molecular probes for cancer-targeted imaging, and NIR fluorophores for the early detection of neurodegenerative diseases. Dr. Wang's research is supported by funding from the National Institute of Health, Knight Cancer Institute, Brenden Colson Center for Pancreatic Care, and Collins Medical Trust. Motivated by transformative potential of chemistry-driven solutions in precision medicine, Dr. Wang and his team are striving to bridge the gap between clinical needs and basic sciences with innovative imaging technologies.
