He received his Ph.D. degree in Electrical Engineering at Yale University in USA. His current research interest is the biomedical instrumentation for image-guided cancer surgery, including both open and minimally invasive surgery. Specifically he designed and optimized a medical camera system (for both visible and near-infrared windows imaging) and a spectroscopic device to help surgeons quantitatively distinguish cancerous tissues from normal tissues intraoperatively. Using these devices, he and the surgeons have conducted clinical trials on patients with pancreatic cancer and breast cancer in Emory University Hospital and Emory Saint Joseph's Hospital. His research is the core part of an ongoing TR01 funding ("Contrast-enhanced and Image-guided Surgery") from NIH in USA.
