Qiyin Fang is a professor of Engineering Physics at McMaster University and held the Canada Research Chair in Biophotonics from 2005-2016. He is a member of the McMaster School of Biomedical Engineering and associate member of several other programs. Dr. Fang's current research interests include multimodality sensing and imaging technologies for biomedical applications, e.g. optical biopsy, wide-field imaging, endoscopy, microscopy, point-of-care/in-home/wearable sensing systems, and distributed environmental sensing.

Prior to his current position at McMaster, Dr. Fang was a research scientist in the Minimally Invasive Surgical Technology Institute at the Cedars-Sinai Medical Center in Los Angeles.

Dr. Fang obtained both of his graduate degrees from the East Carolina University, where he studied nanosecond laser pulse interaction with soft biological tissue. His undergraduate degree is in physics from Nankai University.

Dr. Fang is an elected fellow of the International Society for Optical Engineering (SPIE).
