Pun To (Douglas) Yung

Associate Teaching Professor,
Biomedical Engineering Undergraduate Program Director

Biomedical and Chemical Engineering

361 Link Hall



Dr. Yung has long been intrigued by the interfacing of microbes with engineering tools on a micro- and nano-scale. He is unravelling methods to rapidly assess the viability of superbugs and harness energy from extremophiles using a combination of electrochemical, optical techniques and MEMS devices.
