Pun To (Douglas) Yung

Associate Teaching Professor, Bioengineering Undergraduate Program Director

Biomedical & Chemical Engineering

MEMS and microfluidics, biosensor development, microbial engineering, astrobiology

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.
