BIOGRAPHY:

Alfred C.H. Yu is a Research Assistant Professor in the Department of Electrical and Electronic Engineering and a core member of the Medical Engineering Program. He was born in Hong Kong in 1980 and had moved to Canada with his parents when he was 10 years old. He received his B.Sc.(Distinction) degree in Electrical Engineering from the University of Calgary, AB, Canada, in 2002. He then completed his M.A.Sc. and Ph.D. degrees in Electrical Engineering (Biomedical Stream) from the University of Toronto, ON, Canada, in 2003 and 2006 respectively. In between, he completed a corporate internship at Philips Research, Briarcliff Manor, NY, USA in 2005.

Alfred’s research interests are centered around the engineering science of biomedical ultrasound. He is always keen on investigating two high-level research questions: 1) how to generate nice pictures using ultrasound; 2) how does ultrasound interact with living cells to bring about therapeutic effects. His lab is now actively pursuing various inquiry-driven research studies in diagnostic and therapeutic ultrasound. Their research has received quite a few accolades in recent years, including a Best Student Paper Award (3rd Place) at the 2011 ISTU Symposium and a Young Scientist Award at the 2012 USE Conference.

Alfred is an IEEE Senior Member, and he was the Chairperson of the IEEE-EMBS Hong Kong Chapter from 2010-2012 to help promote biomedical engineering as one of the high-potential research areas in Hong Kong. He is also an active contributor to curriculum innovations. In 2009, he received the IEEE Real World Engineering Project Award: an international recognition for designing high-quality, tested, society-focused project courses for junior engineering students worldwide. He currently teaches courses in both the Medical Engineering Program and the Common Core Curriculum.
