Diagnostic ultrasound: system design, advanced imaging paradigms, application development.
Therapeutic ultrasound: biophysics, cellular bioeffects, treatment strategies.
Alfred C. H. Yu is currently 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. His graduate work was supported through the Canada Graduate Scholarship program sponsored by the Natural Sciences and Engineering Research Council of Canada.
Alfred’s research interests are broadly centered around the field of biomedical ultrasound. Over the course of his graduate studies, he has been involved in the theoretical modeling of ultrasound signals and the design of novel signal processing strategies for medical ultrasound systems. He has also worked as a graduate research intern at Philips Research, Briarcliff Manor, NY, USA in 2005 to participate in the development of novel ultrasound-based medical devices. His group’s current research efforts are driven by two aims: 1) developing new and better ways of using ultrasound as a diagnostic and therapeutic tool in biomedicine, and 2) investigating the science behind various ultrasound-induced wave-matter interactions.
Alfred has been an active contributor to curriculum innovations since joining the university. He has been leading teaching development projects and designing new courses for the Medical Engineering Program and the Common Core Curriculum, and he is engaged in the scholarship of teaching and learning from a practitioner’s perspective. 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 a wide range of courses that span from freshman to postgraduate level.
Alfred is an IEEE member, and is now serving as the Vice-Chair of the IEEE-EMBS Hong Kong Chapter to help promote biomedical engineering as one of the high-potential research areas in Hong Kong. He is also spearheading knowledge-exchange initiatives that aim to develop Hong Kong students’ interests in technological innovations and third-world development.
In his leisure time, Alfred enjoys playing sports, particularly outdoor ones. He is a crappy golfer with a +30 handicap, though he once did manage a hole-in-one at the Rolling Hills Golf Club in Toronto. He is also a football fanatic: one who always likes to support underdogs in matchups.
