Profile

Dr. Y T Yu received the B.Sc. degree in Mathematics with First Class Honours, and the Certificate in Education from The University of Hong Kong. Later, he received the Graduate Diploma and obtained First Class Honours and First in Class in a M.Sc.(Prelim) Course before receiving the Ph.D. degree from The University of Melbourne, Australia.

Prior to joining the Department of Computer Science of City University of Hong Kong, Dr. Yu has taught computer courses in The University of Melbourne, The University of Hong Kong, and The Hong Kong Institute of Education. He has substantial experience in secondary computer and mathematics education in Hong Kong. He has led the implementation of strategic computerisation project of a secondary school, including in-house development of various essential school administration software systems. He was also the author of two textbooks for Computer Studies.

Dr Yu has been actively involved in research work. His publications have appeared in many scholarly journals, including the most prestigious journals in the field of software engineering, such as ACM Transactions on Software Engineering and Methodology and IEEE Transactions on Software Engineering. To date, his research projects have been funded by more than 10 strategic and competitive earmarked research grants, and development projects supported by teaching development grants. In addition, he has also participated in a research and development project, which is supported by a fund from the Innovation and Technology Commission.
