Research Interests
|
|
|
I have been fascinated by many topics in computer vision and machine learning. My research interests in recent years have been more toward interpreting
the visual behaviors of humans and animals from images and videos, biomedical image analysis, and geometric aspect of machine learning. Exemplar efforts
can be found in the follow-up sections of Projects and Selected Publictions.

Brief Bio
|
|
I am an associate professor with the Department of Electrical and Computer Engineering, University of Alberta. I also hold an adjunct position with A*STAR, Singapore, where I have led a group in Machine Learning for Bioimage Analysis at the Bioinformatics Institute. Prior to joining University of Alberta in year 2018, I worked at A*STAR, Singapore, TTI-Chicago, USA, and NICTA, Australia. I received my BSc degree in Computer Science from Jilin University in 1996, M. Eng. degree from Nankai University in 1999, and PhD in Computing Science from the University of Alberta in 2004. My research expertise is mainly on computer vision and machine learning. I am a member of the Institute of Electrical and Electronics Engineers (IEEE), the Association for Computing Machinery (ACM), and the Association for the Advancement of Artificial Intelligence (AAAI). I have supervised or co-supervised a number of research students and postdocs. Many of them have taken scientist or engineer positions at the major tech companies (Google, Nvidia, Bosch, OmniVision, etc.) or hold faculty positions at prestigious universities (e.g. Southeast University of China, China University of Geosciences, University of Adelaide of Australia).

For Potential Graduate Students and Interns
|
|
I
always look for self-motivated students with a strong computer science or computer engineering or mathematics/physics backgrounds who are interested to work on exciting computer vision and machine learning research topics to join my group. Potential PhD and MSc applicants may contact me directly. Students from China may also consider the China Scholarship Council (CSC) award. Short-term research internship is also possible through various funding sources. Please contact me regarding current opportunities.
