About

My dream is to create intelligent machines having human-level capabilities, particularly the ability of perceiving and understanding the world through vision. With this long-term motivation, I obtained relevant Bachelor and Master degrees both from Xi'an Jiaotong University, and the PhD degree from National University of Singapore, followed by the participation of multiple interesting AI-relevant research programs mainly in University of Dundee, UK. In the past fifteen years, I witnessed and joined the wave of the shift in AI approaches from the 'old' feature engineering to the 'new' Deep Learning. However, Deep Learning itself cannot achieve the artificial general intelligence (AGI). Creative solutions and novel learning mechanisms need to be developed to solve challenging fundamental problems. Often, these challenging problems are derived from practical applications such as autonomous driving, surveillance, and healthcare. Our research group uses healthcare applications (particularly relevant to medical image analysis) as the engine, driving the exploration and development of novel AI techniques and solutions. If you have a similar AI dream, either planning to study basic AI knowledge and techniques, or looking for a laboratory to continue your AI research, please feel free to drop me an email - we are always looking for highly self-motivated undergraduates, postgraduates, PhD candidates, postdocs, and research professors to join us!
