Biography

I am an assistant professor at the Department of Computer Science, the University of Hong Kong, and a cofounder of Reka. I earned my Ph.D. in computer science from the University of Oxford. In the past, I obtained a Master of Science degree from the National University of Singapore, and a Bachelor of Engineering degree from Shandong University. My research interests include natural language processing and machine learning. My research is centered on enabling computers to comprehend human language. I also spent some time at Google DeepMind, Facebook AI Research, and Microsoft Research before and during my PhD study.

I have multiple fully-funded PhD, MPhil, postdoc, RA, and intern positions available at the University of Hong Kong. Email me for more information.

Reka is hiring for platform and machine learning. Email us for more information. We are an AGI company committed to the development of large foundation models.
