Dr. Wei GAO

Short Biography

I am currently an Associate Professor (with tenure) in the School of Computing and Information Systems at Singapore Management University. My research interests intersect natural language processing, information retrieval, artificial intelligence and social computing. I received my PhD and MPhil degrees from the Chinese University of Hong Kong and interned at Microsoft Research Asia during my PhD study. Before joining SMU, I was a Senior Lecturer at Victoria University of Wellington in New Zealand (2017-2019), a Scientist at Qatar Computing Research Institute (2011-2017),  and a Research Assistant Professor at the Chinese University of Hong Kong (2010-2011).
