About Me

Hi! I'm Samuel Rhys Cox, a computer science PhD student at the National University of Singapore. My primary supervisor is Prof. Wei Tsang Ooi and my co-supervisor is Prof. Brian Y. Lim. I was previously supervised by Joseph Jay Williams before he joined the University of Toronto.

I am interested in human-computer interaction (HCI), human-centered AI, conversational AI, and social computing.

I received my BSc. (Hons) in Mathematics from the University of Portsmouth, and MSc. Computing Science from Imperial College London.
