About Me

Hi! I'm Samuel Rhys Cox, a postdoctoral researcher with the Human-Centered Computing group at Aalborg University working with Prof. Niels van Berkel.

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

I completed my PhD at National University of Singapore, with primary supervisor Prof. Wei Tsang Ooi and co-supervisor is Prof. Brian Y. Lim. I was previously supervised by Joseph Jay Williams before he joined the University of Toronto. I received my BSc. (Hons) in Mathematics from the University of Portsmouth, and MSc. Computing Science from Imperial College London.
