Wilson (Weixin) Cai

I obtained my Ph.D. in Biostatistics at UC Berkeley. I am fortunate to be advised by Professors Mark van der Laan and Alan Hubbard. My research interests lie in Machine Learning and Causal Inference.

I graduated from the Univeristy of Hong Kong with a B.Sc. (Honors) in Statistics and double major in Finance. I was awarded the Saw Gold Medal in Statistics (magna cum laude) and Undergraduate Research Fellowship during my graduation at HKU.

Prior to joining UC Berkeley, I was a visiting researcher at UC Davis working with Prabir Burman. I also worked under the able guidance of Prof. Alexander Aue and Prof. Debashis Paul.
