Biography
I am a Postdoctoral Research Scholar at the University of Chicago’s Data Science Institute. In July 2023, I am joining the Department of Statistics and Actuarial Science at the University of Waterloo, and will be a faculty affiliate at the Vector Institute. I completed my PhD in Statistical Sciences as a Vanier Scholar at the University of Toronto. During my PhD I was also affiliated with the Vector Institute. My research interests focus around computational statistics and statistical learning theory.
