About Me

I am a finance professor at the University of Toronto since 2018. I study the impact of technology on trading, securities exchanges, and asset management, and I try to understand how we can leverage innovation to build better markets. My research was published in leading academic journals such as The Review of Financial Studies, Management Science, and Journal of Financial Markets.
