Hello!

I am a research scientist at AI Lab, CyberAgent, Inc. My research interests lie at the intersection of econometrics, machine learning and economics.

Previously, I was a postdoctoral fellow at the Golub Capital Social Impact Lab led by Susan Athey at the Stanford Graduate School of Business. I received a PhD in Economics from Boston University, where my main advisor was Hiroaki Kaido. My other advisors were Iván Fernández-Val, Ching-to Albert Ma and Jean-Jacques Forneron.
