"There is no tomorrow!" — Apollo Creed

I'm a graduate student in the Harvard Psychology program advised by Sam Gershman. I also work closely with Kazuki Irie. I'm interested in creating video-game-like experimental tasks and environments to compare how humans and machines learn via reinforcement learning. Through these tasks, I hope to develop models that are both effective in interpreting how humans learn and valuable for optimizing how machines learn.
