About Me

I am a Senior Researcher in the Reinforcement Learning Group at Microsoft Research in Redmond, WA. I previously obtained a PhD in Computer Science from the University of Texas at Austin advised by Professor Peter Stone.

I work at the intersection of deep learning and reinforcement learning to develop autonomous agents capable of adapting and learning in complex environments.

Open Source Software

I’ve built or contributed significantly to the following open-source projects:

Jericho is a lightweight python-based interface connecting learning agents with interactive fiction games. It serves as a testbed for benchmarking progress of language-based agents on man-made text games. BlogPost
Half Field Offense (HFO) is a multiagent subtask in RoboCup simulated soccer, modeling a situation in which the offense of one team has to get past the defense of the opposition in order to shoot goals.
Arcade Learning Environment (ALE) Is a well known platform for training learning agents to play Atari games. I developed the first external interface to ALE which allowed the environment to be used as a library.
