CV: here
I'm a PhD candidate researching reinforcement learning in the Intelligent Robot Lab at Brown University advised by George Konidaris. My current research interests and work are on agent-state and representation learning in partially observable environments for reinforcement learning. I also think eligibility traces are super neat.
Previously, I was a Computing Science M.Sc. (Thesis) student at the University of Alberta, co-advised by Adam White and Marlos C. Machado in the RLAI lab. Even further in the distant past, I was a First Class Honours and Dean's Honour List student studying Computer Science at McGill University for my B.Sc. I was previously a research intern at both Mila and Microsoft Research.

Hons. B.Sc., 2016 - 2020
Undergraduate research advisor: Joelle Pineau.
First Class Honors, Dean's List.
Experience
National University of Singapore (NUS)
Over the summer of 2020 I was working on a research project advised by Lee Wee Sun on neural-based memory for RL and SLAM.
Mila (Quebec AI Institute)
At Mila, I worked on exploration in a model-based reinforcement learning setting. This was during my final year of my undergraduate degree at McGill. The project was mentored by Vincent François-Lavet and advised by Joelle Pineau. Our paper on this was accepted to NeurIPS 2020 for an oral presentation.
Microsoft Research Montreal
During my time at Microsoft Research, I worked on reinforcement learning and natural language problems. I was advised by Marc-Alexandre Côté on projects including:
-
Adaptive text action spaces: see the above paper.
-
TextWorld: a reinforcement learning framework for agents to learn text-based games.
Articles
-
After my tumultuous time applying for and deciding on a PhD program, I wrote a short guide on how to successfully apply for a CS PhD.
-
I wrote a short piece on the dangers of reshaping in tensor manipulation libraries (PyTorch in this case).
Miscellaneous things about me
-
I have a cooking blog you should check out!
-
In a past life (and technically still), I was a lieutenant in the Singapore Armed Forces and a Combat Engineer by vocation.
-
I spent my formative years in Beijing, and still call it home.
-
I love to read.
-
I love climbing: especially outdoor sport climbing.
