About

I am a PhD candidate in Computer Science at the University of Toronto, where I am advised by Dr. Tovi Grossman and Dr. Anthony Tang. My research interests lie in how we can facilitate interactions between humans and robots. My research has been supported by the NSERC CGS-D Fellowship and the Google PhD Fellowship. My work is regularly published at top human-computer interaction venues including CHI, HRI, and UIST, where I have received 2 best paper awards and 1 honorable mention award. I have also spent considerable time in industry research labs including at Google DeepMind, Meta Reality Labs, Autodesk Research, and Honda Research Institute.

I am on the job market in the 2024-2025 cycle. I am seeking tenure-track positions in academia or industry research roles. Please reach out if you are interested!
