Hi! I'm a second-year PhD student at University of Toronto co-advised by David Lindell and Kyros Kutulakos. Previously, I did my undergrad and master's at MIT, supervised by Frédo Durand and Wojciech Matusik. I'm interested in computer graphics, machine learning, algorithms, and more.

Math Olympiad Handouts

I've written a number of handouts for national math olympiad training camps. Recommended handouts are indicated with a 🌟.

Algebra Combinatorics
  • Graphs, Graphs, Graphs - 2025 Canada Winter Training
    Graph theory, from handshaking to Caro-Wei. Hints to problems are included in the back.
Geometry
  • Projective Geometry - 2021 Canada Summer Training
    Basics on projective geometry.
  • A Few (Geometry) Problems - 2021 Canada Summer Training
    A few interesting problems with a different flavour from olympiad geometry.
  • Incircles - 2021 Canada Summer Training
    Some simple facts about incircles and some not-so-simple problems about incircles.
  • Complete Quadrilaterals and the Miquel Point - 2021 Canada Summer Training
    A closer look at a general configuration. Please let me know if you solve C7.
  • Ratio Chasing - 2021 Canada Winter Training
    Powerful applications of Ceva's, Menelaus's, and Law of Sines. Still counts as synthetic.
  • Weird Geometry - 3020 Canada Summer Training
    A grim prediction of olympiad geometry 1000 years in the future.
  • Tangent Circles - 2020 Canada Summer Training
    TL;DR either use inversion or look for a Miquel point. Sometimes both.
  • A Few Configurations - 2020 Canada Winter Training
    Around the orthocenter, incenters and excenters, and isogonal conjugates.
Number Theory

Projects

Some CS projects from undergrad.
  • Spheres
    What happens when you add spheres?
  • Balloons
    Make balloons. Fly away.
  • Stained Glass Radiance Fields
    Differentiably rendering triangle soups to learn radiance fields for my 6.869 final project.
  • Surface Reconstruction
    Solving the Poisson Surface Reconstruction problem with an FMM-like approach for my 6.335 final project.
  • Pencil Sketching
    6.838 final project done with Eric Zhang. Real-time pencil rendering with triangle meshes and with signed distance fields.

Competitive Programming

I've written over fifty problems for competitive programming contests. Here are some of my favourites:
