Hello! I completed my Ph.D. at the Department of Mathematics of the University of Toronto, under the supervision of Joel Kamnitzer, in August 2014. My research focused on the geometry of hypertoric varieties. You can check my LinkedIn profile to see what I do these days.
My Ph.D. thesis: Hypertoric varieties and wall-crossing. The slides from my thesis defense are here.
Here's a little web app I made to visualize the voting records of Toronto City Council members during the 2010-2014 term.
Some of my expository writing from my days as a mathematician:
Computing the order of a solvable black-box group in quantum polynomial time, with applications
Shift equivalence and strong shift equivalence of subshifts of finite type
Non-Kähler Hamiltonian torus actions
Complex line bundles and gerbes (my M.Sc. research project)
The flow category of a Morse function
Equidistribution and Weyl's criterion
