About me

I am currently a post-doctoral fellow at Université libre de Bruxelles with Samuel Fiorini. I was a visiting scholar at the Simons Institute for the Theory of Computing at UC Berkeley, from September 1 to November 1, 2017.  From September 2015 to August 2017, I was a post-doc at University of Waterloo with Chris Godsil . My main area of interest is algebraic graph theory. In particular, my background is in eigenvalues of graphs and digraphs, graph polynomials, association schemes, and linear algebra. I am interested in studying these areas, but also in using tools from these areas in new settings, such as quantum computing and optimization.

I completed my Ph.D. in Mathematics at Simon Fraser University on (2011 – January 26, 2015) under the supervision of Bojan Mohar. The title of my thesis is “Simple eigenvalues of graphs and digraphs”.

I completed my Masters of Mathematics (2009-2010) at University of Waterloo in Combinatorics & Optimization, under the supervision of  Chris Godsil.

My undergraduate degree (2004-2009) is also from University of Waterloo. I have a double major in pure mathematics and combinatorics and optimization.

Here is my curriculum vitae.

I sometimes write expository articles on mathematics that I would like to understand better in the Graphs on Napkins section of this website.

Here’s a video of me  explaining my thesis topic in 3 minutes, as a part of SFU’s 3MT thesis competition in 2013, in which I was a finalist.

I sometimes report on my coffee and math adventures on twitter.
