About Me

Hello! I am an assistant professor of mathematics, teaching stream, at the University of Toronto Mississauga.

I am involved in a wide range of mathematics education projects with themes around active learning and assessment design: more recently, flipping a discrete mathematics course, and validating a concept inventory for proof-based courses. I also published my discrete math course notes as an OER text using PreTeXt. Other interests include algorithms for linear optimization with connections to the geometry of polyhedra.

Classes start this week and why do I constantly feel like I am behind on course prep? So. Many. Things. To. Do. :D The FSP bootcamp I joined is helping for sure in terms of time management but I find that I’m having to tweak some of the methods so that they can work for a teaching stream workflow where 80-90% of the work is focused on teaching and the rest on service (as opposed to research stream where the split is 40/40/20 research/teaching/service).


After all of the webinars and workshops and conferences I attended over the summer it is finally time to sit down, write a syllabus, and make pedagogical decisions about my courses.

One Month To Go

Ok, cool. I’ve created ten videos so far for MAT202 and MAT136 combined. Nowhere where I wanted to be at this point but it’ll do. I like my current setup now of using Drawboard for PDF annotation and OBS for screen-capture.
