Presentations

I've less frequently updated these recently, in part because I give so many talks. Here are some older ones.

2023

  2022

  I switched to Notability for most of my talks and haven't posted these yet. Stay tuned!
  

  2021

  This was the second year of the pandemic, with all talks given remotely. I was involved in organizing sessions at CanaDAM, SIAM Discrete Math, GRASCan, and LGBTQ+Math Day. I gave a few research and EDI talks at conferences and seminars.
