Anibal Maximiliano Medina-Mardones

Hi there! I am Anibal M. Medina-Mardones, a mathematician working on theoretical and applied topology. I am originally from Patagonia, Chile and the picture above shows Cerro Castillo near my hometown, Coyhaique.

I recently moved to Canada to work for Western. Previously, after studying with Dennis Sullivan, I worked for Stanford, Notre Dame, EPFL, MPIM, and Paris Nord.
