- In Spring 2015, I helped Alan Weinstein with the organization of the Freshman Seminar (MATH 24) on "Geometry, Relativity, and the Fourth Dimension" at UC Berkeley.
I was co-organizer of the Zurich Graduate Colloquium, intended to be a "What is...? "-type of Colloquium, given by graduate students and postdocs, at UZH and ETH.
Also in Zurich, during the Fall Semester 2013, I organized the seminar
The moduli space of flat connections, for advanced undergraduate students, Master and PhD students. This is the program of the course. Notes of the special talks given by Victoria Hoskins for the seminar can be found here.
