## About me

Since July 2016, I have been a Postdoctoral Fellow at the University of British Columbia. Previously, I was a Postdoctoral Fellow of the Swiss National Science Foundation at the University of Chicago. I completed my PhD degree at the École Polytechnique Fédérale de Lausanne (EPFL) under the direction of Kathryn Hess, and my master's and bachelor's degree at ETH Zurich.

I am interested in homotopy theory and its interactions with group actions, commutative algebra and category
theory.

I co-organized the conference Topology Ecuador 2017, August 14 - 18, the summer school EMALCA, Ecuador 2017, August 7 - 11, and the Young Topologists Meeting 2013 and 2011.
