About me

I am an MSI Fellow at the Australian National University. I will also be a postdoctoral member of the MSRI program on Higher categories and categorification during January-May 2020.

Before, I was a Postdoctoral Fellow of the Swiss NSF at Johns Hopkins, working with Emily Riehl. I got my PhD in 2017 at EPF Lausanne (Switzerland), under the supervision of Kathryn Hess.

Research

I do algebraic topology, homotopy theory and higher category theory.

My current research, joint in different combinations with Julie Bergner, Daniel Fuentes-Keuthan, Magdalena Kedziorek, and Viktoriya Ozornova, focuses on studying the homotopy theory of higher categories (e.g., comparing models of (∞,n)-categories and developing certain aspects of the theory of (∞,1)-categories).

I also have a series of papers (joint with Julie Bergner, Angélica Osorno, Viktoriya Ozornova and Claudia Scheimbauer) on the topic of 2-Segal spaces and their relation with the Waldhausen construction.

My PhD thesis focused on the study of homotopy invariants of principal bundles and geometric interpretations of characteristic classes.
