Short CV

Since January 2021, I am an Assistant Professor at University of Massachusetts Amherst. Before, I was an MSI Fellow at the Australian National University (2019-2021), a postdoctoral member of the MSRI program on Higher categories and categorification (Spring 2020), and a Postdoctoral Fellow of the Swiss NSF at Johns Hopkins (2017-2019). I got my PhD in 2017 at EPF Lausanne Switzerland, under the supervision of Kathryn Hess. My research is supported by the NSF grant 2203915.


Research Interests

  • Higher category theory
  • Homotopy theory
  • Algebraic topology

  • (∞,n)-categories with Dimitri Ara, Andrea Gagna, Lyne Moser, Viktoriya Ozornova, Nima Rasekh, and Dominic Verity

    These papers develop certain aspects of the theory of (∞,n)-categories or new model categories for (∞,n)-categories for general n. Most of my work focuses on the model of n-complicial sets.
