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.
