## Teaching

I taught the following courses:
- 2021-2022 - Lecturing and tutoring part of the Facets of Mathematics course at the University of Edinburgh<\li>
- 2017-2020 - Supervisor for Part II Topics in Analysis and Part II Numerical Analysis at the University of Cambridge
- 2014-2016 - Tutor for Analysis I and II at the University of Rostock

## Academic Activities

In 2020 I co-organised the Mathematics of Data Science conference, and wrote a short lessons learned paragraph about it.

In the academic year 2018/2019 I was one of two directors of the Part III seminar series at the University of Cambridge.

I enjoy reviewing papers within my area of expertise.
