Hi! I am Nina.
I am an executive manager for Compositionality, a
new open-access journal publishing research in the mathematics of
I run a local TDA seminar at UCLA.
Here is my CV.
You can contact me at
math dot ucla dot edu.
- The first volume of Compositionality was published in December
2019! You can find the papers here.
On 7 May 2018 I successfully defended my DPhil thesis at the
University of Oxford.

U. Tillmann), SIAM Journal on Applied Algebraic Geometry, 3(3):439-471 (2019).
A roadmap for the computation of persistent homology (joint with

Upcoming (virtual) travel
Well, I am not really going anywhere, and neither should you!
I will be delivering lectures remotely at the following events:
