Hi! I am Nina.
I am an executive manager for
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.
Preprints and recent publications
persistent homology (joint with H. Schenck, H. Harrington,
U. Tillmann), SIAM Journal on Applied Algebraic Geometry, 3(3):439-471 (2019).
A roadmap for the computation of persistent homology (joint with
M. Porter, U. Tillmann, P. Grindrod, H. Harrington), EPJ Data
Science 2017 6:17 (2017). A combined pdf of the paper and the supplementary material is here.
All processed data sets used in the benchmarking, as well as scripts used to measure memory, all scripts written for the tutorial, and an updated list of libraries for PH can be found
and phylogenetic trees (joint with J. Baez), Theory and
Applications of Categories, 33(40):1397-1453 (2017).

Upcoming (virtual) travel
Well, I am not really going anywhere, and neither should you!
I will be delivering lectures remotely at the following events:
University of Oxford:
Spring 2019: Math 168 Introdution to Networks
In Hilary and Trinity Term (January–June) 2017 I was tutoring Topology at New College and St Hugh's College.
In Hilary (January–March) 2017 I was the class tutor for Computational Algebraic Topology. I also gave a tutorial on Category Theory for the Stanford in Oxford programme.
In Hilary and Trinity Term (January–June) 2016 I was the tutor for Topology at New College.
About TeX (from here):
In general, TeX usage is pretty much like being a guest at somebody
There are zillions of stuff that you have absolutely no idea what they
So don't fiddle too much. Just enjoy your stay and get out as soon as
