Hi! I am Nina.
mathematics and other stuff.
I am an executive editor for

On 7 May 2018 I successfully defended my DPhil thesis at the
University of Oxford.
The Applied Category Theory School is an initiative to bring early
career researchers into the applied category theory community. The
school consists of an online seminar and a research week. It took
place for the first time in 2018, the research week being hosted at the
Lorentz Center in Leiden. The 2019 edition will be hosted in
Blog posts written by the participants of the ACT 2018 School can be found on the . For more information, see

University of Oxford:
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
