Other writing
 An informal set of notes from the singularity categories seminar I ran in Lancaster  presented as is with no guarantee of correctness.
 A "poster" I presented at Będlewo.
 A poster I took around a few conferences in summer 2017.
 A quick cheatsheet for dg objects.
 I wrote Chapter 5 of the lecture notes from the TFT Seminar. It's a nicer version of the notes from my talk.
 Differential graded algebras and applications, a report on DGAs written in collaboration with three other PhD students. I wrote Chapter Four and parts of Chapter One.
