SOLNESS: Castles in the air?
HILDA: Yes! Castles in the air — they're so easy to hide away in. And easy to build too.
(Looking contemptuously at him.) Especially for builders who have a dizzy conscience.

I am a fifth year PhD student at Stony Brook University, working under the supervision of Simon Donaldson. Starting from July 2019, I will be a Junior Fellow of the Simons Society of Fellows and a Postdoctoral Research Scientist at Columbia University. I will also hold a Junior Research Fellowship at Trinity College, University of Cambridge.
Here is a picture of me; and another one here.

My PhD dissertation at Stony Brook University. It incorporates some of the material from my first five papers, three of which were written in collaboration with Thomas Walpuski. The introduction is a short survey of generalized Seiberg-Witten equations, Fueter sections, and their relation to gauge theory in higher dimensions.
