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 Fall 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 (on leave in the academic year 2019/2020).

Here is a picture of me; and another one here.
