My last name rhymes with "phone" :)

Hi, I'm Sally! I'm a final year PhD student in the theory group in the Allen School at the University of Washington. I am advised by Professors Yin Tat Lee and Thomas Rothvoss. My research interests are broadly in algorithms and combinatorics.

I received my bachelor's degree from the University of Waterloo in Canada, where I was a part of the wonderful Combinatorics and Optimization department.

I will be graduating in summer 2024 and am looking for a position after. I'd love to hear about any opportunities and interesting problems to work on!
