Short presentation
Hi there! I am a postdoc doing research in the areas of string topology, noncommutative geometry and symplectic topology. I also like thinking about TQFTs, categorical invariants in mirror symmetry, and operadic structures in quantum theory.
I previously held a postdoc position at IHES, working under the supervision of M. Kontsevich, and got my PhD in Physics from UC Berkeley in 2019, supervised by M. Aganagic and V. Shende.
Keywords
- calabi-yau structures
- string topology
- noncommutative geometry
- mirror symmetry
- higher categories
Biography
- 2023-current: Postdoc in mathematics at Uppsala University
- 2020-2023: Postdoc in mathematics at IHES
- 2013-2019: PhD in Physics at UC Berkeley, under the supervision of Mina Aganagic (Physics) and Vivek Shende (Mathematics)
