I am now a Postdoctoral Fellow at MIT. I received my Ph. D. from University of Geneva under the supervision of Prof. Anton Alekseev in 2016. Here is my CV.

Teaching:

18.708. Topics in Algebra, Instructor (MIT 2017/18).

18.02. Multivariable Calculus, Recitation Instructor (MIT 2017/18).

MIT Primes Mentor 2017/19.

Research:

My research interests include Mathematical Physics, Symplectic and Poisson geometry, Representation Theory. My current research is partially sponsored by Swiss National Science Foundation Grant P2GEP2_165118, P300P2_174284 and P3P3P2_174285.
