I am a PhD candidate in Maths at University of Cambridge. My supervisor is Jacob Rasmussen. I will be on the job market this fall. You can see my complete CV here.

I am interested in low-dimensional topology, especially about gauge theory (Instanton, monopole, Heegaard Floer homology) and knot polynomials (Khovanov homology, $\mathfrak{sl}_n$ homology, HOMFLY-PT polynomial). I also have interests in symplectic geometry and mathematical physics.
