Research
I am interested in the following three areas:
Quantum groups: their algebraic structures and representation theory.
Derived symplectic and Poisson structures: these structures naturally appear in classical field theories (see arXiv:1311.6429), categorified geometric and deformation quantization and so on. See these notes for a non-technical introduction aimed at representation theorists and arXiv:1709.07698 for a more technical introduction. Also see arXiv:1706.02623 for a connection between derived Poisson structures and quantum groups.
Supersymmetric field theories: many conjectures and phenomena predicted by physicists have a rigorous formulation after supersymmetric twisting (see arXiv:1805.10806 for what this means).
I am usually interested in applying ideas from the above areas to neighboring topics: skein theory (arXiv:1901.11450 and arXiv:1908.05233), operads (arXiv:1611.09668), higher categories (arXiv:1804.00879 and arXiv:1904.11312) and integrable systems (arXiv:1302.3540).
