Research Interests

Generally speaking, I am interested in Representation Theory, Quantum Algebra, and Mathematical Physics.

More specifically, my current research interests are:

• Drinfeld presentation of twisted Yangians and affine $\imath$quantum groups
• Twisted Yangians and finite $\mathcal W$-algebras of classical type
• Quantum affine/toroida superalgebras and (affine) super Yangians
• Bethe ansatz and quantum integrable systems
• Gaudin models and Heisenberg XXX, XXZ spin chains
