My research area is the theory of automorphic representations.
I mainly work on the local Langlands correspondence, Arthur’s multiplicity formula and liftings of automorphic representations for classical groups.
The Langlands conjecture, which is a generalization of the class field theory,
predicts a natural but mysterious correspondence between automorphic representations and Galois representations.
The local Langlands correspondence, which is a local analogue,
associates irreducible representations of reductive p-adic or Lie groups and their so-called L-parameters.
For classical groups, it was established by Arthur in 2013.
I study several notion (e.g., theta liftings, Jacquet modules) in representation theory in terms of L-parameters.
