My research explores the representation theory of connected reductive groups over non-archimedean local fields — a field rich with connections to number theory, harmonic analysis, and algebraic geometry. I'm particularly focused on branching problems for irreducible smooth representations, shedding light on how representations behave when restricted to subgroups.

Branching rules for all irreducible smooth representations of unramified U(1,1)
Supervisor: Dr Monica Nevins
In my doctoral thesis, I prove that for the rank-one quasi-split unitary group G, the restriction of all irreducible smooth representations of G to a maximal compact subgroup K is multiplicity-free, characterised by distinct depth and degree, up to scaling by a quasi-character of G. The decomposition is given in terms of explicit irreducible representations of K that I construct. Moreover, I show that in a neighbourhood of identity, the decomposition is governed by representations constructed using nilpotent elements in the Lie algebra of G, thereby proving a new case of a recent conjecture.
Currently preparing two preprints and exploring the ramified case.
Broader Research Goals:
Develop branching rules for higher rank unitary groups and explore the relationship with LLC.
Investigate the unicity of types for supercuspidal representations.
Study symmetry-breaking operators in the p-adic setting.

I classified irreducible representations of GL(2)over finite fields. This work led to a collaborative project analysing Alexandru Tupan’s proof of the Gelfand-Kazhdan theorem, adapted to the metaplectic cover of GL(2).
