Hi,

I am a fourth-year PhD student under the supervision of Dmitriy Rumynin in the area of Representation Theory. My current research focuses on Knutson's Conjecture on the Representation Ring and the Knutson Index of modules over different objects such as finite groups, algebraic groups, connected and disconnected reductive groups and bialgebras and Hopf algebras.
