I am currently a Postdoctoral Fellow at Max Planck Institute for Mathematics , Bonn.

I was a Postdoctoral Fellow at Institut Fourier (Grenoble) supervised by Michel Brion.

I completed my Ph.D. in 2016 under the supervision of S.Senthamarai Kannan at Chennai Mathematical Insitute, Chennai, India.

I was a visiting Research Scholar with Henning Andersen at QGM, University of Aarhus, Denmark, in 2015.

My thesis title "Torus quotients and Automorphism group of a Bott-Samelson variety".

M. Sc. in Mathematics, University of Hyderabad, Hyderabad, India.

Research interests

    My research interests lie in Algebraic Geometry, Algebraic Groups and Representation Theory. Mainly Flag varieties, toric varieties and spherical varieties.
