I am an Associate Professor in the School of Mathematical and Computational Science, Indian Association for the Cultivation of Science, Kolkata.
My research area is holomorphic dynamics in one and several complex variables. Particularly, I am interested to study problems related to the dynamics of families of holomorphic self-maps of both complex affine and projective spaces, using methods from complex function theory, potential theory and geometric analysis.
