I joined CUSAT Maths department in 2015. Before that, I worked at PSMO College (2014-15), University of Calicut (2012-13). I was a postdoctoral fellow at Kerala School of Mathematics (2013-14). I completed my masters and PhD from CUSAT Maths Department.

My research interest is broadly on Functional Analysis. I work on the spectral approximation problems on Hilbert spaces, with applications to concrete examples.
