Gave an invited talk titled "Invariance in Hardy Spaces" at the 100th Indian Science Congress on Jan 05, 2013 at Calcutta University, Kolkata, India.

Niteesh has 11 years of teaching experience in pure and applied mathematics at undergraduate and graduate level. He works in Functional Analysis and Dynamical systems. The highlight of his research has been to settle an open problem in Hardy-Hilbert spaces. Presently, he is involved in solving problems related to invariant subspaces of Bergman spaces, BMOA, and vector valued Hardy spaces.
