Profile Summary 

Dr. Sahni has 15 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.
