About

I did my B.Sc and M.Sc from Hindu College, Unversity of Delhi, Delhi during 2004-2009. After the completion of my M.Phil, I joined for PhD at the Department of Mathematics, University of Delhi, Delhi in May 2011 and submitted my thesis in Nov 2013 with the viva-voce being held in Nov 2014. I started my teaching profession as an Assistant Professor (on ad-hoc basis) in the Department of Mathematics, University of Delhi in Jan 2014 and joined as an Assistant Professor (on permanent basis) in Department of Mathematics, Ramanujan College, University of Delhi in Mar 2014. Recently, I have joined the Department of Mathematics, University of Delhi (on permanent basis) in Oct 2022.

My research interest is in geometric function theory, an active area of complex analysis.
