About Me:

I am an Associate Professor in the Department of Mathematics at the National Institute of Engineering (NIE), Mysuru. Before joining NIE, I was an Associate Professor at GSSSIETW, Mysuru. 

I was Post Doctoral Fellow at IISc, Bengaluru. During my stay at IISc, I worked on the distribution of quadratic residues modulo prime p with Prof. Sunil Chandran and Dr. Siddarth Barman. 

I obtained my PhD at NITK Surathkal under the supervision of Prof. S M Hegde. My PhD thesis mainly deals with the proof of three conjectures on graceful digraphs. I was honoured to recieve the best paper award during the National Meet of Research Scholars in Mathematical Sciences (NMRSMS)-2010 at IIT Madras. Also, I had the previlage of being awarded the NBHM and the Dr. D S Kothari Post Doctoral Fellowships.

My current research focuses on finding bound on the number of k-term arithmetic progressions of quadratic residues and nonresidues modulo prime p
