Hello! 

I'm Naresh Saha, currently working as an Assistant Professor at the Department of Mathematics, School of Engineering, Dayananda Sagar University, Karnataka, India. 

Previously, I have done my postdoc at the School of Physics, University of Hyderabad, Hyderabad. I have done my Ph.D. research work at the Physics and Applied Mathematics Unit, Indian Statistical Institute in Kolkata, India. I pursued my Master of Science (M.Sc.) in Mathematics at West Bengal State University, Kolkata, and my Bachelor's degree in Mathematics from Barasat Government College, Kolkata.

My research focuses on the dynamics of Soliton and Solitary Waves in nonlinear partial differential equations, which I find incredibly fascinating. Also, I am interested in working in pattern formation in reaction-diffusion equations. Currently, I am working on problems in graph theory as well.
