Hello! I'm Naresh Saha

Assistant Professor of Mathematics

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

Previously, I completed my postdoctoral research at the School of Physics, University of Hyderabad, Hyderabad. I conducted 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.

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

Ph.D. Positions Available (Open Positions)

Fully funded Ph.D. positions with institutional fellowships are currently open. Interested and motivated candidates are highly encouraged to contact me directly with a CV and research statement for further details.
