M.Sc. in Applied Mathematics (Khulna University) 

B.Sc. (Honors) in Mathematics (Khulna University)

My current research interests are centered on applied mathematics. Currently, I am working on combinatorial optimization, numerical methods, and mathematical modeling. In combinatorial optimization, my work focuses on investigating how multiple heuristics and metaheuristic algorithms can be effective tools for solving Vehicle Routing Problems. My work in mathematical modeling centers on describing physical phenomena using differential equations and analyzing how the system evolves over time.

Some of my works are listed below.
