Dr Sajal Saha received his PhD from the School of Mathematical Sciences, Universiti Sains Malaysia (USM), Penang, Malaysia. He completed his B.Sc (Honours) in Mathematics and M. Sc in Applied Mathematics from the University of Dhaka, Bangladesh and secured first class in both. In addition to his PhD period, he also taught several mathematics courses to the undergraduate students at School of Mathematical Sciences, Universiti Sains Malaysia (USM), from 2016 to 2018.

He is now working as an Associate Professor in the Department of Mathematics, IUBAT‒International University of Business Agriculture and Technology, Dhaka, Bangladesh. He joined IUBAT in 2012 as a lecturer. He is the Director of the Miyan Research Institute, which is formed by the name of Prof. Dr M AlimullahMiyan, founder Vice-Chancellor of IUBAT, to encourage faculty members and students in research. Dr Saha has a good number of publications in international journals having good Impact Factors. Dr Saha has been reviewing research papers of renowned journals and working as an Associate Editor of the IUBAT Review ‒ A Multidisciplinary Academic Journal. He is a life member of the Bangladesh Mathematical Society.
