Sc. (Hons.), M. Sc. and M. Phil. degrees in Mathematics from the Jahangirnagar University in 1998, 1999 and 2010 respectively. He also earned a one-year postgraduate diploma in Computer Science and Information Technology from CITI (now IIT), JU in 2002. In 2015, he received his Ph. D. degree in Mathematical Sciences from the Meiji Institute for Advanced Study of Mathematical Sciences under Graduate School of Advanced Mathematical Sciences, Meiji University, Tokyo, Japan under a very prestigious scholarship, Global Center of Excellence Scholarship funded by JSPS, Japan. His Ph. D. thesis is mainly concerned with the bifurcation analysis of nonlinear systems through mathematical modeling, analysis and numerical simulation.

Dr. Gani presented his research works in many international conferences (about 25) held in different countries (viz. Bangladesh, Spain, Japan, South Korea, Taiwan, Indonesia, Malaysia and Thailand). He has published several articles in peer-reviewed international scientific journals (Publisher: Elsevier, Easiam, Hindawi, etc.)(https://scholar.google.com/citations?user=5tdORG8AAAAJ&hl=en). He has a research group in nonlinear systems (Applied Computational Mathematics Group) with the BSc/MSc/MPhil/PhD research students and faculty members in his own Department. He is the author of two undergraduate textbooks published in Bangladesh (i. *Business Mathematics *for the BBA Program, and ii. *Complex Variables & Special Functions* for BSc (Hons.) in Mathematics).
