Short Biography
-
I am currently serving as a Professor in the Department of Physics at Gopalganj Science and Technology University (GSTU), Gopalganj. My academic journey began with my S.S.C. in 1988 from Naldanga Woomesh Chandra High School and H.S.C. in 1990 from Carmichael College, Rangpur. I earned both my B.Sc. (Hons.) and M.Sc. degrees in Physics from the University of Rajshahi in 1993 and 1994, respectively, securing First Class 1st position in both. Higher studies took me to Japan, where I was awarded my Doctor of Engineering degree from Toyohashi University of Technology in 2003.
I started my teaching career as a Lecturer in the Department of Physics at the University of Rajshahi in 1998, where I was later promoted to Assistant Professor (2004) and Associate Professor (2006). Alongside my teaching, I worked as a Doctoral Research Student and Postdoctoral Researcher at Toyohashi University of Technology, Japan, between 2000 and 2004. In September 2011, I joined GSTU as an Associate Professor and was subsequently promoted to Professor in March 2012.
Throughout my administrative career at GSTU, I have held several key roles, including Chairman of the Department of Physics (2022–Present) and former Chairman of the Department of Electronics and Telecommunication Engineering (2011–2022). I have also served as the Dean of both the Faculty of Science and Faculty of Engineering (3 years each), Registrar (in Charge) for 1.5 years, Proctor for 4 years, Provost of Bijoy Dibos Hall for 4 years, and a member of the Regent Board for 7 years. To date, I have authored 42 peer-reviewed scientific publications and presented my research at 9 international conferences across countries such as the USA, Japan, France, and Singapore. My core research focus encompasses thin-film fabrication, nanoelectronics, semiconductor device characterization, and solar cell applications.
