BACKGROUND

A Bangladeshi citizen, currently working as a Professor in Electronics and Communication Engineering Discipline, Khulna University, Bangladesh. I have conducted several theoretical/sessional courses for both the Undergraduate and Graduate students in several government/private Universities/ Institutes. Graduate courses include Laser Processing of Materials, Fiber-optic Communication, and Electronics of Solids. Undergraduate courses include Electrical Circuits, Electronic Devices and Circuits, Digital Electronics, Numerical Methods, Industrial Electronics, Digital Communication, Optoelectronic Devices & Optical Communication, Management Information System, and Information Technology. I have advanced research experience in laser processing of transparent, non-transparent, and magnetic materials. In addition, I have research experience in designing and analysis of various photonic devices (Intense Light Beam, LEDs, OLEDs, organic solar cells, and PCFs), passive optical networks (PONs), road traffic information system, and agricultural drones. The current research is focused on photonic devices and mechatronics (drones/robots).
