About Me
About Me
I am a Research Team Lead at the Electronic Devices Branch (RYDD) of Air Force Research Laboratory (AFRL), Sensors Directorate. We are located at the Wright-Patterson Air Force Base in Dayton, Ohio. Our multi-disciplinary team works on the development of electronic device technologies for high power, high frequency, and high temperature applications. We use wide-bandgap (WBG) GaN and ultra-wide bandgap (UWBG) beta-Ga2O3 as semiconducting materials and focus on device performance improvement by utilizing materials innovation, microfabrication, defect engineering, and novel device design.
Before joining the device group at AFRL/RYDD, I worked as a Research Engineer/Technical Advisor of KBR, Inc. (2019-2020) with AFRL/RYDT and as Research Scientist of UES, Inc. (2012-2014, 2016-2019) and National Research Council (NRC) Postdoctoral Fellow (2014-2016) with the Flexible Electronics Group of Materials and Manufacturing Directorate (AFRL/RXAS). During this period, I worked on growth, flexible electronics and biosensor applications using one-dimensional and two-dimensional nanomaterials.
I obtained extensive academic training before starting my professional career. From 2010-2012, I worked as Postdoctoral Research Associate in Prof. John Rogers' group (who is now at Northwestern University) in the Department of Materials Science Engineering at the University of Illinois at Urbana-Champaign. With Prof. Rogers, I worked on performance, variability, reliability and electroluminescence phenomena in carbon-nanotube based electronic/optoelectronic devices, and on the circuit design for epidermal electronics. Before starting my postdoctoral training, I completed (Direct) Ph.D. degree at Department of Electrical and Computer Engineering, Purdue University in May 2010 under the supervision of Prof. Muhammad Ashraful Alam. In my PhD research, I worked on theory and characterization of defect formation in nanoscale transistors. My background on electrical engineering was solidified in the Department of Electrical and Electronic Engineering at Bangladesh University of Engineering and Technology (BUET), from where I obtained my Bachelor degree in February 2004, securing the highest CGPA among the graduating students. During 2004-2005, I also worked as lecturer in the same department at Bangladesh University of Engineering and Technology (BUET).
I was born in Sylhet, Bangladesh and migrated to the United States in 2005 for higher studies and currently live in Dayton, OH.
