"Precision in the nanoscale defines performance at the macroscale."

I am a Ph.D. student in Electrical Engineering at Virginia Tech, focusing on semiconductor materials, devices, fabrication, and circuit–device co-design.

My work bridges materials and device physics with integrated circuit and photonic applications.
Before joining Virginia Tech, I completed my M.S. at Auburn University and B.S. at Shahjalal University of Science and Technology (SUST), Bangladesh.

🧪 Research Overview
