Power System Operation and Service Design – 80-hour Training Conducted by KUET under the EDGE Project, Bangladesh Computer Council (BCC), ICT Division. The training focused on practical power-system operation and service planning, with hands-on exposure to AutoCAD Electrical, ETAP, MATLAB/Simulink, PowerWorld Simulator, and PSS/E, supported by project-based learning and industry insights.

Undergraduate Thesis

“Performance Analysis of a Taguchi-Optimized SCF-SPR Sensor via Dual Interrogation for Broad Range Refractive Index Detection.” Proposed and analyzed a suspended-core fiber surface plasmon resonance sensor supporting both confinement-loss and birefringence interrogation methods. FEM simulations and Taguchi optimization were used to improve sensitivity, resolution, and applicability for biomedical and chemical sensing.
