Himel Das

Built the Python analysis pipeline for the 7-student Konatori-135 team (my part: event selection, invariant-mass reconstruction, and fitting; teammates handled simulation cross-checks and the proposal write-up) and reconstructed π⁰ → γγ from sample calorimeter data across carbon, aluminium, and lead targets. Our fit gave a π⁰ peak at 135.0 MeV/c² and α = 0.735 ± 0.038 (energy-scale factor from the calibration fit); code at github.com/hello2himel/bl4s-konatori-135 .

Designed a networked hospital call system using ESP32, OLED displays, physical call buttons, MQTT/TLS, FastAPI, and PostgreSQL. Prototype stage: bench-tested with a few devices; designed to scale toward approximately 100 connected devices.

Taught physics to Grades 9–10 students, emphasizing physical intuition, conceptual reasoning, and demonstrations beyond standard classroom materials.

Develops hands-on STEM outreach through SciencePreach for rural schools and produces Feynman Files, educational science content focused on intuitive explanations; conducted demonstrations in Bogura, Sundarbans, and Cox's Bazar using locally sourced materials.

Organized workshops and olympiad training sessions; coordinated school participation in national competitions; established peer tutoring in physics and mathematics.
