This project applies advanced diffusion models to the CMS experiment's quark-gluon dataset, generating realistic multi-channel images (HCAL, ECAL, track) that reflect particle interactions in high-energy collisions.
Modern LLMs still have a long way to go when it comes to playing or understanding chess. This is an experimental approach that uses a combination of stockfish and an LLM to analyze and improve your chess moves.

We performed a comprehensive study applying quantum kernels to financial time‑series data, using a self‑curated Dhaka Stock Exchange (DSEx) Broad Index dataset. Implemented and benchmarked multiple quantum‐kernelized SVM models, identified the optimal kernel for our dataset, and demonstrated an empirical quantum advantage. To ensure robustness, we validated results against the Phase Space Terrain Ruggedness Index and projected the computational resources required to scale this approach for future practitioners.

Outreach
Mentoring and training the next generation of problem solvers
Founding member of the largest Competitive Programming Discord Community in Bangladesh, with over 11,000 active members.
Authored problems for BdMO contests with participation from over 40,000 students nationwide.
Contributed to the evaluation and selection of problems for the competition.
Trained 200+ students in competitive programming, preparing them for national and international contests.
Set weekly training contests, provided feedback, and helped form ICPC teams that attended the ICPC World Finals.
Mentored 50 high school students in foundational competitive programming, providing introductory classes on algorithms and data structures.
