Research Interests

Undergraduate Thesis

Development of a Multimodal Medical Assistance Chatbot for Domain-Specific Applications

Supervised by Prof. Mohammad Ariful Haque, with collaborators Tanvir Ahmed Khan and Ismam Nur Swapnil.

Developed a dermatology-focused multimodal medical assistant by fine-tuning a vision-language model on DermNet, using GRPO and DPO for reasoning and conversational alignment, integrating DINOv2 and knowledge-graph-based RAG for diagnostic precision, and applying structured pruning for efficient deployment.
