AI Researcher (IEEE & Springer Published) | NLP, LLMs & Material Science | IIT Kharagpur

Profile Summary

I am an AI researcher and engineer with a strong academic foundation from IIT Kharagpur (Chemical Engineering + AI Minor). I specialize in bridging the gap between scientific domain knowledge and advanced Machine Learning. My research portfolio includes works published or accepted in IEEE and Springer (LNAI), as well as papers currently under review in high-impact journals like ICARUS and ACS Applied Materials. I have successfully delivered R&D projects for industry leaders like DevRev and Eightfold.AI.

My Core Expertise:

- Scientific ML & Material Informatics: I apply ML to complex physical data. I developed a pipeline for analyzing Chandrayaan-2 lunar surface data (increasing resolution by 10x), a study currently submitted to ICARUS. Furthermore, I developed a framework to predict ionic conductivity using Mat2Vec embeddings, which is currently under preparation for submission to ACS Applied Materials & Interfaces.

- Large Language Models (LLMs) & NLP: I specialize in Fine-tuning, RAG, and Agentic workflows. At DevRev, I designed "RTaC," a generalized framework for tool integration, which was published in NSLP 2024 (LNAI 14770). I also developed "SATYA," a RoBERTa-based recommendation system for HR tech, published in IEEE RAAI 2024.

- Data Security & Encryption: I created "CipherBERT," a systematic framework for running Transformer inference on Homomorphic Encrypted data. This work has been accepted for publication in IEEE TPS 2025.

I am available for complex data science projects, implementation of research papers, and building custom AI pipelines for scientific or financial data.
