Work Experience

AI Researcher at Northwestern University

January 1, 2025 - Present

Developed a PPO-based reinforcement learning framework to unlearn restricted content from LLMs while preserving fluency and coherence. Engineered a hybrid reward system to suppress specific tokens without causing catastrophic forgetting. Initiated a project on automated LLM-based grading using rubrics, prior grading patterns, and course material. Utilized PyTorch, Hugging Face Transformers, prompt engineering, PEFT, LoRA, and Reinforcement Learning while documenting experiments for collaborative research.

Data Science Intern at Allegion

December 31, 2024 - July 18, 2025

Collaborated with cross-functional teams to analyze warranty claims using PySpark workflows and LLM-based extraction techniques. Delivered insights across geography, product category, and time using OpenAI embeddings, clustering methods, and exploratory data analysis. Proposed mitigation strategies leading to over 80% reduction in recurring claims by automating root cause analysis and categorization. Worked with Python, NumPy, Pandas, Jupyter Notebooks, Power BI, and OpenAI API for data processing, visualization, and modeling.

AI Research Intern at Northwestern University

September 30, 2024 - July 18, 2025

Designed and deployed a dual-mode LLM pipeline (live and batch processing) to automate key data extraction from global poverty research PDFs, reducing manual effort by over 60%. Built and containerized front-end and back-end services using Docker, with model integration (Llama 3.1 via AWS Bedrock and GPT-4) for answer extraction based on user-selected accuracy levels. Engineered scalable AWS-based infrastructure with Lambda, S3, MongoDB, and CI/CD pipelines using GitHub Actions and CodeDeploy for real-time deployment and document processing.
