University of Waterloo

Graduate Researcher (ML/NLP)
Sep 2022 - January 2025, Waterloo, ON, Canada

Applied NLP and ML techniques to real-world data, with a primary focus on developing LLM-powered pipelines for analyzing conversational meeting data and addressing complex, data-driven challenges.

  • Utilizing diverse data mining, ML, and NLP libraries such as pandas, scikit-learn, PyTorch, PySpark, Tensorflow, Hugging Face Transformers, LangChain to analyze and prepare data, perform feature engineering, model training, and optimization.
  • In the NLP domain
    • Worked extensively on tasks such as text classification, information extraction, topic modeling, and prompt engineering, with a focus on analyzing conversational meeting data.
    • Fine-tuned open-source language models (e.g., Mistral, LLaMA 3) for downstream tasks, optimized inference pipelines, and applied retrieval-augmented generation (RAG) techniques using LangChain to enhance context-aware performance.

  • Additionally, contributed to solutions for complex spatiotemporal data problems, applying machine learning techniques and domain knowledge to tackle real-world challenges.

  • Presented a component of my work at the 11th International Conference on Design Computing and Cognition (DCC) 8-10 July, 2024, Montreal, Canada. Towards AI-Assisted Protocol Analysis in Design Research. doi: 10.1007/978-3-031-71918-9_3
