• [Machine Learning | GUI] Created an open-source Python-based computer vision toolkit (UrbanTrace) to detect urban changes at the building level using high-resolution aerial imagery, incorporating deep learning models (YOLO, Siamese Networks), and integrated the tool into a QGIS plugin with PyQt.
• [Computer Vision] Processed and analyzed large-scale geospatial datasets (6.5M buildings across 35,000+ square miles) using Python, PyTorch, OpenCV, and GIS frameworks.
• [LLM] Use Large Language Models via LangChain—including GPT-4, Claude 3, Qwen2, and LLaMA 3—to conduct sentiment analysis on 10,000+ Twitter/X posts, evaluating public perception of New York City’s congestion pricing plan.
• [Causal Inference] Use logistic regression, spatial econometric analysis, and an explainable machine learning model (XGBoost+SHAP) to examine urban development trends and demographic shifts with various Python packages
• [Supervision] Provided data analysis (Python and R), machine learning, and GIS support to lab researchers and supervised undergraduate and master’s students.
