Overview

• Designed and delivered a lecture on chemical exposomics covering mass spectrometry fundamentals, environmental health applications (PCBs, PFAS), and the exposomics framework.
• Developed a complete, reproducible R workflow using publicly available LC-MS metabolomics data, guiding students through data cleaning, normalization, dimensionality reduction, and visualization.
• Prepared accompanying lecture slides and annotated teaching materials to support independent student learning.

The teaching materials are available in my GitHub repository.
