Director of Geosciences and Associate Professor of Geochemistry

I research the highly complex processes that connect land and natural waters and play a fundamental role in sustaining life on Earth. The part of land that sustains all life is now often termed the Critical Zone (CZ), which is a powerful framework for interdisciplinary science and education contexts where I use my background in geosciences, mineralogy, biogeochemistry and geomicrobiology, as well as my deep interest in education to study how climate change, pollution, and inequity impacts water quality and water security. My work is collaborative, and I enjoy working with partners from different backgrounds, perspectives and epistemologies to tackle challenges in land and water research and education. In our everyday work we use field observations, experiments, and data science, integrate our findings in STEM education, grapple with living into our values of diversity, equity, and community and look to team science for help with all of it. My teaching integrates this interdisciplinary setting (e.g. GEOL1040) and uses hands-on approaches to understand Deep Earth and mineralogical processes (e.g. GEOL2105&3105), surface environmental dynamics (e.g. GEOL2405&3405), and land water interactions (e.g. GEOL4405 & GEOL5405).
