Biography

Alyssa Valdez

Teaching Pathway Postdoctoral Faculty, Environmental and Ocean Sciences

  • PhD, University of California Riverside, Environmental Sciences
  • BS, University of California Merced, Earth Systems Science

Alyssa Valdez is an environmental scientist who studies where greenhouse gases come from and how to monitor the effectiveness of solutions created to mitigate them. Her research combines airborne and satellite imaging spectrometry, ground-based gas instrumentation, and stable isotope analysis to trace methane and nitrous oxide back to their specific sources on California dairies. She works to get scientific results out of journals and into the hands of the communities most affected by climate change, an approach she carries into the classroom through courses on maps, data, and climate.

Areas of Expertise

Greenhouse gas emissions from agriculture and the food system, Airborne and satellite remote sensing of methane point sources (AVIRIS-NG, EMIT, Sentinel-2), Stable isotope geochemistry (δ¹³C-CH₄, δ¹⁵N) and isotope ratio mass spectrometry, Field gas flux measurement (Picarro, LI-COR, and LGR analyzers; static and dynamic chambers), Geospatial analysis (ArcGIS Pro, QGIS, R)
