Soil Scientist

Natural Resources Conservation Service

I am an environmental soil scientist interested in soil physics, biogeochemistry, and data science. I recently joined the USDA–Natural Resources Conservation Services in Texas as a soil scientist. Previously, I was a postdoctoral researcher at Stanford UniversityF, and before that a graduate student at the University of California-MercedT,A.

My research explore relationships between soil properties and the environment. I use traditional field- and lab-based research as well as modern techniques such as machine learning, geospatial analyses, and unmanned aircraft systems.
