Biography
I joined the USGS in 2015 as the coordinator of the Community for Data Integration (CDI). This position allows me to combine my interests in Earth science, technology, information management, and facilitation of communities of practice. I am also the project coordinator of the USGS Model Catalog.
Before joining the USGS, I spent time exploring fluvial seismology, debris flow erosion, creeping faults, alluvial fans, and atmospheric chemistry.
