About Me Publications

Engineering Geologist with the California Geological Survey (CGS) in the Los Angeles office working in seismic hazards and geologic mapping. Prior to joining CGS in 2009, I worked for a private geotechnical consulting firm for 11 years.

At CGS I am involved with active fault evaluation in southern California for the Alquist-Priolo Earthquake Fault Zoning Act. I've also created compilation geologic maps of several 7.5' quadrangles in the western Antelope Valley and I perform geologic and seismic hazard reviews of geotechnical reports for school & hospital construction for the Division of the State Architect (DSA) and the Dept. of Health Care Access and Information (HCAI), respectively.

I have participated in post-event response work collecting field data after the 2010 El Mayor-Cucapah earthquake, 2018 Montecito debris flows, 2019 Ridgecrest earthquake sequence, 2020 Lone Pine earthquake, and various post-wildfire debris flow/flooding events in southern California.
