Lisa Grant Ludwig is an Associate Professor in Public Health at the University of California, Irvine and former Associate Director of the California Institute for Hazards Research. She earned a Ph.D. in Geology with Geophysics and dual M.S. degrees in Geology and Environmental Engineering from Caltech, and a B.S. from Stanford in Applied Environmental Earth Sciences. Her research interests include natural hazards, paleoseismology, active faults, seismic hazard, environmental health and geology. Her research group addresses natural hazards and disasters from a geologic perspective, with emphasis on earthquakes. The group focuses on defining the potential for large earthquakes, and working collaboratively on developing forecasts, hazard models and effective responses. Results of the work are applied for disaster preparedness planning, structural design, land-use planning, seismic risk assessment and public education about earthquake hazard.
