Anne Strader (Dr.) Staff scientist
anne.strader@dynafrax.com
​
Anne received her Ph.D. in Geophysics and Seismology from the University of California, Los Angeles in 2014. From 2015 to 2018, Anne worked as a postdoctoral researcher for the Helmholtz Centre Potsdam German Research Centre for Geosciences in the Section 2.6 Seismic Hazard and Risk Dynamics, focusing on the development and testing of physics-based earthquake forecast models. Her research concentrates on the role of static and dynamic Coulomb stress transfer in earthquake triggering, and she has developed physics-based seismicity models for Japan, California and Nepal, as well as collaborated on the development of the upcoming second version of the Global Earthquake Activity Rate Model (GEAR2). Shea has also participated in numerous earthquake forecast experiments with the Collaboratory for the Study of Earthquake Predictability (CSEP).
