Andrea Donnellan is manager of JPL’s Instrument Systems Implementation and Concepts Section. Still an active researcher Donnellan collects and analyzes geodetic data to model deformation of mechanical Earth processes and study cascading geohazards. She has applied Interferometric Synthetic Aperture Radar (InSAR/UAVSAR), Global Navigation Satellite System (GNSS), and stereophotogrammetry or Structure from Motion (SfM) from small uninhabited aerial vehicles (sUAS) to studying the underlying dynamics of earthquake fault systems, plate boundaries, landslides, and wildfire/debris flows cascades. Donnellan leads JPL’s Near-Surface Airborne Instruments Laboratory (N-SAIL). She is PI of QUAKES-I developing an airborne imaging suite of visible and SWIR cameras for stereophotogrammetry and improving UAVSAR capability to study and respond to natural disasters. Donnellan is on the NISAR Science Team. In 2021-2021 she led NASA’s Surface Topography and Vegetation Incubation Study, which released its study report in June 2021. Donnellan is Principal Investigator of NASA's GeoGateway project of which the predecessor project QuakeSim won NASA’s Software of the Year Award in 2012. She was editor of the American Geophysical Union's Earth and Space Science Journal, Vice Chair of the UNAVCO board, and was President of the American Geophysical Union's Nonlinear Geophysics Section. Donnellan produced one of the first papers to interpret GPS data in terms of crustal deformation and fault processes. She demonstrated that GPS measurement of surface deformation could be used to infer geometry and rate of slip on buried faults. More recently she used geodetic imaging data to show a broad pattern of crustal deformation in a region surrounding the 2014 M5.1 La Habra earthquake that was much larger than expected. Several shallow structures were responsible for producing the observed deformation. She also showed that postseismic motion north of the 2010 M7.2 El Mayor - Cucapah Earthquake could be explained by afterslip on the main fault rupture and that postseismic UAVSAR observations could fit using fault friction laws. Donnellan has been Deputy Manager of JPL's Science Division and Area Co-Lead for Natural Disasters in NASA's Applied Sciences Program. She taught Introduction to Geodetic Imaging as a lecturer at California State Polytechnic University - Pomona. Donnellan has conducted field studies in California, in Antarctica, on the Altiplano of Bolivia, in Mongolia, and on Variegated Glacier in Alaska. She has been a geophysicist at JPL since 1993. Donnellan has degrees in Geology (BS Ohio State University, 1986), Geophysics (MS and PhD Caltech 1988 and 1991), and Computer Science (MS University of Southern California, 2003). She held a National Research Council postdoctoral fellowship at NASA's Goddard Space Flight Center from 1991-1993. Donnellan has received the Presidential Early Career Award, the MUSES of the California Science Center Woman of the Year Award, Women in Aerospace Award for Outstanding Achievement, JPL's Lew Allen award, several NASA Space Act Awards, the Antarctic Service Medal, and has been a finalist in the astronaut selection process three times. Donnellan has a glacier in Antarctica named after her for her work on that continent.
