Dr. Alyssa Abbey, Assistant Professor

California State University Long Beach

Bio: Dr. Alyssa Abbey is an Assistant Professor in the department of Geoscience at California State University Long Beach (CSULB). She studied Geology and French at the University of Arizona and then completed her PhD at the University of Michigan researching continental rifting and fault growth using various geological dating methods. Her postdoctoral work, at the University of California, Berkeley, took her into new fields, studying active faults in Argentina, and water-rock interactions combining geochemistry, geochronology, and modeling. At CSULB, her research is split into research on tectonics and fault processes as well as geoscience education accessibility. Check out her children’s graphic novel on how mountains are made and change over time! (More information can be found on her website:
