PEER Annual Meeting 2023 Speaker Bio: Katerina Ziotopoulou is an Associate Professor in Civil and Environmental Engineering at the University of California at Davis. She received her PhD and MS degrees in Civil Engineering from UC Davis, and her undergraduate 5-year diploma degree in Civil Engineering from the National Technical University of Athens, Greece. Dr. Ziotopoulou specializes in geotechnical earthquake engineering with an emphasis on the investigation of ground failure due to earthquake-induced liquefaction and cyclic softening, and its mitigation. She combines the development of advanced numerical tools with multiscale experimental methods, the establishment of validation protocols that connect the two, and the upscaling to system-level analyses of case histories accounting for the spatial variability of soil deposits. She is the recipient of the 2021 ASCE Arthur Casagrande Professional Development Award, the National Science Foundation CAREER Award, and the ISSMGE TC203 2023 Young Researcher Award.
