His current research interests include the multi-disciplinary field of urban earthquake engineering. This field combines the expertise of geotechnical and structural earthquake engineering, engineering seismologists, public policy experts, and decision-makers to improve the seismic resiliency of urban areas. Dr. Mason uses physical modeling techniques such as centrifuges, shaking tables, laminar soil boxes, and cyclic laboratory equipment, as well as numerical modeling tools including FLAC, OpenSees and PLAXIS. Additionally, Dr. Mason is interested in the fields of sustainable geotechnical engineering and geotechnical engineering education.
