Manoochehr Shirzaei

Associate Professor

I am a geodesist/geophysicist specialized in satellite geodesy, inverse theory, signal processing, modeling techniques, and physics of crustal deformation. Conducting a comprehensive interdisciplinary research program, I aim my research effort to improve understanding of the underlying mechanism associated with seismic and aseismic faulting processes, the evolution of crustal stresses and seismic hazard due to fluid extraction and disposal, changes in groundwater and surface water resources, and impacts of relative sea-level rise on coastal areas. 
Though the range of topics may appear diverse, the common theme is an attempt to develop a better quantitative understanding of physical processes operating in the Earth. To this end, I develop sophisticated space-, air-, and ground-based monitoring techniques to measure subtle deformation signatures at unprecedented spatial and temporal resolutions. Linking surface observations to the underlying physical process, I also develop a variety of physics-based numerical and analytical models. My utmost goal is to help with mitigating adverse impacts of natural and anthropogenic hazards through improved understanding of mechanisms as well as educating a new generation of scientists and bringing awareness to the public.
