Bio


Before coming to Stanford Geophysics, Karissa has lived in Minnesota, South Dakota, Pennsylvania, and Texas. Her work is inspired by the human connection to the planet: how humans affect the subsurface environment and how the response, in turn, affects humans and ecosystems. When not working on her research, Karissa is actively involved in SE3 Wellness Initiatives, DEI efforts, and mentoring/teaching opportunities. She loves water sports (both open and ice), animals, and creating music.

Current Research and Scholarly Interests


Karissa explores the use of interferometric synthetic aperture radar (InSAR), a remote sensing tool that measures mm-scale surface deformation at a resolution of 5-20 m, to study the subsurface response to fluid extraction and injection at wells, including induced seismicity, aquifer compaction, and changes in fluid flow. She also studies the InSAR signal with the goal of generating accurate time series.
