I am a hydrogeologist interested in how fluids interact with and can induce earthquakes and how groundwater factors into water resources. I am currently looking for M.S. and Ph.D. students for fall 2021.
Over the last decade, injection-induced seismicity has gained attention from scientists and the public alike. While only a small percentage of wastewater disposal wells have induced seismicity associated with them, the induced seismicity can cause a variety of problems including damage to property. I use numerical models to investigate the physical mechanisms that induce seismicity and how these relate to mitigation. I have explored the role of wells at large distances from the induced earthquakes to trigger the seismicity and the potential to use geodesy data that measures the surface deformation near an injection well to calibrate pore pressure models. My current work is focused on the role of earthquake interactions in triggering injection-induced seismicity.
I have a particular interest in increasing inclusion and accessibility in the geosciences. This includes creating accessible field work. In addition, I look at how teaching can be improved to promote accessibility in the classroom and course materials.
