  University of Maryland

  Sept 2017 - Aug 2021

  Research integrating geochemistry, petrology and field methods.Constrained the timescales of fluid migration in subduction zones using lithium isotope measurements combined with finite difference and Monte Carlo models of reactive transport. Leveraged apatite rare earth element and halogen chemistry to investigate elemental mobility and fluid-rock reaction. Developed a method for in situ measurement of Li isotopes and robust characterization of uncertainty using regression models. Physical Geology LaboratorySedimentation and Stratigraphy

  Kids Excelling in Math and Science

  Jan 2018 - Jan 2021

  Program Manager

  Manage a team of 15 mentors and oversee five successful grant applications totaling $2500 to local government and university organizations to fund the program.Articulate yearly learning outcomes, design weekly curriculum and organize quarterly field trips. Examples of hands-on activities and field trips include: nursing and planting native flora in local wetlands, measuring local tree cores to learn about past rainfall, and building waterwheels to understand energy production.

  Aug 2021 - now

  NSF Postdoctoral Fellow

  Dr. William Hoover has been awarded an NSF EAR postdoctoral fellowship ($174,000) to carry out research and educational plans at the University of Washington alongside mentor Dr. Cailey Condit. Dr. Hoover will investigate the role of water-rock reaction in producing the enigmatic seismic phenomena known as episodic tremor and slip (ETS) that can precede large, damaging earthquakes, particularly along subduction zone faults. This study will focus on rocks from Catalina Island (Southern California) exhumed from depths characteristic of ETS in modern subduction zones (e.g., Cascadia in Washington and Oregon). Integrated macro- and micro-scale structural and geochemical analysis will reveal how rock alteration by fluid flow yields deformation behavior characteristic of ETS. This work will provide important direct observations of rocks from ETS source regions and inform modern subduction zone monitoring and seismic research. Show less
