St Louis, Missouri, United States
Research Assistant- Determined earthquake locations, depths, and focal mechanisms using land and ocean bottom seismic data to constrain lithosphere stress models at the Tonga subduction zone.- Developed a technique to study reflections off the Earth's D'' layer above the core-mantle boundary.- Modeled seismic energy focusing antipodal to large planetary impacts with emphasis on investigating the origin of the Tharsis Rise on Mars and hilly/lineated terrain on Mercury.Teaching Assistant- Developed/taught labs, created course websites, graded assignments/exams, and delivered occasional lectures.1) Hydrology (2005)2) Exploration & Environmental Geophysics (2003) Taught field exercises in gravity, magnetic, electrical, and seismic refraction methods.3) Epic of Evolution: Life, the Earth, and the Cosmos (2001) Interdisciplinary course in Biology, Physics, and Earth Science departments. Won the Carl Tolman Teaching Assistant Award.4) The Solar System (2000)Field Assistant- Team member for 4 NSF-funded IRIS-PASSCAL expeditions to install and maintain broadband seismic stations for targeted study of the Earth's interior. Worked in small teams to coordinate logistics for ground, ice, sea, and air scientific field operations at over 80 stations across the globe under strict time frames constrained by hostile weather conditions.1) MARIANA: Mariana Subduction Zone Seismic Imaging (2003)Installed 16 stations on 8 Northern Mariana islands. Member of team to first witness and report the eruption of Anatahan volcano.2) TAMSEIS: Trans-Antarctic Mountains Seismic Experiment (2002)Serviced 31 stations on the Antarctic plateau, dry valleys, and coast regions.3) SAFT: Seismic Arrays in Fiji & Tonga (2001, 2002)Installed 14 stations on 4 Fiji Islands. Returned solo in 2002 to service 27 stations on 4 Fiji and 6 Tonga islands.4) FLED: Florida to Edmonton Broadband Seismic Array (2001)Installed 26 stations in FL, GA, AL, MO, IA, SD, ND, MT, SK, and AB.
