Curriculum Vitae (pdf)
Toti came to Department of Geological Sciences in 2012 and focuses on understanding the transport of dissolved gases and free gas in the Earth. He uses stable isotope and gas chromatography techniques to develop this understanding. Projects include CO2-sequestration studies, dissolved methane in groundwater, and methane fluxes from the Arctic permafrost.
Toti Larson received a Ph.D. from the University of New Mexico Department of Earth and Planetary Sciences in 2003 with Dr. Zachary D. Sharp. There he studied oxygen isotope chemistry of aluminum silicate 'triple point' rocks in the Sangre de Cristo Mountains of New Mexico and Mt. Moosilauke, NH. He then completed a post doctoral fellowship at The University of Western Ontario with Dr. Fred Longstaffe where he developed an in situ laser system to measure oxygen and carbon isotopes in modern deer cortical bone. Toti then worked for 7 years as a Technical Staff Scientist at Los Alamos National Laboratory where he studied nuclear and chemical forensics, environmental monitoring, CO2 sequestration and enhanced oil recovery.
Areas of Expertise
Dr. Larson is a stable isotope geochemist specializing in novel methods of light isotope measurement that include silicate laser fluorination, compound-specific carbon isotope measurement, and gas chromatography. His current research focuses on developing tracers to probe shallow (vadose zone) and deeper CO2 sequestration and unconventional reservoirs. He integrates experimental flow through column experiments with diffusion-advection modeling to understanding the behavior of tracer compounds in a variety of substrates. He also couples light isotope fractionation with these tracer studies to understand molecular interactions during transport.
, Ph.D., expected 2016
I am a PhD candidate studying the Bravo Dome carbon dioxide reservoir near the Texas-Oklahoma-New Mexico border. My work involves incorporation of stable and radioactive isotope geochemistry, reservoir engineering and multiphase flow, and petrophysics and geostatistics. I am interested in incorporation of data and models from these varying disciplines to better understand subsurface fluid flow.
