Dr. Toti Larson
Dr. Toti Larson is a Research Associate Professor at the University of Texas at Austin, Jackson School of Geosciences, Bureau of Economic Geology. He applies geochemistry, geology, and machine learning tools (CorePy) to develop predictive subsurface characterization models for conventional and unconventional energy systems. As co-Principal Investigator of the Resource Assessment of Mudrock Systems (RAMS) consortium, Toti works directly with energy companies to identify knowledge gaps and execute subsurface geology and petrophysics characterization projects that leverage the RAMS research team's strengths. He is also Director of the IsoCore Stable Isotope Geochemistry Laboratory and Principal Investigator of multiple projects investigating subsurface hydrogen production from iron-bearing rocks — part of a broader research effort to understand the behavior of hydrogen, noble gases, and carbon dioxide in the Earth.
