Dr. Daniel Breecker

Biography

Daniel O Breecker is a Professor at the Jackson School of Geosciences, University of Texas at Austin, specializing in Earth and Planetary Sciences. His research primarily focuses on process-based understanding of the critical zone, particularly in relation to the formation of calcium carbonates, soils, and caves. Breecker's work aims to improve and develop paleoclimate proxies that understand changes in the climate and carbon cycle over various timescales. The Breecker Group investigates biogeochemical processes occurring near the Earth's surface, studying soils, paleosols, caves, and stalagmites to glean insights into the ancient Earth. Research areas extend to seasonal cycles and processes spanning hundreds to millions of years utilizing observations, mathematical models, and laboratory and field-based experiments to address a range of evolving questions. Breecker supervises graduate students focusing on topics like reactive transport dynamics, carbon emissions related to permafrost thawing, and the role of soils in deltaic wetlands. His profound contributions significantly advance the understanding of climate impacts on the Earth’s geochemical systems.
