As of 2021, Montañez is the director of the UC Davis Institute of the Environment.
Craig E. Manning is a professor of geology and geochemistry in the Department of Earth, Planetary, and Space Sciences at the University of California, Los Angeles, where he served as department chair between 2009 and 2012. Manning's research interests include water chemistry, thermodynamics, gas chemistry, geochemistry, igneous petrology, and metamorphic petrology.
Dimitri Alexander Sverjensky is a professor in Earth and Planetary Sciences at Johns Hopkins University where his research is focused on geochemistry.
Rajdeep Dasgupta is a professor of Earth, Environmental, and Planetary Sciences at Rice University. In his research, he studies the role of subsurface melting and magma on the origin and evolution of the Earth and other terrestrial planets.
Kevin C. A. Burke was a geologist known for his contributions in the theory of plate tectonics. In the course of his life, Burke held multiple professorships, most recent of which (1983-2018) was the position of professor of geology and tectonics at the Department of Earth and Atmospheric Science, University of Houston. His studies on plate tectonics, deep mantle processes, sedimentology, erosion, soil formation and other topics extended over several decades and influenced multiple generations of geologists and geophysicists around the world.
Penelope King uses geochemistry and cosmochemistry to study planetary processes to better understand past and future planetary environments, and what this information may tells us about climate change. She is a professor at the Australian National University (ANU) in the Research School of Earth Sciences (RSES). King holds many awards, including Fellow of the American Geophysical Union and the Mineralogical Society of America in 2019, and winning the AGU Joanne Simpson Medal for Mid-Career Scientists the same year. She currently leads a research group examining surface and interior processes on planetary bodies.
T. Mark Harrison is an isotope geochemist based in California. He is Distinguished Professor of Geochemistry in the Department of Earth, Planetary and Space Sciences, University of California – Los Angeles.
Robert "Bob" J. Bodnar is an American geoscientist. He is a University Distinguished Professor and C. C. Garvin Professor of Geochemistry at Virginia Tech.
Ian Dalziel is a Scottish geologist who pioneered the study of pre-Pangaea plate tectonics and the theory of supercontinent cycles on Earth. In particular, he is known for geologic fieldwork in the southern Andes, the Scotia Arc, South Georgia and Antarctica. His discoveries include evidence for the timing of the separation of South America from Antarctica and the beginning of the Antarctic Circumpolar Current.
Laura J. Crossey is an American hydrologist and geochemist and Distinguished Professor of Earth and Planetary Sciences at the University of New Mexico (UNM).
