Thomas M. McCollom is a researcher affiliated with the University of Colorado Boulder in the United States. Their work primarily spans the fields of Physics and Astronomy, Environmental Science, and Earth and Planetary Sciences, with a focused presence in subfields including Astronomy and Astrophysics, Environmental Chemistry, Geophysics, Molecular Biology, and Ecology.
Their research explores key topics such as Astro and Planetary Science, Methane Hydrates and Related Phenomena, Planetary Science and Exploration, Microbial Community Ecology and Physiology, Geological and Geochemical Analysis, Paleontology and Stratigraphy of Fossils, along with Geology and Paleoclimatology Research.
Recent notable publications include:
McCollom frequently publishes in venues such as Geochimica et Cosmochimica Acta, Abstracts with programs - Geological Society of America, American Mineralogist, Goldschmidt2022 abstracts, and Zenodo (CERN European Organization for Nuclear Research).
Collaborative efforts feature several frequent co-authors, including Tori M. Hoehler, Frieder Klein, Bruce M. Moskowitz, P. Sølheid, and Matthew O. Schrenk.
The research interests reflected in McCollom's work focus on processes related to serpentinization, hydrogen generation, and the chemical energy sources relevant to planetary and environmental sciences. Their studies include reaction rates, geochemical cycling, and microbial interactions in serpentinizing environments, often linking geological phenomena with broader planetary and astrobiological contexts.
