Overview

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:

  • Hydrogen and Abiotic Hydrocarbons: Molecules that Change the World, 2020, published in Elements
  • Hydrogen generation and iron partitioning during experimental serpentinization of an olivine-pyroxene mixture, 2020, published in Geochimica et Cosmochimica Acta
  • Hydrogen generation from serpentinization of iron-rich olivine on Mars, icy moons, and other planetary bodies, 2021, published in Icarus
  • The effect of pH on rates of reaction and hydrogen generation during serpentinization, 2020, published in Philosophical Transactions of the Royal Society A Mathematical Physical and Engineering Sciences
  • A dynamic microbial sulfur cycle in a serpentinizing continental ophiolite, 2020, published in Environmental Microbiology

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.
