We use noble gas geochemistry to study the physical and chemical processes shaping the surfaces of Earth and other planets.

 Some of the scientific problems our work addresses include:

  • how the Earth’s climate changed during the geologic past
  • how tectonic and geomorphic processes interact to shape topography
  • the impact history of the Moon and other planetary bodies in the inner Solar System
  • rates of volcanism and interactions between volcanism and Earth’s climate system

We also conduct basic experimental research on the kinetics of noble gas diffusion in minerals, which has broad significance across both Earth and planetary science disciplines. To learn more about the current and recent research efforts of T@P, check out our Research page.

Moe's paper is published in Meteoritics and Planetary Science

January 2025: PhD student Moe Mijjum's paper Using X-ray computed microtomography (μCT) to determine subsample-specific cosmogenic noble gas production rates of E (enstatite) chondrites has been published in the journal Meteoritics and Planetary Science. Congratulations, Moe!

T@P Lab becomes part of PRECISE, a NASA-funded Planetary Science Enabling Facility

December 2024: Our lab is now part of PRECISE, which stands for Purdue Resources Empowering Coordinated Investigations for Sample Exploration. This NASA-funded Planetary Science Enabling Facility provides no-cost access to 13 world-class laboratories, serving research spanning three themes: (1) Solar System Isotopes and Chronology, (2) Coordinated Composition, Microstructure, and Magnetism, and (3) Bridging the Gap Between Remote Observations and Laboratory Science. Dr. Marissa Tremblay leads the Solar Sytem Isotopes and Chronology theme. Sample analysis at PRECISE is free for outside users. Potential users interested in obtaining noble gas analyses through PRECISE should reach out to Dr. Marissa Tremblay about capabilities and how to apply.
