Check out our group’s posters at the 2021 AGU Fall Meeting! All posters are in the DI25C session. Authors will be available during an online summary session from 2:00-3:00pm CT on Tuesday using this link. They will also be available for further discussion via zoom — links can be found by navigating to the pages linked below […]
A new collaborative paper is out in Space Science Reviews! This was the result of the ISSI Europlanet Workshop “Reading Terrestrial Planet Evolution in Isotopes and Element Measurements” held in October 2018 in Bern, Switzerland. The paper discusses geodynamical models of lunar origin in light of geochemical constraints from lunar and terrestrial rocks. For more about lunar […]
We are seeking candidates for a postdoctoral position in the noble gas laboratory (link to job ad). The position will focus on analyses of heavy noble gases in geological samples. Experience with high-precision noble gas mass spectrometry is preferred. Contact the PI (Parai) for additional information or with any inquiries.

This summer has brought two new review papers: One in Annual Review of Earth and Planetary Sciences that provides an overview of noble gas constraints on the origins of Earth’s volatiles, volatile delivery during accretion, the timing and extent of volatile loss, early-formed heterogeneities and their preservation over Earth history. One in Lithos that delves into recent noble gas […]
Our paper published in Nature presents a model of xenon (Xe) cycling between the deep Earth and surface reservoirs. Volatiles (such as water, carbon dioxide, nitrogen and the noble gases) are outgassed from the Earth’s mantle due to volcanic activity. Surface volatiles are also injected into the mantle at subduction zones in the present day, but […]
Savannah Rodriguez was awarded the EPS department’s 2018 Ernest L. Ohle, Jr. Award! Savannah’s senior honors thesis was titled Boron Isotopic Constraints on Chemical Transport into the Deep Earth. Congratulations, Savannah!
