Greetings! My name is Nick Dygert, I’m an Assistant Professor of Planetary Science at the University of Tennessee, Knoxville. I use high-pressure, high-temperature experiments, numerical models and studies of natural samples to understand the formation and evolution of planetary interiors and crusts. My focus is the Earth and Moon, but as of late I am working on the thermal histories of chondritic meteorites and the dynamics of Mercury’s magma ocean as well. You can read more about my research here. Check me out on Twitter @NickDygert.
9-17-18: Postdoc Mike Lucas joined the group! Mike has a background in igneous petrology and astronomy and will be working on the thermal history of asteroids. Welcome, Mike!
9-7-18: NASA Solar System Workings proposal was selected! The grant will fund collaborative research with Hap McSween and Marc Hesse (UT Austin).
8-1-18: Dygert and Grambling traveled to Japan to participate in Oman Drilling Project core description activities aboard D/V Chikyu.
7-20-18: New paper on kinetic fractionation of noble gases in the mantle was published in Earth and Planetary Science Letters. Check it out!
5-25-18: Dygert gave a seminar at Case Western Reserve University entitled Early Evolution of the Moon: New Insights from the Lab.
5-3-18: Warren Ehrenfried, Chris Wilson and Joseph Nuttall joined the group to participate in summer research experiences funded by the Tennessee Space Grant. They are working on P-T-stress conditions recorded by peridotite xenoliths from kimberlite pipes, decarbonation and shock metamorphism of Flynn Creek impact structure target rocks, and the thermal history of the mantle beneath western North America.
4-18-18: Dygert presented a talk for the ORION Science and Astronomy Group entitled Early Evolution of the Moon.
3-30-18: Dygert gave a seminar at the University of Georgia entitled New Insights into the Accretion of Oceanic Lithosphere.
3-23-18: Megan Mouser and Nick Dygert attended the Lunar and Planetary Science Conference to showcase their research. Megan presented a poster on a lunar granite and Nick gave a talk on the thermal history of the LL chondrite parent asteroid.
3-8-18: Dygert traveled to Oman and joined the Oman Drilling Project science party.
2-22-18: Graduate students Megan Mouser and Nadine Grambling ran a dozen successful high-P-T experiments in a Paris-Edinburgh apparatus at Argonne National Lab, investigating the viscosity and structure of a mercurian magma ocean melt.
1-23-18: Dygert visited the CNRS laboratory in Toulouse, France to serve on Mathieu Rospabé‘s PhD jury and to present a talk on the formation of oceanic lithosphere. Mathieu successfully defended his impressive thesis, congrats Mathieu!
12-15-17: Dygert presented two talks at the American Geophysical Union meeting in New Orleans. The talks focused on the petrogenesis of lunar basalts and dynamic history of the Moon, and the formation of mylonitic mantle xenoliths from central Nevada.
11-29-17: Two graduate students are joining the group this spring!
Nadine Grambling is a PhD student interested in tectonics and rock deformation. Nadine is an alumnus of the University of Arizona and the University of New Mexico, where she did an MS with Karl Karlstrom. Welcome Nadine!
Megan Mouser is an MS student interested in planetary geochemistry and petrology. Megan was an undergraduate at the University of New Mexico and more recently a Lunar and Planetary Institute summer intern and experimental petrologist at Johnson Space Center. Welcome Megan!
11-21-17: New research on the viscosity of the lunar magma ocean led by Dygert was published in Geophysical Research Letters, and featured in a press release put together by UT Austin! The study argues that the Moon’s earliest flotation crust would have been relatively impure.
9-19-17: NASA Solar System Workings grant was selected for funding! We will investigate the rheology and convective history of the lunar mantle with rock deformation experiments.
8-14-17: Dygert presented an invited talk at the Goldschmidt Meeting in Paris in the session Lithosphere Evolution during Subduction and Collision.
7-3-17: A study coauthored by Dygert on lunar mantle convection was published in Geophysical Research Letters. Informed by recent experimental results, we found that the lunar mantle would have been stably stratified after cumulate mantle overturn.
5-1-17: New research on cooling of the mantle beneath mid-ocean ridges led by Dygert was published in Earth and Planetary Science Letters. The study was featured in a UT Austin media release! It argues that the mantle is cooled by hydrothermal circulation that extends all the way to the crust-mantle boundary beneath spreading centers.
