UMD Planetary Volcanism Laboratory
Welcome to the University of Maryland Planetary Volcanism Laboratory!
We study volcanoes on Earth and beyond.
Research Questions
Where did Earth's water come from?
What factors control volcanic eruptive style on the Earth and other planetary bodies?
How fast does magma cool within the volcanic conduit? How fast does magma rise from source to surface?
Can we link petrologic markers of magma ascent to the seismic record at active volcanoes?
Research Keywords
Volatiles
Silicate melts
Olivine
Diffusion
Moon
Melt inclusions
Conduit processes

The first UMD Volcano Camp will run this June 24th - 28th! We will be hosting local high school students and Terrapin Teachers for a week of volcano activities and hands-on research. Thanks to NSF CAREER for support.
March 2024
Euan's paper about 3D diffusion of water in melt inclusion-bearing olivine phenocrysts has just been published in G-cubed. Congratulations Euan!
February 2024
Liam just published his third first-author paper! He studied the H content of acapulcoite-lodranite clan meteorites. These meteorites are special because they capture the transition from unmelted nebular sediments to melted planetesimals. Read more here!
August 2023
Congratulations to Liam on his latest paper in EPSL about the H content of aubrites!
July 2023

New paper alert: Degassing of early-formed planetesimals restricted water delivery to Earth, published in Nature.
January 2023
Megan has received a National Science Foundation CAREER award! We are excited to develop a water-in-feldspar crystal clock, and we look forward to meeting local high school students for an annual Volcano Summer School!
November 2022
Liam's paper about the water content of the ureilite parent body has been published in GCA! The paper is available here.
August 2022
New graduate students Sumedha Desikamani and Kathy Stepien have arrived on campus - welcome! Sumedha will be constraining water partitioning and diffusion behavior in plagioclase, and Kathy will be working with Sarah Penniston-Dorland and me to measure water in garnet.
Undergraduate Researcher MaKayla Etheredge has joined the University of Oregon as a graduate student in volcanology - congratulations MaKayla!
September 2021
Liam's NASA proposal has been selected for funding! Liam is now a Future Investigator in NASA Earth and Space Science and Technology. He will use this three-year award to study the origin of inner solar system volatiles. CONGRATULATIONS LIAM!!!
August 2021
New graduate students Kyle Kim and Cosmo Varah-Sikes have arrived on campus - welcome! Kyle will be working on magma ascent at Cinder Cone (Lassen Volcanic National Park) and Cosmo will be working with Jessica Sunshine and me on some mysterious spinel-rich lunar volcanic deposits.
January 2021
New graduate student Silvia Castilla Montagut has arrived in College Park - welcome Silvia!
Liam has been selected to receive an Outstanding Graduate Assistant Award - congratulations Liam!
August 2020
New paper accepted in Frontiers about magma pressure-temperature-time paths during mafic explosive eruptions. Make sure to check out the rest of the 'crystal archives of magmatic processes' collection!
June 2020

August 2019
January 2019
Goldschmidt abstract submission is open! Check out session 06j: "Do Magmatic Systems Play by our Rules? Translating from an Equilibrium Rulebook into a Kinetic Playbook". We will be discussing disequilibrium processes in magmatic systems, including diffusion chronometry (crystal clocks). Deadline is 31st March.
August 2018
AGU abstracts are due 1st August! Please consider submitting your abstract to session V039: "The Time is Ripe: Advancements of Diffusion Chronometry in Igneous and Metamorphic Systems".
Megan is an invited speaker at the upcoming pre-Goldschmidt workshop about melt inclusions.
June 2018
Megan was an invited speaker at the PACROFI conference at Rice University.
