A crazy and busy year has come and gone since I last updated the website and the EPIC lab news page!
Amidst weathering the COVID-19 pandemic, as well as racial, economic, and climate crises in the US, we've managed to find some solace in doing some science. Perhaps the biggest news is that EPIC graduate students Meghan Guild (PhD), Kara Brugman (PhD), Hannah Shamloo (PhD) and Mitch Phillips (MS) have all graduated this past year!!! Definitely a heroic effort in these times! We're going to miss them desperately but are so excited for all the wonderful things they are off to next and the bright futures that await them! You can also read a nice profile on Meghan, Hannah and Kara when they graduated from ASU here: https://asunow.asu.edu/20200428-‘epic’-team-scientists-graduates-asu. Also a big congrats to a number of EPIC second project students who had big wins this year as well; Alicia Johnson and Chad Ostrander for defending their PhD's, and Srinidhi Ravi, Mara Karageozian, and Samantha Jacobs for passing their qualifying exams!
We've had a slew of new papers come out too, covering topics from Yellowstone to arc magmas and more which you can check out here. Current EPIC PhD students Felix Ishimwe and Jessie Bersson have been hard at work learning about the history of volcanism in Colombia and the frequency of magma recharge at Mt. St. Helens, respectively. Both of them will be presenting their new work at the virtual AGU 2020, so look for their presentations there. And EPIC undergraduate researcher Jax Webb is busy working on querying characteristics of past dome-forming eruptions in an effort to improve eruption forecasting. Impressive all while working from home!
Other good news is that I secured tenure at ASU this summer and also stepped into the role of Associate Director for an Inclusive Community with the School of Earth & Space Exploration, to work on promoting equity within our unit's systems and processes. As part of this I am leading SESE's SESE Justice-Equity-Diversity-Inclusion (JEDI) Task Force and a graduate class on the same subject.
In addition, I contributed to this ASU Now piece answering your "burning questions about volcanoes," which may be a fun read for those less familiar with volcano science.
Sending our best to everyone out there as we take this unprecedented time, one day at a time,
Christy Till, EPIC Head Magma Maker (mostly from home these days)
There's a slew of new papers out of the EPIC lab this summer...
EPIC grad student Karalee Brugman & PI Christy Till's 2019, cpx-liquid geothermometer for silicic systems was officially published at American Mineralogist
EPIC grad student Hannah Shamloo & PI Christy Till's 2019 paper on the triggering mechanism for the Lava Creek Tuff super-eruption at Yellowstone was published at Contributions to Mineralogy & Petrology
PI Christy Till and co-authors 2019 zircon geochronology & petrochronology paper on the magmatic system evolution in the aftermath of the Lava Creek Tuff super-eruption at Yellowstone is now available online at G-cubed.
....with even more to come soon!
This summer many EPIC lab members were busy trying to wrap up MS & PhD projects and start writing postdoc proposals as they look toward graduation this Winter and Spring. We attended a variety of great conferences and workshops including the volcanology field school at Katmai volcano in Alaska, the 2019 CIDER on Volcanoes, the Solid Earth Gordon Conference and the Earth Educator's Rendezvous, and will be presenting at the upcoming Goldschmidt conference in Barcelona and the Geological Society of American meeting in Phoenix AZ in August and September.
We were also excited to learn that a NSF FRES grant to work on the evolution of the Colombian arc and continental lithosphere from Miocene to present was funded this summer, after our preliminary work there supported by an Smithsonian Tropical Research Institute - ASU grant showed some promising and intriguing outcomes. So stay tuned for a lot more about our work on volcanism in Colombia!
And last but certainly not least, the EPIC lab is especially excited to welcome two new grad students starting this Fall, Jessie Bersson and Felix Ishimwe! We're so excited to have them on board and for all the exciting science they will be doing with us.
Lots of new EPIC lab research rolling off the presses these days!
EPIC lab PhD candidate Kara Brugman & Christy Till's paper in American Mineralogist on a new clinopyroxene-liquid geothermometer is now available as a preprint here.
Christy Till and co-author's Nature Communications (open access) paper on causes of diversity in volcanic behavior in now available here.
EPIC lab alumni Kayla Iacovino & Christy Till's paper & code on a new density calculator for magmas is available here.
EPIC lab PhD candidate Hannah Shamloo & Christy Till's paper in Contributions to Mineralogy and Petrology on the run up to Yellowstone's Lava Creek Tuff Eruption is in press, and will be available shortly.
Stay tuned for more coming soon!
It's been a great year with lots to celebrate as the school year comes to a close, some highlights include:
Nice article on exoplanet science out today that includes our work on making exoplanet mantle and magma compositions in the EPIC lab. Read it here!
EPIC celebrated a lot at the end of the 2016-2017 school year, including:
Congrats to everyone for all their hard work this year!
We're looking forward to a summer packed with adventures including logging a lot of experimental and analytical time, field work at Medicine Lake and Mt. Shasta volcanoes in Northern California with our MIT collaborators, participating and teaching the CIDER summer program at UC Berkeley, giving four presentations at IAVCEI 2017 in Portland, OR and much more.
Here are some pictures from recent adventures:
The EPIC lab was busy with great presentations and sessions at AGU this year!

EPIC post-doc Dr. Kayla Iacovino recently had her reserach on Mt. Paektu in N. Korea featured in a number of news outlets inclduing the New York Times, Nature Magazine and NPR. More about it here!
We spent an exciting three weeks in Japan this summer doing field work, visiting collaborators at Kanazawa University, attending the Goldschmidt Conference and exploring Mt. Fuji geology.
Supported and motivated by our NSF grant (EAR #1447342) to explore subduction zone mantle wedge processes in exhumed Japanese peridotites, EPIC PhD Student Meghan Guild and EPIC PI Christy Till traveled to Japan this summer for a host of activities. First and foremost was our successful (and rainy!) field work in the Higashi-Akaishi peridotite on the Japanese island of Shikoku, which built upon our sampling trip there last summer. After that we were off to visit collaborator Dr. Tomoyuki Mizukami at Kanazawa University on the North coast of Japan, where we had great discussions, sample exchanges, giving talks on our research and an amazing seafood dinner. Then off to Goldschmidt, where both Meghan and Christy gave talks, meet with scientists in our field, and last but not least went on a field trip to explore the recent eruptive history of Mt. Fuji with the experts. It was an incredible three weeks, here's a few photos that give you a taste of the fun!
