I'm originally from Oregon, and did my undergrad at Oregon State University.
I worked at the USGS for more than a year for the Earthquake Hazards
Group in Menlo Park. I am currently starting my 3rd year of research
at Stanford. My general research interests include volcanology, igneous
petrology, and Tectonics. My PhD. research is trying to investigate
if 16.5-15 Ma voluminous peralkaline silicic magmatism, exposed across
in northwest Nevada and southern Oregon, is related to the impingement
of a Yellowstone Plume. I am doing regional scale mapping, locating
caldera sources throughout the area, argon and paleomag geochronology
to establish the geologic evidence for voluminous silicic magmatism
in the area. I will also be using geochemistry, Sr and Nd isotopic analyses,
and Ti-in-Quartz geothermometry to better understand the petrogenesis
of these peralkaline magmas and through what processes they have evolved.
Out of my office, I enjoy road and mountain biking, skiing, rock climbing,
hiking movies, and making beer (and drinking it). Also, I enjoy cooking,
photography, and traveling.
Gwyneth is originally from Baltimore, MD and attended Oberlin College
where she double majored in mathematics and geology. During this time
she completed an honors project on developing mathematical representations
of folded surfaces with Steve Wojtal, and had the opportunity to do
experimental petrology research at the Lamont-Doherty Earth Observatory
with Prof. Dave Walker. After graduating, she taught mathematics at
Dunbar High School in Washington D.C. for two years through the Teach
for America Program. She is currently in her fifth year of the GES
PhD program at Stanford and is additionally pursuing an MS in Geophysics.
Gwyn's main advisor is Prof. Gail Mahood, but she also works with
Prof. Paul Segall.
Areas of Interests:
Physical volcanology, mathematical modeling, structural geology, and
Gwyn is primarily interested in studying how magma and crust interact
in volcanic systems. Current projects include (1) determining how continental
crustal properties influence the formation of large silicic calderas
by examining calderas worldwide and (2) utilizing deformation and seismicity to
develop a model for magmatic intrusion during the 2000 Miyakejmia event. In addition, Gwyn spent
two summers doing GPS work in Kamchatka with the PIRE project, studying Bezymianny volcano.
