Abstract:

I am deeply honored to receive the MGPV Distinguished Geological Career Award. Without Wes Hildreth, I would not have found you, my marvellous geology family. His intro geology lab was mapping in the Berkeley Hills. What an epiphany! I have since based my science in field work, incorporated field trips in my classes, started international trips for GeoClub, and spearheaded an experiential learning-based K-5 charter school. Querying the Earth face to face, is empowering and humbling.

I cut my analytical teeth in the Berkeley Argon lab as a hired hand. Field assisting Gail Mahood in Sierra La Primavera, Mexico and Wes Hildreth at Katmai whetted my appetite for ignimbrites. Mapping and analyzing the heck out of the Calabozos Caldera and Loma Seca Tuff in Chile I learned, among many things, that compositional and thermal zonation in silicic magma chambers signals high thermal gradients imposed by roof-ward cooling enhanced by hydrothermal alteration and mafic underplating. It was a heady time at Stanford under the aegis of the first women tenure-track faculty in Geology, Gail Mahood and Elizabeth Miller and a fabulous group of graduate colleagues working and playing hard. I got the PhD and the Mrs as John Dilles was part of this mix and he has been a stalwart supporter of my science and our family ever since. When John and I joined OSU, I was the first tenure track woman in 100 years of the Geology. A senior colleague told me that my job was to shut up and that he had the right to hog storage space because he had an NSF grant. Well, so did I, thank you NSF. My career would not have been possible without steady NSF support, as it primarily funded students. I have had fantastic students; dedicated and lively. Our work spans basalt to rhyolite volcanism related to extension in Nevada and eastern Oregon, to subduction in the Cascades and Andes, and to the Yellowstone hot spot. My joy is to use petrology to constrain changing roles of magmatic processes during a magmatic period. To my students, coauthors, collaborators, mentors, colleagues and nominators and of course to my friends and family I give deepest thanks. I wouldn’t be standing here without you.
