A Lifelong Mentor
Distinguished Professor Emeritus Ralph Archuleta establishes endowed fellowship fund in geophysics
As Professor Emeritus Ralph Archuleta watched students step up to receive prizes, scholarships, and fellowships at a Department of Earth Science awards ceremony years ago, he noticed that few recognized those in his field of geophysics. Ever the mentor, Ralph saw an opportunity for support. His legacy gift to the Department of Earth Science will endow the Archuleta Family Fellowship in Earth Science to recognize graduate students in geophysics.
“I wanted to ensure that the award would help motivate graduate students, because I think they are the engine that drives most departments. You have good faculty members, but if you get good graduate students, that is rejuvenation,” said Ralph.
Ralph mentored 17 graduate students during his 30-year career at UC Santa Barbara. He delighted in helping them pursue 17 different research questions tailored to their strengths.
“With graduate students, there was never a lack of work to be done, or a lack of excitement, and people pulled together. We collaborated, but the graduate students followed their own ideas,” he said.
Most seismologists study the structure of the Earth. Ralph focused on understanding an earthquake’s source to predict ground motion and improve engineering design. He studied physics at the University of Wyoming before moving to UC San Diego, where he completed an M.S. in physics and a Ph.D. in earth sciences through the Institute of Geophysics and Planetary Physics at Scripps Institution of Oceanography.
After his Ph.D., he began his career at the U.S. Geological Survey in Menlo Park, CA. Ralph published an influential paper that led to opportunities to travel and deliver presentations. In 1984, he and his late wife, Lucy, moved to Santa Barbara to join UCSB. Lucy got a job as an accountant and soon made partner at a local firm. It was she who encouraged Ralph to create a legacy with the Department of Earth Science.
“Because of her work, and with my salary at the university, we could bank some extra money. I never in my whole life would have expected this. I grew up in a coal mining camp in Reliance, Wyoming, which has 300 people if you count cats and dogs. My dad was a coal miner until he lost his job when the mines closed, and my mother cleaned houses in nearby Rock Springs. The idea that we could give something back to students is not something I ever even dreamed about, but I’m happy to do it,” said Ralph.
“Ralph is a longtime member of our faculty and has contributed to the department in many ways, including as an accomplished researcher, graduate student mentor, teacher, and administrator. He was the chair when I was hired. Even after his retirement, he has continued to be an important part of our community, providing a fellowship for our geophysics graduate students and continuing to be engaged in research. We’ve all enjoyed his friendship and mentorship, and his gift will ensure his legacy in our department for years to come by supporting our graduate program in geophysics,” said Department Chair Alexander Simms.
“It makes a big difference when you see your students doing this wonderful work. You’re just so happy for them and proud of what they’re doing. They can sense it, too. They recognize that what they’re doing is important and that it makes a difference in the scientific world,” said Ralph. “I want to encourage the cadre of students in geophysics, particularly seismology. That was the motivation, and it was decided quite a long time ago.”
