Lewis received a Fulbright Student Grant to study tectonic processes in the Pyrenees at the Universidad de Barcelona in 1994-1995. The current project is an extension of that earlier project, addressing fundamental questions about how mountainous topography evolves following plate-tectonic, continental collisions, and how river systems respond to post-tectonic processes.
"The Spanish Pyrenees and the adjacent Ebro Basin comprise an outstanding locality for isolating processes that drive rock-uplift in mountain ranges created by plate tectonic collisions, but where active compression and crustal thickening have ceased," Lewis said. "The results of this project will form a foundation for many future studies of landscape evolution, soil forming processes, archaeology, and impacts of tectonics and climate change on the continents. The results will also be applicable to questions of landscape stability and potential contaminant transport at existing and proposed hazardous waste repositories, both in Spain and in the United States."
Lewis, who received her doctorate in Geology from Harvard University, joined the Laboratory as a postdoctoral fellow in 1996. In addition to her ongoing work in Spain, she participates in the Laboratory's Seismic Hazards Program and various 3D geological modeling efforts near to home (the Española Basin) and far away (the Tibetan plateau.) She also serves on the Laboratory's Women's Diversity Working Group and served this past year on the Fellows Selection Committee.
A strong proponent of women in science, Lewis herself was discouraged by inadequate high school science and math from pursuing a major in Geology as an undergraduate. She opted instead for American Studies.
"It wasn't until after college, when I was working at a small, independent wood energy research lab in Santa Fe that I discovered I could do science," she said. "I took evening courses in college Algebra, Calculus, Physical Geology and Chemistry at Santa Fe Community College and UNM/Los Alamos. After that, I knew I was ready to get the geology degree I always wanted."
Lewis, who is fluent in Spanish, will spend two months next spring and again in 2002 doing research at the Universidad de Zaragoza as a Fulbright Senior Scholar.
Los Alamos National Laboratory, a multidisciplinary research institution engaged in strategic science on behalf of national security, is operated by Los Alamos National Security, LLC, a team composed of Bechtel National, the University of California, The Babcock & Wilcox Company, and Washington Group International for the Department of Energy's National Nuclear Security Administration.
Los Alamos enhances national security by ensuring the safety and reliability of the U.S. nuclear stockpile, developing technologies to reduce threats from weapons of mass destruction, and solving problems related to energy, environment, infrastructure, health, and global security concerns.
