  • The current and past recipients of the Harriet Benson Award gathered for the Annual Harriet Benson Fellowship Luncheon on Thursday, August 15, 2024, at the Stanford Faculty Club. This event provided an opportunity for awardees to share their ongoing research and projects, fostering a community of scholars committed to excellence in Earth and Planetary Sciences.

    The Harriet Benson Award recognizes exceptional scholarship and research accomplishments by graduate students in the Department of Earth and Planetary Sciences. We are thrilled to congratulate PhD student Emily Ellefson on being awarded the AY 2023-2024 Harriet Benson Fellowship. This prestigious award honors a continuing graduate student in their advanced years of study and celebrates their contributions to the field.
    This award is made possible by the generous endowment gift from Dr. Harriet Benson, a retired chemist with a long history of supporting Stanford and its students, particularly the women’s basketball team. Dr. Benson’s interest in Earth sciences has led her to audit several EPS courses over the past few years. Her gift is intended to further the careers of talented young scientists.

    While some past recipients were unable to attend the luncheon, they eagerly shared updates on their careers and research:

  • The science of scenery

    Despite its ups and downs, Willenbring credits the 20-acre farm in North Dakota west of Mandan where she grew up with offering a combination of factors that eventually led her to pursue geology research: soils that govern sustenance, abundant time for exploring the outdoors, proximity to a unique landscape where the Great Plains give way to the rugged Badlands, and a yearning to distinguish herself in order to leave that difficult life in the Midwest.

  • The Doerr School of Sustainability hosted a launch symposium this summer for Mineral-X, a new affiliate program that combines technological innovation with community representation and stewardship with the ultimate goal of a resilient mineral supply chain to achieve clean renewable energy.

  • We think we know how mountains form. Plate tectonics causes rock to be pushed up at fault boundaries. Except that model is hard to prove, and a new study suggests it might actually be a lot more complicated. Video is based on the work done by Dr. Nikki M. Seymour, during her time as a EPS postdoc.
