James “Jim” Powell was born in Berea, Kentucky, and earned his undergraduate degree in geology from Berea College. He holds a Ph.D. in Geochemistry from the Massachusetts Institute of Technology and has received honorary Doctor of Science degrees from Berea College and Oberlin College. He taught geology at Oberlin for more than 20 years and is a longtime Fellow of the Geological Society of America.
Dr. Powell has held numerous senior leadership roles across higher education and science institutions, including serving as President of Franklin & Marshall College, President of Reed College, President of The Franklin Institute, and President and Director of the Natural History Museum of Los Angeles County. He was appointed to the National Science Board by Presidents Ronald Reagan and George H. W. Bush and served for 12 years. Asteroid 9739 Powell was named in his honor.
In January 2022, Dr. Powell retired after 20 years as Executive Director of Graduate Fellowships for STEM Diversity, where he helped shape and strengthen the organization’s national impact in advancing opportunity in STEM.
He is the author of numerous books that explore science, history, and public understanding of science, including Faith in Fallacy: A Century of State-Sanctioned Science Denial (Oxford), Mysteries of the Deep: How Seafloor Drilling Expeditions Revolutionized Our Understanding of Earth History (MIT Press), Unlocking the Moon’s Secrets: From Galileo to Giant Impact (Oxford University Press), The 2084 Report: An Oral History of the Great Warming, and Deadly Voyager: The Ancient Comet Strike That Changed Earth and Human History.
Among the honors he values most are the naming of a geology laboratory in his honor at Oberlin College and his recognition as one of Berea College’s “100 Notable Bereans.” He credits Berea College, Oberlin College, and MIT with shaping his lifelong commitment to scientific excellence, education, and public engagement.

Dr. Kerri Blobaum
Kerri Blobaum is a materials scientist in the Materials Science Division at Lawrence Livermore National Laboratory. She received a B.A. in chemistry and mathematics from Wartburg College (Waverly, IA) in 1994, a M.S. in materials science from the University of Wisconsin-Madison in 1996, and a Ph.D. in materials science and engineering from Johns Hopkins University in 2001. As an undergraduate student, Kerri completed internships at Argonne National Laboratory and Pacific Northwest National Laboratory. Kerri first came to LLNL as a summer student in 1994, and then followed her LLNL mentor, Professor Tim Weihs, to JHU where she studied phase transformations and materials characterization of reactive multi-layer foils. Kerri returned to LLNL in 2001 as a postdoc and applied her skills to studying phase stability in plutonium-gallium alloys. As a staff member, Kerri contributed to work related to plutonium aging and led an internal research project on the kinetics of martensitic transformations in Pu-Ga alloys. Since that time, Kerri was involved in a variety of projects at LLNL, including leading the multi-disciplinary team that developed the infrastructure and techniques for fabricating special high-precision targets for high-energy-density experiments at the National Ignition Facility (NIF), serving as the scientific editor for LLNL’s publication “Science & Technology Review,” and building a plan and team to assess and certify manufacturing fluid compatibility for a new stockpile component. Prior to her current role on the National Nuclear Security Administration’s Defense Programs Science Council, Kerri was the LLNL program manager for the Aging and Lifetimes Program; she managed a portfolio of projects related to new and legacy materials in the nation’s nuclear stockpile, and diagnostic development for Core Surveillance. In the Materials Science Division at LLNL, Kerri was the Associate Division Leader for Materials for Program Enablement.
Kerri also serves on the Board of Regents at Wartburg College and the Board of Directors for the non-profit organization GFSD, which grants graduate fellowships in STEM fields. As an undergraduate, Kerri earned a GFSD fellowship, with LLNL as her sponsoring employer; she credits the experience she had as a GFSD summer intern at LLNL for launching her career.

Marinda Thomas
Marinda is a San Francisco native and a proud Graduate Fellowships for STEM Diversity alumni. After receiving a BS in Chemistry from Howard University, GFSD supported her in receiving a MS in Civil & Environmental Engineering from Stanford University. She started her professional career as an Environmental Engineer and designed water/wastewater infrastructure projects across California before realizing she liked people even more than pipelines.
Marinda has since been recruiting in Silicon Valley for over 10 years, initially specializing in software engineering, product and design searches. She then moved into a leadership recruiting function, first at a boutique agency and then in-house at Facebook. From there, she next launched her own successful recruiting business, helping a wide variety of startups identify both technical and non-technical talent of all levels. She is now the Sr Talent Acquisition Partner at Geli, a startup in the renewable energy storage space.
When she’s not working, Marinda is an avid snowboarder and loves camping (and glamping!) during the summer months. On her quest to be a polyglot, she speaks Spanish, decent German and horrible Italian.
