Michael A. Revelli

Michael A. Revelli died Jan. 30, 2026. He was 76.

Revelli was born on Oct. 24, 1949, in Oakland, California, to Charles Edward Revelli and Shirley Addie (Archambault) Revelli. He grew up in the Oakland hills and graduated from Skyline High School in 1967. He went on to pursue his passion for science, studying physical chemistry at the University of California, Berkeley, where he earned his bachelor of science degree in 1971. He continued his academic journey at the University of California, Santa Barbara, receiving his doctor of philosophy in chemistry with a focus on laser spectroscopy in 1976. After completing his doctorate, he accepted a postdoctoral position in the chemistry department at Lawrence Livermore National Laboratory (LLNL) and moved to Livermore. His career included several years working on the Yucca Mountain Project in Nevada, followed by working in the Environmental Department’s Waste Management Program. He retired in 2017. Even after retirement, he continued his involvement with LLNL through the Public Affairs Science Outreach Program. In this role, he found great joy in sharing his love of science with elementary school students at LLNL’s Discovery Center, inspiring curiosity and wonder in young minds.
