JoAnne Hewett - Chief Research Officer
JoAnne is a world-class theoretical physicist with well over 100 publications in theoretical high energy physics. Her research probes the fundamental nature of space, matter and energy, where she most enjoys devising experimental tests for preposterous theoretical ideas. She is best known for her work on the possible existence of extra spatial dimensions. She has twice been a member of the HEPAP advisory panel and made major contribution to the recent Particle Physics Project Prioritization Panel (“P5”) plan, which defines U.S. high-energy physics research priorities for the next 10 years.
Since joining the SLAC faculty in 1994, JoAnne has served in key leadership roles here at SLAC, including head of the theoretical physics group, Deputy Director of the Science Directorate and Director of SLAC’s Elementary Particle Physics (EPP) Division. During her tenure as EPP Division director, JoAnne aligned the program with the highest P5 priorities by establishing a neutrino theory program and extending SLAC’s experimental efforts work in accelerator-based neutrino physics and neutrinoless double-beta decay. She was elected a fellow of the American Physical Society in 2008 and named a fellow of the American Association for the Advancement of Science in 2009, and served as chair of the American Physical Society’s Division of Particles & Fields in 2016.
