Deputy Director for Science and Technology (CRO)

Bonnie Fleming is Fermilab’s Deputy Director for Science and Technology and Chief Research Officer. An internationally recognized particle physicist with outstanding expertise and a world leader in neutrino physics, she leads all areas of science and technology at Fermilab.

Fleming began her career at Fermilab as a graduate student from Columbia University working on the NuTeV experiment and then as a Lederman Fellow working on MiniBooNE. She served as the founding spokesperson for the ArgoNeuT experiment and for the MicroBooNE experiment (later co-spokesperson). She has been a leading collaborator on SBND and DUNE and pioneered the detector technology employed for all these experiments, Liquid Argon Time Projection Chambers, which is also the technology employed by DUNE.

Formerly the Deputy Chief Research Officer at Fermilab from 2016 to 2018, Fleming has served on the 2014 P5 HEPAP subpanel, and more recently served as co-chair for the DOE Basic Research Needs on Instrumentation and the ongoing HEPAP subpanel on International Benchmarking. Currently, she serves as a member of the National Academies Decadal Survey in particle physics. She has received numerous honors and awards, including an APS Fellowship in 2013. Fleming earned a Ph.D. in physics from Columbia University.
