Mike Witherell

Mike Witherell is an American particle physicist and prominent scientific administrator known for his leadership of major national research facilities. He served as the director of the Fermi National Accelerator Laboratory (Fermilab) and later as the director of the Lawrence Berkeley National Laboratory. His career has been dedicated to advancing the frontiers of high-energy physics and managing large-scale scientific projects within the United States Department of Energy complex.

Early life and education

Mike Witherell was born on October 23, 1946, in San Diego, California. He pursued his undergraduate studies in physics at the University of California, Berkeley, earning a Bachelor of Science degree. He then continued his graduate education at the University of Wisconsin–Madison, where he completed his Ph.D. in physics. His doctoral research focused on experimental particle physics, laying the foundation for his future work at major accelerator laboratories.

Career and research

Following his Ph.D., Witherell began his professional career as a faculty member in the physics department at the University of California, Santa Barbara (UCSB). At UCSB, he conducted research in experimental particle physics, contributing to experiments that utilized particle accelerators to study fundamental forces and particles. His work often involved collaborations at national laboratories, including Fermilab and the Stanford Linear Accelerator Center (SLAC). He became a recognized figure in the field, investigating phenomena such as CP violation and the properties of charm and bottom quarks.

Leadership at Fermilab

In 1999, Mike Witherell was appointed director of Fermilab, one of the world's premier laboratories for particle physics research. During his tenure, he oversaw the conclusion of the Tevatron collider's flagship research program, which included the discovery of the top quark. He guided the laboratory's transition towards future projects, emphasizing the development of neutrino physics. Key initiatives advanced under his leadership included the planning for the Main Injector Neutrino Oscillation Search (MINOS) experiment and early development of the NuMI neutrino beam. His directorship focused on maintaining the laboratory's scientific vitality while navigating evolving priorities in the high-energy physics landscape.

Director of Lawrence Berkeley National Laboratory

Witherell became the director of the Lawrence Berkeley National Laboratory (Berkeley Lab) in 2016, succeeding Paul Alivisatos. As director, he leads a multidisciplinary research institution with programs spanning fundamental science, energy technology, and computational science. He has overseen major projects such as the upgrade of the Advanced Light Source, the development of the COSMIC facility at the SLAC National Accelerator Laboratory, and Berkeley Lab's significant role in the Deep Underground Neutrino Experiment (DUNE) based at Fermilab. His leadership emphasizes strengthening the laboratory's contributions to Department of Energy missions in science, energy, and environmental research.

Awards and honors

Throughout his career, Mike Witherell has received recognition for his scientific and leadership contributions. He was elected a Fellow of the American Physical Society for his experimental research in particle physics. His service has been acknowledged by institutions such as the University of California and the United States Department of Energy. He has served on numerous advisory committees, including those for the National Science Foundation and the High Energy Physics Advisory Panel (HEPAP), helping to shape the national strategy for physical sciences research.
