Michael Stewart Witherell (born 22 September 1949) is an American particle physicist and laboratory director.^[1] He has been the director of the Lawrence Berkeley National Laboratory since 2016.^[2][3] Witherell, a particle physicist, previously served as Director of Fermilab. He previously served as professor and vice chancellor for research at the University of California, Santa Barbara.

Early life and education

He was born 22 September 1949 in Toledo, Ohio.^[1] Witherell received a Bachelor of Science from the University of Michigan in 1968 and a Doctor of Philosophy from the University of Wisconsin, Madison in 1973.^[1][3]

Career

From 1973 to 1981 he was on the faculty of Princeton University. He was a member of the physics faculty at the University of California, Santa Barbara from 1981 to 1999.^[1]

In 1985 Witherell led an experiment at Fermilab which was the first to isolate a large sample of particles containing the charm quark using the new technology of silicon microstrip detectors.^[4] He received the 1990 Panofsky Prize from the American Physical Society for this research. In 1998 he was elected to the National Academy of Sciences.

Witherell served as the Director of the Fermilab from 1999 to 2005. In 2005 he returned to UC Santa Barbara as the Vice Chancellor for Research, serving in that role until 2016.^[1]

In January 2016, the University of California Board of Regents appointed him to be the Director of Lawrence Berkeley National Laboratory.^[2] In 2017 he was elected to the American Academy of Arts and Sciences.^[5]

Service

Witherell chaired the Fermilab Program Advisory Committee from 1987 to 1989 and the SLAC Scientific Policy Committee from 1994 to 1996, and the High Energy Physics Advisory Panel of the United States Department of Energy from 1997 to 1999.^[1] He chaired the Mathematical and Physical Sciences Advisory Committee (MPSAC) of the NSF from 2006 to 2008 and the National Academy of Science's Board on Physics and Astronomy from 2015 to 2016.

Witherell served on the National Academies' Committee on Science, Engineering, Medicine and Public Policy (COSEMPUP) from 2017-2021. He was elected to the National Academy of Sciences Council in 2023.^[6]
