Sau Lan Wu


Sau Lan Wu is a Chinese American particle physicist and the Enrico Fermi Distinguished Professor of Physics at the University of Wisconsin-Madison. She made important contributions towards the discovery of the J/psi particle, which provided experimental evidence for the existence of the charm quark, and the gluon, the vector boson of the strong force in the Standard Model of physics. Recently, her team located at the European Organization for Nuclear Research, using data collected at the Large Hadron Collider, was part of the international effort in the discovery of a boson consistent with the Higgs boson.

Early years

Wu was born in Hong Kong and went to Vassar College in 1960 with a full scholarship for her undergraduate degree. Initially she dreamed of becoming a painter, but was inspired by Marie Curie to devote her life to physics. During her years in Vassar, she spent a summer at Brookhaven National Laboratory where the science of particle physics captivated her.
Reminiscence of her years in Vassar, Wu relished the experience and recollected her adjustment to the American society and culture as a difficult but positive one. During her freshman year she and other Vassar students were invited to the White House for an Easter function and met Jacqueline Kennedy, a Vassar alumna. She first experienced racial discrimination when visiting the Supreme Court and was confronted with the choice of "black" or "white" on the door to the restroom.

Academic background

Wu graduated from Vassar College with a B.A. in Physics. After earning an M.A. and a Ph.D. in Physics from Harvard University, she conducted research at MIT, DESY and the University of Wisconsin-Madison, where she is now the Enrico Fermi Distinguished Professor of Physics. Since 1986, Wu has been the Visiting Scientist at CERN conducting research with the LHC as part of the ATLAS team.

Achievements

J/psi

Wu was part of the team led by Samuel C.C. Ting at MIT who discovered the J/psi particle in 1974, for which Ting was awarded the 1976 Nobel Prize in Physics together with Burton Richter.

Gluon

Wu was a key contributor to the discovery of gluon. For her effort, Wu and her collaborators were awarded the 1995 European Physical Society High Energy and Particle Physics Prize.

Higgs boson

Wu is a group leader working on the ATLAS experiment, one of the two main detectors at CERN. Her team specializes in studying simulations of particle collisions that mimic the data that will be produced by the LHC based on current theories. On July 4, 2012, CERN announced the discovery of a boson consistent with the predicted characters of Higgs boson. This discovery completes the Standard Model of particle physics which explains the visible Universe. Wu is credited as a significant contributor to the discovery.

PhD Students

Wu has mentored more than 50 PhD students, which she counts as one of her major accomplishments.

Honors

Wu lives in Geneva and conducts research in CERN. She is married to Tai Tsun Wu of Harvard University.
