Young-Kee Kim, an experimental particle physicist, is the Louis Block Professor in Physics at the University of Chicago. She has devoted much of her research work to understanding the origin of mass for fundamental particles by studying the two most massive particles (the W boson and the top quark), and the Higgs particle that gives mass to elementary particles. Kim served as the leader of the CDF experiment at Fermilab’s Tevatron between 2004 and 2006, a premier particle physics experiment with more than 600 physicists from around the world. Between 2006 and 2013, she served as Deputy Director of Fermi National Accelerator Laboratory (Fermilab). Her primary roles were to develop a strategic plan for Fermilab and implement the plan, to play a role of the Chief Research Officer, the highest executive position in research, and to play an acting Director role when the Director is absent. Kim has served on numerous national and international advisory committees, councils and boards.
