A theoretical particle physicist by training, he has also worked in experimental particle physics and cosmology. He is the author of two advanced textbooks and important results on the Higgs boson, dark energy, and how particle physics influences our everyday lives. He was an active member of Scientists for Sakharov, Orlov, and Shcharansky, which worked for the freedom of these victims of Soviet oppression.

Chris Quigg is Distinguished Scientist Emeritus at the Fermi National Accelerator Laboratory. He graduated in physics at Yale before moving to Berkeley for his doctorate. He is the author of an acclaimed text on gauge theories and critical works on high-energy collisions, quarks, neutrinos, and the Higgs boson.  He received the American Physical Society’s Sakurai Prize for theoretical physics and the German Alexander von Humboldt Prize. He rejuvenates himself on annual treks along France’s network of long-distance hiking trails.
