"For developing concepts and techniques in QCD, such as infrared safety and factorization in hard processes, which permitted precise quantitative predictions and experimental tests, and thereby helped to establish QCD as the theory of the strong interactions."
Mueller received a BS degree from Iowa State University in 1961 and a PhD in Physics from MIT in 1965. The years 1965-1971 were spent at Brookhaven National Laboratory, and has been at Columbia since 1972. In addition, Mueller has enjoyed his leaves of a semester or more at New York University, the Institute for Advanced Study, the Institute for Theoretical Physics (Santa Barbara), SLAC, Saclay and Orsay. He has been awarded an A.P. Sloan Fellowship (1972), a J.S. Guggenheim Fellowship (1988) and a Citation of Merit from Iowa State University (1990). He is a Fellow of the American Physical Society, and is currently serving on visiting committees at the MIT Laboratory for Nuclear Science, the Werner Heisenberg Institute, and at Saclay (DAPNIA) as well as on the Science and Technology Steering Committee of Brookhaven Science Associates.
In the past Mueller has worked on the theory and phenomenology of high-energy hadronic reactions, on the short distance behavior of QCD, on properties of the large order perturbative series in QCD and on testing and understanding QCD using hard reactions in hadrons and nuclei. His current research focuses on high field strength and high-density QCD systems which can be studied in high energy hadronic and heavy ion reactions.
