Professor Gottlieb is one of the world's foremost authorities on quantum chromodynamics (QCD) -- the theory of the strong interaction -- and, in particular, lattice QCD, in which space and time are broken up into a grid and computers perform complex calculations at each grid point.
Like the strong interaction, Gottlieb has served as a binding force in the lattice QCD community. He co-founded the MILC collaboration -- one of the world's leading lattice gauge theory research groups -- and has generously shared his ideas, expertise and computer code with scientists and research groups worldwide.
Gottlieb is one of the principal authors of the MILC code for lattice gauge theory calculations and a sought-after advisor on supercomputing. He chaired the Oversight Committee of the National Lattice Gauge Theory Infrastructure Project from 2001 to 2006, and he is a member of the Change Control Board for the U.S. Department of Energy's Lattice QCD Computing Project.
An American Physical Society Fellow, Gottlieb has co-authored more than 215 publications, and he received the IU Outstanding Young Faculty Award in 1989. Gottlieb has held visiting positions at the Massachusetts Institute of Technology and Brookhaven National Laboratory, and he was a Frontier Fellow at the Fermi National Accelerator Laboratory. He has served two terms as divisional associate editor for Physical Review Letters, and he is currently an editorial board member and associate editor in chief of Computers in Science and Engineering.
He received his Ph.D. from Princeton in 1978.
Gottlieb received the IU Bicentennial Medal in September 2020 in recognition of his distinguished contributions to Indiana University.
