André Walker-Loud is a Staff Scientist at Lawrence Berkeley National Laboratory (LBNL). He received his Ph.D. from the University of Washington, Seattle. He then held postdoctoral research positions at the University of Maryland, The College of William & Mary (W&M), and LBNL followed by a joint appointment as an Assistant Professor of Physics at W&M and as a Senior Staff Scientist at Thomas Jefferson National Accelerator Facility. In his research, he uses lattice QCD and effective field theory to gain a quantitative understanding of how nuclear physics emerges from QCD. He is also interested in probing the limits of the standard model by testing fundamental symmetries in nuclear environments.

Viewpoint: Dissecting the Mass of the Proton

A calculation determines four distinct contributions to the proton mass, more than 90% of which arises entirely from the dynamics of quarks and gluons. Read More »
