David B. Kaplan

David B. Kaplan is an American physicist born in 1958. He was Director of the Institute for Nuclear Theory at the University of Washington during the period 2006-2016 and is now a Senior Fellow there.

Kaplan's research deals with various aspects of quantum field theory, applied to models of physics beyond the Standard Model, cosmology, nuclear physics, and lattice QCD. He is known for his work on the theory of the composite Higgs boson, the role of the strange quark in dense matter and the phenomenon of kaon condensation, development of the theory of electroweak baryogenesis and other aspects of particle astrophysics, for lattice models with exact supersymmetry, and for the formulation of lattice gauge theory with chiral fermions. The latter is known as the theory of domain wall fermions, and is an early example of what has become known among condensed matter physicists as a topological insulator.

Kaplan is a Member of the National Academy of Sciences, the American Academy of Arts and Sciences, and the Washington State Academy of Sciences, and is a Fellow of the American Physical Society. He is a recipient of the Department of Energy Outstanding Junior Investigator award, the National Science Foundation Presidential Young Investigator Award, and an Alfred P. Sloan Foundation fellowship.
