James A. Isenberg

James A. Isenberg is an American theoretical physicist.

James A. Isenberg

Career

He is one of the pioneers in the study of the constraint equations in classical general relativity. His many important contributions include the completion of the solution theory of the constraint equations on closed manifolds with constant mean curvature, and with his collaborators, the first nontrivial results on the non-constant mean curvature case.

He was a graduate student under Charles Misner at the University of Maryland in the seventies.[1] He is a professor of mathematics and physics at the University of Oregon.

Isenberg lives in Philadelphia, Pennsylvania, with his wife, economist Pauline Kennedy.

Recognition

He was named to the 2021 class of fellows of the American Mathematical Society "for contributions to mathematical general relativity and geometry flows".[2]
