Dr. Feldman, Department of Mathematics, The University of British Columbia, has made many deep and significant contributions to mathematical quantum field theory; for example, the construction and analysis of the [phi]4/3 model, sharp bounds on general Feynman graphs, and analysis of singularities in the complex Borel plane for [phi]4 theories, and a proof of renormalizability of QED4. With Magnen, Rivasseau and Sénéor, he constructed the (non-superrenormalizable) infrared [phi]4/4 and Gross-Neveu_ models, by developing powerful new techniques (phase space expansions) theories. He has become one of the world's leading field theorists.
