Prior to joining Citigroup in the fall of 1999, Lewis had a long career at the Board of Governors of the Federal Reserve System, where he served most recently as the Deputy Director of the Division of International Finance. As Deputy Director, Lewis directed the Federal Reserve Board's analysis of foreign financial markets and international banking, represented the Federal Reserve in key international forums, and worked closely with the U.S. Treasury on the policy response to the crises in Asia, Latin America and Russia. Lewis also was an Associate Economist of the Federal Open Market Committee. Earlier, he served as Chief Economist of the U.S. Department of Commerce (1993-96) and was a consultant to the Bank for International Settlements (1988-89.) 

Lewis received his Ph.D. in Economics from Yale University in 1987, after obtaining an M.Phil. there in 1985. Previously, he obtained an A.M. (1979) and an A.B. (1978) in Economics from Stanford University.

NELSON, Edward

Edward NelsonEdward Nelson was born on May 4, 1932, in Decatur, Georgia. He is a professor in the Mathematics Department at Princeton University. He is known for his work on mathematical physics and mathematical logic. In mathematical logic, he is noted especially for his internal set theory. Nelson received his Ph.D. in 1955 from the University of Chicago, where he worked with Irving Segal. He was a member of the Institute for Advanced Study from 1956–1959. He has held a position at Princeton University from 1959 to the present, attaining the rank of professor there in 1964.

Nelson has made contributions to the theory of infinite dimensional group representations, the mathematical treatment of quantum field theory, the use of stochastic processes in quantum mechanics, and the reformulation of probability theory in terms of non-standard analysis.

For many years he worked on mathematical physics and probability theory, and still has a residual interest in these fields, particularly in possible extensions of stochastic mechanics to field theory.

In recent years he has been working on mathematical logic and the foundations of mathematics. One of his goals is to extend IST (Internal Set Theory—a version of a portion of Abraham Robinson's nonstandard analysis) in a natural way to include external functions and sets, in a way that provides an external function with specified properties unless there is a finitary obstacle to its existence. Other work centers on fragments of arithmetic, studying the divide between those theories interpretable in Raphael Robinson's Arithmetic and those that are not; computational complexity, including the problem of whether P is equal to NP or not; and automated proof checking.
