Carey Term Chairs in Mathematics:
Dr. Epstein and Dr. Ziller

Dr. Charles L. Epstein and Dr. Wolfgang Ziller have been appointed to Francis J. Carey Term Chairs in Mathematics, SAS Dean Samuel H. Preston recently announced.

Dr. Epstein received his S.B. from MIT in 1978 and his Ph.D. from NYU in 1983. Before coming to Penn in 1985, he was an instructor and National Science Foundation postdoctoral fellow in the mathematics department at Princeton University. He has held visiting positions at the Mathematics Institute in Göttingen, MIT, the I.H.E.S. in Bure sur Yvette, the University of Paris, the E.T.H. in Zurich, the Institut für Mathematik in Bern, and the Institute for Advanced Study in Princeton. He has been the recipient of several National Science Foundation grants and an Alfred P. Sloan Research Fellowship. His research and teaching interests include several complex variables, microlocal analysis, index theory, and medical image reconstruction.

Dr. Ziller received his B.A. and Ph.D. from the University of Bonn in 1971 and 1975, respectively. Before coming to Penn in 1979, he was an assistant at the University of Bonn, a lecturer at the University of California at Berkeley, and a member of the Institute for Advanced Study in Princeton. He has been a visitor at the I.H.E.S. in Paris, the Max Planck Institute in Bonn and Leipzig and the Institute for Advanced Study. Like Dr. Epstein, he has received several NSF grants and an Alfred P. Sloan Research Fellowship. He is a member of the American Mathematical Society and the Deutsche Mathematiker Vereinigung. His research interests are in the area of differential geometry, in particular, existence of closed geodesics, Einstein metrics, geometry of homogeneous and symmetric spaces, cohomogeneity one manifolds and metrics with nonnegative or positive sectional curvature.

The Francis J. Carey Term Chairs were created by William Polk Carey in honor of his brother Francis, who is president of the New York investment-banking firm of W. P. Carey & Co., Inc. Francis graduated from the College with a degree in mathematics in 1945 and from the Law School in 1949, while William graduated from Wharton in 1953. In addition to his generous financial support, William Carey provides valuable leadership in the Penn community, particularly as chair of the advisory board of the Institute for Economic Research.
