Stephen Della Pietra

Stephen Della Pietra

Stephen Della Pietra received his bachelor’s degree in physics from Princeton University in 1981, and his PhD in mathematical physics from Harvard University in 1986. From 1987 to 1988, he was a postdoctoral fellow at The University of Texas at Austin. From 1988 to 1989, he was a member at the Institute for Advanced Study in Princeton.

From 1989 to 1995, he was a research staff member at the IBM Thomas J. Watson Research Center in Yorktown Heights and Hawthorne, New York. As a project leader of the natural language understanding group, his primary research focused on machine translation and natural language understanding. In 1995 he joined Renaissance Technologies, where he currently co-manages the General Research Group and works on statistical methods to model the stock market.

Stephen is co-founder of the Della Pietra Lecture Series at Stony Brook University. This series brings world-renowned scientists to the Simons Center for Geometry and Physics, and is intended to bring awareness of recent and impactful discoveries in physics and mathematics to high school, undergraduate and graduate students. Stephen is a board member of the Simons Center for Geometry and Physics, is on the advisory council of the astrophysics department at Princeton University, as treasurer of the National Museum of Mathematics in New York, and is a board member of the nonprofit organization PIVOT.

Marie A. Vitulli

Dr. Marie A. Vitulli is an American mathematician whose research areas are commutative algebra and applications to algebraic geometry. Vitulli heads the Women in Math Project at the University of Oregon. She has established the Marie A. Vitulli Fellowship through a generous endowment gift to MSRI to support and foster young mathematical talents.

Vitulli was an undergraduate at the University of Rochester and earned her Ph.D. in 1976 at the University of Pennsylvania. Her research topics have included deformations of monomial curves, seminormal rings, the weak normality of commutative rings and algebraic varieties, weak subintegrality, and the theory of valuations for commutative rings.

With Mary Flahive, Vitulli has also studied patterns in hiring among women mathematicians. She is part of the 2019 class of fellows of the Association for Women in Mathematics, and was elected as a Fellow of the American Mathematical Society in the 2020 Class. Women in mathematics are of particular interest to Vitulli, and this fellowship aims to support women graduate students in this important field.
