It is a pleasure to welcome the new members of the School
of Mathematics - Professors Douglas Arnold and Carme Calderer who are
husband and wife, Professor Andrew Odlyzko, Professor Peter Polacik, Associate
Professors Arnd Scheel and Alexander Voronov,
and Assistant Professors Wojciech Chacholski and Markus Keel. Professor
Arnold is also the new director of the Institute for Mathematics and its
Applications (IMA), replacing the outgoing director, Professor Willard
Miller, who decided to return to teaching and research. Professor Odlyzko
is the first director of the newly established Digital Technology Center
(DTC) and an assistant vice president for research. We also welcome the
new Dunham Jackson Assistant Professors Bernard Badzioch, Junho Lee and
Jianfeng Zhang, as well as Postdoctoral Associates Reka Albert, Chetan
Gadgil and Maria Gracheva.
Professor Arnold, the new IMA Director, is one of the
world's leaders in numerical analysis of partial differential equations,
particularly those dealing with mechanics.
He has made major contributions to the numerical simulation of elastic
plates and shells and also of incompressible fluids. In recent years he
has been working in the area of computational relativity, which seeks
numerical solutions of Einstein's field equations. Douglas Arnold earned
his Ph.D. in 1979 from the University of Chicago. His first position was
at the University of Maryland. In 1989 he joined the faculty of Penn State
University as Professor and was made Distinguished Professor in 1995.
At Penn State he was also co-director of the Center for Computational
Mathematics and Applications, the associate director of the Institute
for High Performance Computing Applications, and a member of the Center
for Gravitational Physics and Geometry. His major honors and recognitions
include the first Giovanni Sacchi Landriani Prize of the Milan Academy
of Arts and Letters and an invitation to give a Plenary Lecture at the
International Congress of Mathematicians in Beijing in August 2002. For
more about Professor Arnold, see the article about
the IMA. .
Professor Maria-Carme Calderer is a well known applied
mathematician whose research interests include mathematical studies of
liquid crystals. She earned her doctorate from Heriot-Watt University,
Edinburgh, in 1980. She has been at Penn State since 1989 where she was
promoted to the rank of Professor in 1993. She was a postdoctoral researcher
at the IMA (1984-1985) as well as a visiting researcher in 1986-1987 and
1995-1996. She also has an active interest in mathematics education at
both the undergraduate and graduate levels, as well as K-12 education.
Professor Peter Polacik has made important contributions
in the areas of partial differential equations and dynamical systems.
He earned his doctorate from Comenius University, Bratislava, in 1989,
where he rose to the rank of Professor. He has been a frequent visiting
researcher to leading institutions throughout the world, including the
IMA (Fall 1989) and Newton Institute for Mathematical Sciences (Fall 1995).
Andrew Odlyzko is a mathematician of world renown whose research interests
cover large areas of pure and applied mathematics and computer science,
including number heory, combinatorics, analysis, probability theory, computational
complexity, cryptography, coding theory, electronic publishing, electronic
commerce and economics of data networks. In addition to his position on
the mathematics faculty, Professor Odlyzko is the first director of the
University's new Digital Technology Center (DTC), Assistant Vice President
for Research, and ADC Telecommunications Chair Professor. For more details
about the DTC see www.dtc.umn.edu
as well as our article on the DTC.
Andrew Odlyzko earned his Ph.D. from MIT in 1975 and joined
AT&T Bell Laboratories, now AT&T Labs, where he held high level positions
for nearly two decades, most recently, since 1996, as head of the mathematics
and cryptography research department. His major honors include an invited
one-hour address at the annual AMS meeting, Pittsburgh 1981, as well as
an invited lecture at the International Congress of Mathematicians, Berkeley
1986. He also serves on the editorial boards of many
leading mathematics, computing, communications, and digital technology
journals and has been a member of advisory or governing boards for leading
educational institutions throughout the country, including the IMA.
Associate Professor Arnd Scheel's research is in the area
of dynamics of partial differential equations. He earned his doctorate
from the University of Stuttgart in 1994 and joined the faculty of the
Free University, Berlin. He is the recipient of the Outstanding Paper
Prize of the Society for Industrial and Applied Mathematics for the year
Associate Professor Alexander Voronov's
research interests lie in mathematical physics, algebra, algebraic geometry
and topology. He earned his Ph.D. from Moscow State University in 1988,
where he held a research position until 1990. In the US he has had faculty
positions at MIT, University of Pennsylvania and Princeton University,
among others. He was a visiting researcher at Max-Planck Institute, Institute
for Advanced Study and IHES, and was awarded an AMS Centennial Research
Fellowship, 1996-1998. He earned a Good Teaching Award from the University
of Pennsylvania in 1995.
Assistant Professor Wojciech Chacholski earned his Ph.D.
in 1995 from the University of Notre Dame. His field of research is algebraic
topology. From 1995 to 1997 he held a J.E. Marsden Postdoctoral Fellowship
at the Fields Institute (Toronto), followed by a G. Faltings Postdoctoral
Fellowship at Max-Planck Institute (1997-1998). From 1998 to
2001 he was a Gibbs Instructor at Yale University, taking a one-year leave
of absence (1999-2000) to hold a Gustafsson Fellowship at the Royal Institute
of Technology (Stockholm). He is spending the current academic year there
as well, on leave from our department.
