Letter from the Department Chair

It is a pleasure to write to you with greetings and good news about the Department of Mathematics. I was appointed as the new department chair on August 16. We have been slated for advancement and investment by the College of Liberal Arts and Sciences. Our new support will help us to attract talented faculty and to pursue excellence in all aspects of our mission. We will be vigorously pursuing strong faculty appointments at both the senior and junior levels. We are also implementing plans to give our faculty more dedicated research time. We are improving our instruction and course offerings, and would like to increase student scholarships and fellowships. Our facilities, including historic Altgeld Hall, are targeted for renovation. It is an exciting time for our department!

I took over as chair from Joseph Rosenblatt, who selflessly served as Interim Chair. I'd like to take this opportunity to thank him for his service. Being chair is a busy job, but it's been made easier for me by Joe's assistance with the transition. Former chair Daniel Grayson has also been an immense help to me, as have numerous other members of the faculty and staff. Thanks to all!

We have hired many new personnel this fall and I'd like to introduce them here. Sergiy Merenkov is a new Assistant Professor who comes to us from a postdoctoral position at Michigan. He specializes in the geometric theory of conformal and quasiconformal maps and is particularly interested in applications to geometric group theory and analysis on fractals. We have also hired two new postdocs. Tao Mei received his Ph.D. in 2006 from Texas A&M and works in functional analysis and harmonic analysis. Julien Melleray received his Ph.D. in 2005 from the University of Paris 6 and works on logic, functional analysis, and their interactions. Read more about these faculty on page 3.

We also have many new visiting faculty:

  • Andrea Barreiro (Ph.D. New York University 2006)
  • Ilgiz Kayumov (Ph.D. Kazan State University 1997, Assistant Professor, Faculty of Mech. and Math., Kazan State University)
  • Maria Sabitova (Ph.D. University of Pennsylvania 2005)
  • Sonja Stimac (Ph.D. University of Zagreb 2002, TA with Ph.D. on tenure track licensed to lecture with Graduate School of Economics and Business, University of Zagreb)
  • Zoran Vondracek (Ph.D. University of Florida 1990, Professor at the Department of Mathematics, University of Zagreb).

In addition, Jing Li (Ph.D. University of California at Berkeley) has joined us as a new lecturer and Sue Purkayastha (M.Ed. in Math Education, University of Illinois) has arrived as a new instructor.

One of the more pleasant duties a department chair has is to advocate for and brag about the department. This is easy to do because of the many accomplishments of our faculty and students:

  • Slawomir Solecki and Richard Sowers have been promoted to Full Professor, and Dirk Hundertmark, Ilya Kapovich, Rinat Kedem, and Charles Rezk have been promoted to Associate Professor with tenure.
  • 66% of our faculty are Principal Investigators on external grants. This is our largest percentage in recent decades.
  • Twenty faculty have received new NSF grants in the last year.
  • Associate Professor Robert Ghrist received a $7.98 million grant from DARPA for his research program entitled SToMP: Sensor Topology for Minimal Planning, the largest grant ever received by a member of our department.
  • Our graduate students are engaging in research activities earlier through our REGS program (Research Experiences for Graduate Students) and our popular mini-courses. Eighteen students received Ph.D.’s last year and have been employed well.
  • We have 798 undergraduate majors enrolled in our combined undergraduate degree programs. Our largest specialized major is Actuarial Science in which 275 students are enrolled.

The strength of our department originates in its people, and I have enjoyed getting better acquainted with faculty, staff, and students. I have had the pleasure of discussing departmental history with retired faculty and look forward to meeting more of our alumni, an important group of our stakeholders.

Whether you are on campus or reflecting back on your time at the Department of Mathematics at UIUC, I wish you a productive Fall semester as we work together to keep improving our department.

Sincerely,

Sheldon Katz
Chair, Department of Mathematics

Meet the Faculty and Staff

Sergiy Merenkov
Assistant Professor
Ph.D. 2003, Purdue University
Sergiy Merenkov came to the United States from the Ukraine in 1999 as a graduate student in Mathematics at Purdue University. He received his Ph.D. from there in 2003 under the direction of Alexandre Eremenko. After that Merenkov held a three-year postdoctoral position at the University of Michigan, where he mainly worked with Mario Bonk. His research is on geometric theory of conformal and quasiconformal maps with applications to areas such as geometric group theory and analysis on fractals. In his spare time Professor Merenkov likes reading, both literature and news, listening to NPR, and exercising, such as weight lifting.
Tao Mei
J.L. Doob Research Assistant Professor
Ph.D. 2006, Texas A & M
Tao Mei, a native of China, received his Ph.D. from Texas A&M under the supervision of Dr. Gilles Pisier in 2006. Before he came to the U.S. in 2003, he spent one year in Besancon, France as a visiting scholar. His current research area concerns both functional analysis and harmonic analysis, especially in generalizations of classical results from harmonic analysis to operator valued (matrix valued) functions and related subjects, such as noncommutative martingales. He was married this past August. Mei enjoys playing tennis and badminton, and he likes playing "Go" very much.
Julien Melleray
J.L. Doob Research Assistant Professor
Ph.D. 2005, University of Paris
Julien Melleray received his Ph.D. from the University of Paris in December 2005. His research interests are descriptive set theory, logic, functional analysis and their interactions. In the past few years, Melleray has mostly concerned himself with the study of the Urysohn universal space, a fascinating object that seemingly is at the "border" of these domains; its history is also fascinating, since it is the last mathematical work of Pavel Urysohn, who drowned while on a holiday in France a few weeks after his construction of this space, which was then almost forgotten for 60 years before again attracting the attention of mathematicians. Melleray enjoys spending time with his family (three brothers and a wonderful 1-year-old niece) in the southwest of France, and when he has some spare time, loves reading; he is especially fond of modern American crime fiction, and has recently developed an unavowable liking for (really) bad science fiction novels.
Wendy Harris
Director of Budget and Resource Planning
Wendy Harris joined the Department of Mathematics as the Director of Budget and Resource Planning in June. She has been on campus for 12 years, most recently in a similar position at Educational Psychology. Wendy has two Masters degrees, but fears the Ph.D. process, so don't expect any more. When off-campus, Wendy can be found working for the Champaign-Urbana Theatre Company (management and techie only; none of that on-stage stuff) or shopping for antiques and books. Born and raised in the Midwest, she has recently discovered the joy of overseas travel, so expect her to be gone a couple of weeks each year!

MathCoUI continues work in local schools

The Mathematics Community Outreach at the University of Illinois (MathCoUI) is a student organization whose goal is to introduce, clarify, and make mathematics hands-on and enjoyable to students in middle and high schools. Going to various schools in the community, these students focus on topics that relate to the material teachers cover in each class. This organization was started in the Fall of 2005 with the idea of working with middle school math classes. By the end of its first year, MathCoUI was already working at both the middle and high school levels. This year they will continue to work with the schools in the Champaign-Urbana community to promote mathematics in fun and interactive ways. Visit their website for more information at http://www.mste.uiuc.edu/projects/MathCoUI/.

DARPA Grant: Sensor Topology and Minimal Planning

Article by Robert Ghrist, Associate Professor

"Imagine that you have thousands upon thousands of mobile video cameras and one of them catches something important. What do you do now? And, to make it interesting, let's assume that you don't have GPS, range finders, orientation sensors, or a compass. What now?"

Robert Ghrist and his colleagues are preparing to answer the "What now?" question through a research project called SToMP, short for "Sensor Topology & Minimal Planning." Funded by the Defense Advanced Research Projects Agency (DARPA), the $7.98 million project will cover three phases of development over four years. The multi-year, interdisciplinary project, SToMP brings together experts from the University of Illinois, Bell Labs/ Lucent, Arizona State University, Rochester University, Carnegie-Mellon University, Melbourne University, the University of Pennsylvania, and the University of Chicago who will "develop and implement global topological tools to dramatically reduce the amount of sensing complexity needed to solve problems across a variety of Department of Defense applications involving sensor networks, autonomous systems, and configurable sensor platforms."

"This is very much a forward-thinking project," Ghrist added. "As technology for sensors progresses, we will be able to replace large, expensive 'global' sensors with swarms of small, cheap, 'local' sensors. One of the problems with such a system is how to integrate all that local data into a global picture on an environment, and how to manage the information overload," Ghrist explained. To solve the problem, Ghrist and his colleagues have turned to a specific field of mathematics -- topology. Founded in the early 20th Century, topology is the study of abstract spaces. "After a century's work, we have a lot of tools that have yet to cross over into the engineering world. This project is all about that technology transfer." The idea of turning mathematical theories into useful tools is part of the attraction researchers. According to Ghrist, SToMP has two features that are pretty unique. "Number one is that it is a mathematics research project. The investment here is in theorems and algorithms, and a specific type of math -- topology," he said. "DARPA usually funds more hardware-oriented projects, however, the agency is known for preparing for the impossible that will nevertheless come to pass." In its role as the central research and development organization for the Department of Defense, past DARPA initiatives include global positioning technology and computer connectivity which has since become the Internet.

The second feature of the SToMP project, according to Ghrist, is its emphasis on minimality. "The question is: 'What's the minimum amount of sensing needed to solve a problem?' Sometimes you can solve a problem with a fairly simple or weak system," he explained. "One way mathematics can assist is by showing that certain modalities are not vital, which makes miniaturization and deployment easier." "It won't be long until the sensor networks are everywhere," Ghrist remarked. "The abilities we have to fabricate sensors are growing at an exponential rate. Our goal is to have the math ready when the hardware is available."

IMU announces new logo

Article by John Sullivan, Adjunct Professor

The International Mathematical Union (IMU) has adopted the new logo as announced on August 22, 2006 at the opening ceremony of the International Congress of Mathematicians (ICM 2006) in Madrid. It was the winner of an international competition announced by the IMU in 2004. The logo was designed by John Sullivan, Professor of Mathematical Visualization at the Technical University of Berlin (TU Berlin) and at the DFG Research Center MATHEON, and Adjunct Professor in the Department of Mathematics at the University of Illinois at Urbana-Champaign, with help from Prof. Nancy Wrinkle of Northeastern Illinois University. The logo design is based on the Borromean rings, a famous topological link of three components. The rings have the surprising property that if any one component is removed, the other two can fall apart (while all three together remain linked). This so-called Brunnian property has led the rings to be used over many centuries in many cultures as a symbol of interconnectedness, or of strength in unity. Although the Borromean rings are most often drawn as if made from three round circles, such a construction is mathematically impossible. The IMU logo instead uses the tight shape of the Borromean rings, as would be obtained by tying them in rope pulled as tight as possible. Mathematically, this is the length-minimizing configuration of the link subject to the constraint that unit-diameter tubes around the three components stay disjoint. This problem and its solution are described in the paper "Criticality for the Gehring Link Problem" by J. Cantarella, J. Fu, R. Kusner, J. Sullivan, N. Wrinkle, to appear in Geometry and Topology, 2006, and available at arXiv.org/math/0402212. Sullivan says the new logo "represents the interconnectedness not only of the various fields of mathematics, but also of the mathematical community around the world." Together with Charles Gunn of TU Berlin, he made a 5-minute computer-graphics video, "The Borromean Rings: a new logo for the IMU," for presentation at the ICM opening ceremony.

He was a Fellow, Institute of Mathematical Statistics, and an Elected member, International Statistical Institute. Philipp was an avid climber, making many first and repeat climbs in the 1950s. The Philipp-Flamm route in the Dolomites, for which he was named one of the top 100 climbers of the century, was considered a rite of passage for many famous climbers.

James Hunter Morris
James Morris of Carbondale, Illinois passed away in an automobile accident on September 16th. James graduated from UIUC with distinction in Mathematics. He was a second year law student at Cornell at the time of the accident and served as an associate editor of the Cornell Journal of Law and Public Policy. While at UIUC, James worked as a lead class assistant in the Calculus&Mathematica program. Professor Jerry Uhl remembers that "James established himself as a leader in the class and helped others students with their math and with the computer. By the end of the semester, he became hooked on math and went on to be an outstanding math major, excelling in computer-based and conventional math courses." Most of the students James worked with remember his bright sense of humor and quick wit. To many of his friends, he was known as Coconut. The James Hunter Morris Memorial Scholarship fund, designated for general student aid through the Vice Chancellor for Student Affairs' office, has been established through the University of Illinois Foundation.

Paul Halmos
Paul Halmos, famed mathematician, master expositor, author of several influential books, and originator of the "Halmos symbol" (the end-of-proof box), died on October 2, 2006 in Los Gatos, California. He was the author of more than a dozen books, many of them familiar to mathematicians around the world, and was acknowledged for his expository skill, both in writing and speaking. He received many awards during his lifetime, including the AMS Steele Prize (1983, for his many graduate texts) and the MAA Gung and Hu Award (2000, for distinguished service to mathematics). Born on March 3, 1916, in Budapest, Hungary, Halmos emigrated with his father, a physician, to Chicago, where he attended high school. He graduated from high school at age 15, then entered the University of Illinois, majoring in mathematics and philosophy. After receiving his bachelor's degree, he stayed at Illinois to pursue graduate studies, and he earned his Ph.D. in 1938 under Joseph Doob. While at Illinois, Halmos came to know many of the luminaries whose photos grace the halls of Altgeld Hall and whose names are attached to prizes and lecture series, and he spent part of that period living in Illini Hall, which at the time was a dormitory. Halmos describes his life at Illinois, in his own inimitable style, in his autobiography, "I want to be a mathematician" (Springer-Verlag, New York, 1985). Professor A.J. Hildebrand has prepared a webpage with excerpts from the book at http://www.math.uiuc.edu/~hildebr/halmosquotes.html.

André Dabrowski
André Dabrowski died October 7. He received his Ph.D. from the University of Illinois in 1982. Dabrowski then joined the faculty at the University of Calgary where he remained until 1985. From then on he was on the faculty at the University of Ottawa. At the time of his death Dabrowski was Dean of Science at the University of Ottawa.

Marianne Ruth Freundlich Smith
Marianne Freundlich Smith passed away at home in Berkeley, California on July 15. She was born in Karlsruhe, Germany and in 1934 fled to the United States with her parents and sister. She grew up in Queens, NY and attended Queens College. Freundlich Smith received her Ph.D. in 1947 at the University of Illinois. That same year, she moved to Berkeley, where she taught mathematics at the University of California, but when the loyalty oath became an issue, she refused to sign and quit teaching. Freundlich Smith later became a professor at California State College at Hayward (now California State University, Hayward), where she taught for 25 years. A description of her coming to understand analysis is in her article "Eventually" in the May 1998 Notices of the AMS.

Paul F. Conrad
Paul Conrad passed away on June 25 at the age of 84. Conrad received his degrees from the University of Illinois, culminating in his Ph.D. in 1951 under the direction of Reinhold Baer. He made significant contributions to the field of ordered algebraic structures. He taught at Tulane University from 1951 until 1970 when he accepted a professorship at the University of Kansas. He was a Fulbright lecturer at the University of Ceylon during 1956-57 and a NSF senior postdoctoral fellow at the Australian National University during 1964-65. In 1981, he was appointed the first Henry J. Bischoff Professor of Mathematics at the University of Kansas, and he retired in 1992.

Donald Higman
Donald Higman died February 13. He received his Ph.D. in 1952 from the University of Illinois Urbana-Champaign under the direction of Reinhold Baer and taught at the University of Michigan for many years. He and Charles Sims produced the sporadic group of order 44,352,000, now known as HS, the Higman-Sims group. He was 77 at the time of his death.
