Thumbnail Sketches and Web Links

This page provides links to all of my co-authors and co-editors who have web pages (and a few who don't). If I have made any errors in any of my thumbnail sketches, let me know and I will fix them.

David Aldous contributes to all parts of probability, but he has a particular liking for intuitive ideas like the famous clumping heuristic. His site provides (1) access to his new Markov Chain book with Jim Fill, (2) an open problems page, and (3) the *Top Ten Reasons to Become a Probabilist.

Alessandro Arlotto completed his Ph.D. in the OPIM department at Wharton in the summer of 2012. He is now Assistant Professor of Decision Sciences, Fuqua School of Business, Duke University. Look for him to rise quickly as leader in the area of Markov decision problems, sequential decision making --- and applied probablity in general.

David Avis is a professor of computer science at McGill who is best known for work in computational geometry. Remarkably, David is also fluent in Japanese, which he learned as an adult.

Jon Bentley is on anyone's list's of the greatest contributors to the world literature of programming. His books make **real **money. Our paper has been translated into Japanese.

David Boyd is a founder of what is now known as *experimental mathematics*. He is the man to ask if you have a question about Pissot-Vinnot numbers or Mahler's measure; for his work in this area he won the 2005 CRM-Fields Prize.

Shankar Bhamidi studied with
David Aldous and he works mostly on branching processes and distributional
functional equations. He is now an Associte Professor of Statistics at UNC. Our paper is
one of the few in the *Annals of Applied Probability* that mentions Lady
Gaga.

Sid Browne and I did work together when he was a professor at Columbia. He subsequently moved to Goldman, Sachs and he is now a Managing Director at Credit Suisse. He has not lost his widely admired capacity for humor.

Robert Chen works is an applied probabilist at the University of Miami who has worked on many selection problems and prophet problems.

Burgess Davis is a probabilist at Purdue. He is perhaps best known for the middle piece (in three senses!) of the widely used Burholder-Davis-Gundy inequality. He has also done much to show people how probablity theory can be used to prove theorems in complex analysis.

**Andres del Junco** did ergodic theory at the University of
Toronto. He passed away in 2015 at the age of 66.

Dick DeVeaux teaches statistics at Williams College, and, with Paul Velleman, he has written Intro Stats, which sells like hotcakes. Dick also has a worldwide reputation as a raconteur with a fine ear for dialect.

Persi Diaconis is as well-known as any statistician can be and one of the few with a picture in his Wikipedia profile. We've known each other since we were both assistant professors at Stanford. He's not here as a co-author but as a **co-editor** of that hard-to-find classic Discrete Probability and Algorithms.

Bill Eddy works in computational statistics and image processing at CMU. He is closely associated with a collection of image processing tools bravely named
*FIASCO*, or *Functional Image Analysis Software - Computational Olio*.

Marty Ellis died before our second paper could be published. No one understood the disease at the time, but it seems clear now that Marty was an early casualty of what we now call AIDS.

Andrey Feuerverger is at the University of Toronto, works in mathematical statistics and gained some notoriety for his paper on the so-called "lost tomb of Jesus" which appeared in the first volume of the *Annals of Applied Statistics. *

Jim Fill is a probabilist at Johns Hopkins known for his many works on Markov chains, including his eternally soon-to-be-finished book with David Aldous.

Moshe Fridman did his Ph.D. with me at Wharton, worked at UCLA for several years, then took up a career in bio-statistics and medical consultancy.

Noah Gans is the Joel S. Ehrenkranz Family Professor of OPIM at Wharton. Most of his work focuses on probability models and optimization applications in service operations manangement.

**Jun Gao** did his Ph.D. with me at Princeton in Applied and Computational Mathematics, though in his last year he was actually at Wharton. Gao has been working in the financial service sector for more than ten years now. Unfortunately, we have lost touch. If you know what Jun is doing now please let me know.

Nassif Ghoussoub has worked in many parts of non-linear analysis, optimization and partial differential equations, but when we were kids, we did ergodic theory together.

Joe Glaz is a statistician and probabilist at the University of Connecticut. He is a particularly involved with the investigation of scan statistics.

Floyd Hanson started out as a classical applied mathematician, doing fluids, asymptotics, and such. He then moved to less classical areas including parallel computation, computational finance, and scientific visualization. Floyd recently retired in order to devote his energy to writing books.

Dorit Hochbaum teaches both in Engineering and in the Haas School at Berkeley. Her research interests include algorithmic and probabilistic aspects of logistics, including supply chain management.

Dick Karp has contributed to many parts of discrete mathematics and the theory of algorithms. In particular he was among the first to realize the importance of NP-completeness and related notions of computational complexity. If there were Nobel prizes in computer science, he would have a couple.

Martin Kulldorff is a statistician at the Harvard Medical School who worked with Joe Glaz and Vladimir Pozdnyakov on scan statistics. As sometimes happens when a paper has multiple co-authors, I met Martin for the first time in 2009 more than a year after the publication of our paper.

Tom Leighton and I each have 20% ownership of a group paper organized by Jon Bentley. Tom is perhaps more famous as the co-founder of Akamai. He is my only billionaire co-author, though I hope there are many more.

** Margaret Lepley **is a computer scientist at Mitre Corporation who now mainly works in data compression for images.

Elchanan Mossel was Professor of Statistics at Berkeley until he recently saw the the wisdom of moving to Wharton. He works in many areas of probability, but perhaps he is best known for his work on discrete Fourier analysis and social choice theory.

Peichao Peng is currently a graduate student in the Department of Statistics at Wharton. He works both in probability and in computational statistics.

Vladimir Pozdnyakov did his first Ph.d. in St. Petersburg and then came to Penn to do a second Ph.d. He works in limit theory, mathematical finance, and other areas of applied probability, including scan statistics. He is now a Professor at UConn.

**Jim Zidek** was UBC's first Professor of Statistics, and he has recently become UBC's first Emeritus Professor of Statistics. You can read about Jim's career in English or in French.

Almost anyone in the mathematical sciences is likely to be amused by the Mathematics Genealogy Project . Here I learned to my surprise that I am a scholarly descendant of C. F. Gauss (by two paths):

- I got my Ph.D. in 1975 working with Kai Lai Chung at Stanford
- Chung got his Ph.D. in 1947 working with Harald Cramer (and vetted by John Tukey) at Princeton,
- Cramer got his Ph.D. in 1917 working with Marcel Riesz at Stockholm University,
- Riesz got his Ph.D. in 1912 working with Leopold Fejer at Eötvös Loránd University,
- Fejer got his Ph.D. 1903 working with Hermann Schwarz at Eötvös Loránd University,
- Schwarz got his Ph.D in 1864 working with Ernst Kummer and Karl Weierstraß,
so now we split the path:
- Weierstraß got his Ph.D in 1854 working with Christoph Gudermann in Königsberg,
- Gudermann got his Ph.D in 1841 working with
**C. F. Gauss**in Göttingen, - Kummer got his Ph.D. in 1831 working with Heinrich Scherk,
- Scherk got his Ph.D in 1823 working with Friedrich Bessel, and
- Bessel got his Ph.D. in 1810 from
**C. F. Gauss**.

I also recently checked my Erdös number, which I knew had to be two even without knowing by what path. Anyway, I found that David Avis has Erdös number one, so the paper Avis-Davis-Steele (1988) confirms that my Erdös number is in fact two.

Erdös and I had two pieces of work together, yet out of my laziness or foolishness they did not turn into publications. In one of these, Marty Ellis and I developed an idea which was in my thesis and for which Erdös had been the supplier of both the motivation and the key ideas. This is all duly acknowledged in the thesis, but it would have been infinitely better (and much more appropriate) to have had Ellis-Steele (1979) be Erdös-Ellis-Steele (1979). I sorely wish that it could be made so retrospectively.
