A juggler in my college days, I was part of the circus act Bouncing Bears and have served as a judge for international trampoline competitions...after receiving my doctorate in mathematics from the University of California- Berkeley.

For my research contributions to scheduling theory, computational geometry, Ramsey theory, and quasi-randomness theory, I was described by the American Mathematical Society as "one of the principal architects of the rapid development worldwide of discrete mathematics...."

One of my odder contributions was a large number named after me, serving as the upper bound for my solution of a problem in Ramsey theory...now known as the "largest number ever used in a mathematical proof" (it is even listed as such in the Guinness Book of Records).

I spread the concept of the Erdős number in honor of my friend Paul Erdős (1913–1996), who I co-authored about 30 papers with...thus, my Erdős number is 1.

Currently, I am Chief Scientist at the California Institute for Telecommunication and Information Technology and a Computer Science professor at UCSD.

Having published about 320 papers and 5 books, I have been awarded the AMS's Steele Prize for Lifetime Achievement, inducted as a Fellow of the Association for Computing Machinery, and won the Pólya Prize, the Euler Medal, the MAA's Lester R. Ford prize, and the Carl Allendoerfer prize.

Somewhat outside of mathematics, I was President of the International Jugglers Association, have created new juggling tricks, and often teach the connection between juggling and mathematics to students.
