Birthday Symposium and von Karman Prize Crown Keller's Stellar Career

In celebration of a lifetime of professional achievement, Herb Keller, CRPC site director and applied mathematics professor at Caltech, will be honored on his seventieth birthday with a two-day symposium. The Department of Energy, the Engineering and Applied Science Division of the California Institute of Technology, and the CRPC are sponsoring the event, which will take place June 19-20, 1995 on the Caltech campus in Pasadena, CA. The symposium will begin the morning of June 19 and will feature a reception and banquet dinner that evening at the Caltech faculty club.

Through his research, participation in editing journals, and the graduate students he has mentored, Keller's contributions to computational mathematics are far and wide in their impact. The methods he has helped to develop to aid scientists and engineers in solving complex problems with computers include the "box scheme" for solving boundary layer problems in the aircraft industry; the method of "multiple shooting" to solve ordinary differential equations; and the "path-following" methods, for solving bifurcation problems in all fields of science. He is the co-author, with Eugene Isaacson, of the text "Analysis of Numerical Methods," which is a classic in the mathematics field and has been read by generations of students. (For more information on Keller's work, see the "Parallel Profile" article on him in the January 1995 issue of Parallel Computing Research.) Last summer at the SIAM Annual Meeting in San Diego, Keller was awarded the prestigious von Karman Prize. The prize is given every five years in recognition of an individual's contributions to the application of mathematics, to mechanics, or to engineering. At the meeting, Keller discussed parameter-dependent problems for which the number of solutions that exist changes as the parameters change.

"The von Karman prize is one of the highest awards a mathematician can achieve," said CRPC director Ken Kennedy. "I'm very excited that Herb received the award and consider it an honor to be working with him through the CRPC." Among the factors in selecting him for this award, SIAM cited Keller's contributions to bifurcation phenomena (particularly his work on the widely used AUTO code) and his "exemplary" service to the mathematics community as SIAM president (1975-76) and as a member of several SIAM committees and the editorial boards of several SIAM publications. The award, along with the symposium, highlights a career that is hopefully a "benchmark" to us all.
