Grace Wahba has a B.A. in Mathematics from Cornell where she had the good fortune to have Mark Kac for calculus; an M.A. in Mathematics from the University of Maryland, College Park, where Ryszard Syski was her thesis advisor; and a Ph.D. in Statistics from Stanford University where Emanuel Parzen was her thesis advisor. Professor Wahba worked for Operations Research, Inc. and IBM before she got her Ph.D., was a post doc at Stanford, and is a John Bascom Professor of Statistics at University of Wisconsin, Madison. She is the author of a book "Spline Models for Observational Data" (SIAM 1990) as well as author or co-author of about 100 articles, chapters and so forth, applied and theoretical. Professor Wahba thinks the most fun is when a real world problem raises interesting theoretical issues. She is very proud of her many high-achieving former students.
