Charles Anthony Micchelli (born December 22, 1942) is a distinguished American mathematician recognized globally for his contributions to numerical analysis, approximation theory, and machine learning.
Biography
Micchelli was born in Newark, New Jersey, into an Italian-American household. He completed his secondary education at Newark's East Side High School and subsequently obtained a bachelor's degree in mathematics from Rutgers University–New Brunswick in 1964. He earned his doctoral degree from Stanford University in 1969 under the supervision of Samuel Karlin, concentrating on approximation theory, motivated by a course on Chebyshev polynomials led by Gábor Szegő.
Acknowledging the increasing significance of computational methods and numerical analysis, Micchelli pursued further studies in computer science at Uppsala University. Upon returning to Stanford, he was invited by IBM scientist Theodore J. Rivlin to join the mathematical sciences division at the Thomas J. Watson Research Center, where he conducted research between 1970 and 2000. Throughout this time, he held visiting academic positions at more than twenty institutions worldwide. After retiring from IBM as emeritus in 2000, he accepted a professorship in mathematics at the University at Albany, SUNY, where he served until his retirement in 2016.
With over 275 scholarly articles authored, Micchelli is recognized as an ISI Highly Cited Researcher. His scholarly work encompasses areas such as the theory of total positivity, multivariate splines, refinability, geometric modeling, wavelet theory, interpolation using radial functions, neural networks, and theoretical aspects of machine learning. His research played a role in advancing I. J. Schoenberg's methodology for cardinal L-splines in 1974. In 1983, he was an invited speaker at the International Congress of Mathematicians held in Warsaw.
His extensive international collaborations include a long-term association with the University of Zaragoza (UNIZAR), where he spent a sabbatical year during 1988–1989 and co-led a NATO Advanced Study Institute focused on Computation of Curves and Surfaces in 1989. In recognition of his contributions, UNIZAR awarded him an honorary doctorate in 1994.
In 1991, Micchelli co-established the journal Advances in Computational Mathematics and served as its founding co-editor-in-chief along with John Charles Mason. Additionally, he has served on editorial boards for multiple international academic journals.
He married Patricia in 1965; together they have two children. Their son, Craig A. Micchelli, joined the developmental biology faculty at Washington University School of Medicine in St. Louis in 2006.
