Charles Louis Fefferman (born April 18, 1949) is an American mathematician at Princeton University. His primary field of research is mathematical analysis.

## Biography

A child prodigy, Fefferman entered the University of Maryland at age 14,[1][2][5] and had written his first scientific paper by the age of 15.[1] He graduated with degrees in math and physics at 17,[6] and earned his PhD in mathematics three years later from Princeton University, under Elias Stein. Fefferman achieved a full professorship at the University of Chicago at the age of 22, making him the youngest full professor ever appointed in the United States.[4] At 24, he returned to Princeton as a full professor—a position he still holds[needs update]. He won the Alan T. Waterman Award in 1976[2] (the first person to get the award) and the Fields Medal in 1978 for his work in mathematical analysis, specifically convergence and divergence.[1] He was elected to the National Academy of Sciences in 1979.[7] He was appointed the Herbert Jones Professor at Princeton in 1984.

In addition to the above, his honors include the Salem Prize in 1971, the Bôcher Memorial Prize in 2008,[8] the Bergman Prize in 1992,[9] and the Wolf Prize in Mathematics for 2017,[10] as well as election to the American Academy of Arts and Sciences.

Fefferman contributed several innovations that revised the study of multidimensional complex analysis by finding fruitful generalisations of classical low-dimensional results. Fefferman's work on partial differential equations, Fourier analysis, in particular convergence, multipliers, divergence, singular integrals and Hardy spaces earned him a Fields Medal at the International Congress of Mathematicians at Helsinki in 1978.

His early work included a study of the asymptotics of the Bergman kernel off the boundaries of pseudoconvex domains in ${\displaystyle \mathbb {C} ^{n}}$. He has studied mathematical physics, harmonic analysis, fluid dynamics, neural networks, geometry, mathematical finance and spectral analysis, amongst others.

## Family

Charles Fefferman and his wife Julie have two daughters, Nina and Lainie. Lainie Fefferman is a composer, taught math at Saint Ann's School (New York City) and holds a degree in music from Yale University as well as a Ph.D. in music composition from Princeton.[11] She has an interest in Middle Eastern music.[12] Nina is a computational biologist whose research is concerned with the application of mathematical models to complex biological systems.[13] Charles Fefferman's brother, Robert Fefferman, is also a mathematician and former Dean of the Physical Sciences Division at the University of Chicago.[14]
