Paul Hagelstein grew up in Graham, Texas. Majoring in mathematics and physics, he received his undergraduate degree at Rice University. Subsequently he attended graduate school at The University of Chicago where he received a Ph. D. in Mathematics. After a three year postdoctoral fellowship at Princeton University, he joined the Baylor faculty in the fall of 2003. His primary research interest is in harmonic analysis, with most of his work involving geometric maximal operators, convergence of Fourier series, and interpolation theory. While not trying to prove theorems, he enjoys practicing the piano, playing the trombone in the Waco Community Band, and attempting to become a proficient tournament Scrabble player.
