I am a Professor in the Department of Mathematics at Texas A&M University in College Station. I have the University title of Presidential Professor for Teaching Excellence and the System title of Regents Professor.
The mathematics classes that I teach range from first-year calculus to graduate seminars and from analysis to algebra to applications. My favorite course is whatever I am teaching currently.
My main area of research is the theory of functions of complex variables. Together with my Texas A&M colleague Emil J. Straube, I received the 1995 Stefan Bergman Prize from the American Mathematical Society for contributions to the boundary regularity theory of the inhomogeneous Cauchy–Riemann equations on pseudoconvex domains in multidimensional complex space.
I am interested too in the effective communication of mathematics. I have served as Editor of the book-review column in the American Mathematical Monthly (1998–1999) and as Editor of the Notices of the American Mathematical Society (2001–2003). My article Reflections on the Arbelos received the 2009 Chauvenet Prize, the most prestigious award for mathematical exposition given by the Mathematical Association of America.
My mathematical genealogy traces back to David Hilbert, and my Erdős number is two.
