## Welcome

I am Professor of Mathematical Sciences at Clemson University. My research
interests are in computational mathematics, specifically the numerical method development and analysis for solving nonlinear partial differential equations,
typically applied to fluid flow problems. Despite the interest in applications, my work is still quite mathematical, and a theme to my research is `Mathematical Analysis as a guide to practical computing'. More specifically, I am still a mathematician who proves theorems, but for the purpose of solving practical problems faster and more accurately.

I hold a B.S. in Mathematics from Duquesne University in Pittsburgh (minor in Computer Science) which I completed in 2000, an M.S. in Computational Mathematics also from Duquesne in 2002, an M.A. in Mathematics from Pitt in 2003, and a Ph.D. in Mathematics from Pitt in 2006 (advised by William Layton). I am involved in several research projects, and am advising several Ph.D. students. I also serve on the editorial board for International Journal of Numerical Analysis and Modeling.

I am a strong supporter (and lately also a defender) of Clemson's
tradition of having a Mathematical Sciences graduate program instead of the traditional Mathematics
program. Our graduates are trained to have a breadth of knowledge in Computational Mathematics,
Operations Research, Statistics, Analysis, Stochastics, and Algebra. Since most M.S. and Ph.D.
students in mathematics/mathematical sciences end up with a job that is different from their thesis
research (which includes if they take a teaching job at a 4 year school), this breadth of knowledge
allows them to be very flexible in industry and laboratories, and provides our graduates who become
teachers at 4 year colleges the ability to teach all undergraduate course offerings.

Those interested in mathematics genealogy can explore my mathematical lineage (at the Mathematics Genealogy Project).

Here is an

from Greenville News about a textbook I wrote with Timo Heister.
