Research Interests:

Research: My main area of interest is spline theory, numerical solutions of partial differential equations, numerical integration, computer aided geometric design, geophysics, and atmospheric data analysis.

Research with undergraduate students: Beginner students interested in approximation theory will be able to explore approximation methods for curves in a plane: classical methods as well as more recent techniques for approximating natural shapes, such as leaves, or simple drawings such as comics. The process would involve all steps from data collection to programming methods in Matlab and analyzing approximation errors. For more advanced students, I would suggest problems involving surface approximations.
