Research Interests:

I am generally interested in finding good algorithms for solving problems which arise in the approximation of functions or data. My main focus has been on problems of best approximation, which involve the minimization of a norm. This sometimes leads me into an investigation of more theoretical aspects of approximation problems. Also, approximation problems can be interpreted as examples of optimization problems or even as examples of problems in linear algebra. Therefore, I am also interested in these areas, in so far as they relate to approximation problems.
