I completed my Bsc, Msc, PhD at the University of the Witwatersrand where I taught for several years, in particular minorities. My Msc and PhD advisor was Doron Lubinsky, Full Professor at the Georgia Institute of Technology. The title of my PhD thesis was Weighted Approximation for Erdos Weights. I have taught students and minorities both in the United States and South Africa and been involved in student abroad programs. I have advised secondary school, undergraduate and graduate students.

I am currently doing challenging and interesting education outreach at Wayne Country Day School in NC, a private secondary school where I am building their AP Calculus Programs and working with minorities to build their student abroad program (China, South Korea). An exciting new current project involves working with colleagues at Duke on interdisciplinary mathematics teaching and a "math everywhere" day for 9th-12th grade students. I am also working part time for Wake Technical College teaching statistics for them. I enjoy using and teaching math in multidisciplinary ways.

My research interests are varied, see Publication list and Research interests. For example, I have worked in computer vision, signal processing (see my Cambridge Book with Willard Miller), harmonic analysis, finite fields, geometric analysis, numerical analysis, approximation theory, imaging. I enjoy working in a collaborative, multi-disciplinary environment making connections between mathematical areas.

My teaching interests are see (teaching interests) also varied. For example, I enjoy working with minorities, exceptional students, secondary and collegiate education, interdisciplinary education (concept versus technique), secondary and collegiate research. My undergraduate and graduate students can be found at the link students.

During my college career, I have been involved in exciting strategic planning at a department, college and senate level as well as research supervision, research building and grants (national and international).

Interesting and rewarding places where I have worked include The University of South Florida, The Katholieke Universiteit, Leuven, The Pennsylvania State University, The Institute for Mathematics and its Applications, University of Minnesota and The University of the Witwatersrand.

Here are some colleagues I have had rewarding interactions with over several years.

I have been a member of the American Mathematical Society Mathematics Research Communities Advisory Board and the American Mathematical Society Committees of Committees. I held a New Directions Research Professorship at the Institute of Mathematics its Applications, University of Minnesota in 2005-2006 and been part of an exciting and new Centre for High Performance Computing initiative at the University of the Witwatersrand.

I have also been a 2007 Summer Fellow, Air Force Office of Research (Dayton Ohio), a British Engineering and Physical Sciences Research Council (EPSRC) fellow (2005-2008), a Freda Lawenski Fund for Academic Excellence recipient(1997), a Rosterholtz Memorial Scholar (1996-1997) and the recipient of several other grants from for example NSF, DOD and EPSRC.
