# Mathematics Faculty Mentors

**Abdulaziz Elfessi**

Associate Professor of Mathematics

His area of expertise is in the field of applied statistics. He has
worked with several graduate and undergraduate students from many
different departments at the University on a variety of projects. He
joined the Mathematics Department in 1994 after teaching for 2 years at
University of Louisiana-Lafayette. Dr. Elfessi served as the Statistical
Consultant for the University of Wisconsin-La Crosse from 1996-1999. For
more information, e-mail him at:
elfessi.abdu@uwlax.edu .

**Robert Hoar**

Associate Professor of Mathematics

He is working with students on the "Mathematics E-Tutor", an expert
system that is web-based and which has the goal of teaching (or
tutoring) remedial math students. A student is creating the software
structure "behind the scenes" of the collection of web sites contained
at http://www.compute.uwlax.edu/expert/
. At this point you will see that the site does not contain too much
remedial math content, but the basic structure of the site (the hard
part) is nearly complete, thanks to the student working on the project.

The next step in the project is to develop the materials that will be placed on the "Mathematics E-Tutor." The "Student Developers" will be selected soon and will help fill in the blanks on the http://www.compute.uwlax.edu/expert/web site. The 4-6 student developers will be paid through an undergraduate research grant program developed by Dr. Hoar and Dr. Sobota. The program primarily targets Secondary Ed students in Mathematics (a group that does not have too many undergraduate research opportunities). The grant information is contained in a PDF file that can be downloaded from http://www.compute.uwlax.edu/expert/Call4Proposals.pdf .

**Susan E. Kelly**

Professor of Mathematics

Her research area is Harmonic Analysis with a specialty in Wavelets.
Students will have the opportunity to learn about Fourier analysis and
Wavelets. There are many applications for this mathematics including
signal compression for transmitting sound and images. For more
information, stop by her office or check out the student research
project at
http://math.furman.edu/~mwoodard/fuejum/content/volume6.html .

**David M. Reineke**

Assistant Professor of Mathematics in Statistics

Research involves constructing, testing and comparing goodness-of-fit
tests and using computer simulations to compare methods of estimating
lifetime distributions, particularly with randomly censored data. For
more information go to his web site at
http://www.uwlax.edu/mathematics/personal/reineke/
or e-mail him at:
reineke.davi@uwlax.edu .

**Bruce Riley**

Professor of Mathematics

His areas of interest are applied and computational mathematics. The
following includes samples of projects that he has directed: Numerical
Approximation of Interfacial Tension for Large Molecular Clusters, Early
Harmonic Analyzers, A Singular Integral Equation from Mechanics,
Modeling the Accumulation of Methylmercury in Fish, The Nodes of a
Xylophone, Maximizing the Harvesting Yield from a Fishery, and A
Non-Classical Family of Orthogonal Polynomials and Their Use in
Constructing Gauss-Type Numerical Integration Schemes. Contact him at
riley.bruc@uwlax.edu .

**Helen Skala**

Professor of Mathematics

Research involves axiomatic systems in finite geometries and other
problems in geometry accessible to mathematics majors. For additional
information e-mail her at:
