Specialty area(s)

My areas of research are Harmonic Analysis and Mathematics History focusing on stories that tell a social justice story. I work with undergraduates on much of this research.

Student Research topics:

In both analysis and math history, I have had students present at State and National conferences of the Mathematical Association of America (MAA), at National Conference of Undergraduate Research (NCUR), and at the Research in the Rotunda. Several students have published papers.

Analysis Research:

One area of specialty for me is Harmonic Analysis. This is a topic that students can study after some background in Real Analysis or Mathematical Physics and Linear Algebra. Several of my papers can be read by students. One paper students may want to see is my paper on the mathematics of how compact discs are made Compact Discs and Sampling Theory . This paper explains how the Shannon Sampling Theorem (discovered in the 1940's) is used to digitize music. This paper was published in the Undergraduate Mathematics and Its Applications (UMAP) Journal. If you cannot gain access to the paper at the above link, you could also ask me for a copy. Student research projects in analysis have been done in Wavelet theory and Fourier Analysis. One student project in Harmonic Analysis can be found at Student Analysis Paper

Math History Research (Roles of Women and Minorities in Mathematics):

I also work with students on Math history projects which focus on women and minorities. This is an area that students can work in even early in their studies. The following paper I did with one student was published in the Notices of the American Mathematical Society and was also translated for distribution in China Notices Article . Two of my students did a paper on  Christine Ladd-Franklin . She was the American first woman to "earn" a PhD in mathematics, but she did not receive the degree for about 50 years since the school did not award degrees to women at that time. I usually have ideas for new such projects that can be long or short.

If you are interested in research in Analysis or Math History, please come talk to me.

Brief biography

Outside of work, I enjoy oil and water color painting as well as photography.  Snow skiing, water sports and biking are some activities I do with my family and love to travel when I get the opportunity.  I enjoy gardens, but I don't think I would miss the weeding.  I am a big fan of science and love hearing about new explorations and discoveries.

Susan Kelly, Mathematics & Statistics, co-authored the article "Guido Weiss: From immigrant boy to internationally renowned mathematician" in Journal of Geometric Analysis, Special Issue Dedicated to Guido L. Weiss and was accepted for publication by Springer. This paper was written with co-author Dr. Rodolfo Torres, Vice Chancellor for Research and Economic Development at the University of California Riverside. The paper presents the life of Professor Guido Weiss, who came to the United States as a ten-year old Jewish refugee from Italy during WWII and became an internationally respected mathematician, whose research and teaching career spanned over sixty years of active work. The paper highlighted many of his most important contributions to the field of Harmonic Analysis. Kelly's research was funded with a 2020 UWL Faculty Research Grant.
