My work has generally been focused on the interplay between algebra and geometry in the construction and study of new infinite families of finite generalized quadrangles, non-classical ovals in finite desarguesian projective planes of even order, and in some cases new families of finite projective planes. This work has afforded me the opportunity to serve as a visiting research faculty member on several occasions at universities in Belgium, Italy and Australia. Recently I have begun to indulge my interests in algebraic number theory and its use in finite geometry, and hope to expand my research expertise to include algebraic number theory in my work. At the present time, Dr. Laurel Rogers (University of Colorado at Colorado Springs, Professor Emerita) and I are writing a major monograph titled TOPICS IN FINITE GEOMETRY: OVALS, OVOIDS AND GENERALIZED QUADRANGLES.
