After nine years of life in Europe, I returned to the United States to attend Georgetown University in 1969. I lived outside of Washington, DC in suburban Alexandria, Virginia. At Georgetown I majored in mathematics graduating with a B.S. in 1973. I had developed a fondness for the southern states and applied to various graduate schools in the south. The University of South Carolina offered me an assistantship, so in 1973 I moved to Columbia finishing an M.S. in mathematics. My thesis was titled "Right Group and Minimum Right Group Congruences on a Semigroup" and was directed by H.E. Scheiblich.
As a graduate assistant I discovered a love for teaching mathematics and enrolled in the Ph.D. program in mathematics education in College of Education. I completed my course work and, in 1977, took a position as a teacher of mathematics at Spring Valley High School in Columbia. In 1979, I was appointed Department Head at that school and continued there until 1981. As my responsibilities at the school increased, I recognized the difficulty of completing my doctoral degree while working in a high school. I accepted a position in the Mathematics Department at Columbia College in 1981 and within a year finished my dissertation ("A Study Comparing Advanced Placement and First-Year College Calculus Students on a Calculus Achievement Test" directed by Jack M. Ott).
In 1984, I joined the faculty of the Department of Instruction and Teacher Education concentrating on technology in education as well as mathematics education. I have taught numerous video courses within the USC System and as part of the pilot SERC Star Schools project. I have also taught courses or conducted seminars at the International School of Kenya, the International School in Manila, Graded School in São Paulo, the Canadian Academy in Kobe, and the International School of Osaka. I have held several leadership positions with the National Council of Teachers of Mathematics including chair of the Editorial Panels for the Mathematics Teacher and ON-Math as well as program chair for the 1999 Annual Meeting in San Francisco.
My wife Karen is the Chief Operating Officer at Hammond School where our two children, Isabel and Ry, went to school. Isabel now lives in Seattle and Ry in Charleston. I play tennis, ski, and ride my bike as often as I can commuting to work when the weather and my schedule permit. I'm a fan of Gamecock Soccer attending as many games as I can, and when I'm really lucky, there's always a game feature Flamengo. I have never lost my love for traveling. Pictures from trips to Kenya and Italy are only a click away.
