I went to Binghamton University (SUNY) in 1985 and earned a B.S. and an M.A. in Mathematics in five years of study. I continued my study of mathematics at Indiana University with the intent of getting a doctorate, but decided not to finish and instead earned a second M.A. in Mathematics in 1993. I found my interests and my professional energy were evoked by teaching and talking about teaching and learning, so I transferred to Indiana University's doctoral program in Mathematics Education. After three years of study, I had finished all my coursework and collected the data I needed to start writing my dissertation. I wrote the dissertation part-time for two years: one year working as a curriculum consultant for a multimedia courseware company, and another year as a new professor for the doctoral program in Mathematics Education at American University. I co-directed one dissertation and served on two other committees.. I did my own thesis on the development of mathematical sophistication in college students, and I am also interested in the ramifications of using technology in mathematics teaching and learning. My current research tends to be qualitative (based on interviews and observations) and focuses on students' ways of knowing mathematics and their motivations for learning it, particularly students at risk and students who want to become teachers. My vita includes a more detailed description of my research interests . I stayed for a second year at American University before joining the U.S. Military Academy (aka West Point) in June 1999, where I taught application-oriented calculus and discrete mathematics and continued my educational research. I remained for two years of my three-year nonrenewable appointment and started a tenure-track position at Montclair State University in the Fall of 2001. I teach mathematics at all levels, but my primary responsibility there is to the mathematics education programs - observing student teachers, delivering Master's courses, and mentoring doctoral students in the Ed.D. in Pedagogy program. I'm eligible for promotion in 2003 and for tenure in 2005.
