**EDUCATION**

PhD in Mathematics Education, 2000 University of Tennessee

MS in Mathematics, 1993, University of North Texas

BS in Mathematics, 1991, Washington Adventist University

**RESEARCH**

My research interests include studying the impact of Mathematics Specialists in elementary and middle school classrooms, using meta-analysis to analyze pedagogical practices in mathematics, analyzing the role technology plays in the mathematics classroom, and studying reform-based efforts in college algebra and calculus.
