She teaches courses focused on mathematics teaching and learning to preservice and practicing teachers. Her research focuses on how quality of mathematics instruction is measured in elementary classrooms. She also examines how elementary teacher education, both preparation and professional development programs, can impact mathematics instructional quality with a particular focus on teachers’ specialized content knowledge. Much of her work in both research and teaching is grounded in her nine years of experience as a public school educator in Virginia. During that time, she worked as a sixth grade mathematics teacher, a mathematics specialist, and an assistant principal.
