She earned a Ph.D. in curriculum, teaching, and educational policy (emphasis in science education) from Michigan State University in 2010. Her current research focuses on conducting validation studies on assessments of science teachers’ instructional quality and content knowledge for teaching science. This research targets the use of these science teaching quality measures as summative assessments for licensure purposes and as formative assessment tools integrated within teacher education. She currently serves as principal investigator on four National Science Foundation (NSF) research projects (grant award #1621344, #1813254, #2037983, and #2032179). She has served on the editorial review boards of Innovations in Science Teacher Education and American Educational Research Journal, where she received the Outstanding Reviewer award in 2018. In 2019, she facilitated a working conference on the role of simulations in K-12 science and mathematics teacher education. More recently, she served on the planning committee for the NSF DRK-12 principal investigator conference. Prior to graduate school, she taught elementary school for five years in Montgomery County, MD, and earned her National Board certification during her tenure as a public school teacher.
