Research Interests

Preschool mathematics and reading, home numeracy and literacy environments, mathematics learning for dual language learners, behavioral and cognitive development, interventions for children at-risk of later mathematics difficulties

Biography

I joined the Purdue faculty in the fall of 2012 after completing a US Department of Education Institute of Education Sciences postdoctoral fellowship at the University of Illinois in the College of Education. I received my Ph.D. in Clinical Psychology from Florida State University in 2010. You could say that I study the ABCs of the 123s! In my research, I focus on understanding how young children in preschool through 3rd grade learn math and how to identify children at-risk for later math difficulties. My current focus is on developing and evaluating interventions using picture books and games to support preschool children's early mathematics skills. Over the last several years, and in collaboration with a professional author and illustrator, we've developed a series of six picture books with math concepts embedded in them. Through intervention studies funded by the Heising-Simons Foundation and the National Science Foundation we're currently evaluating how these books can be used to improve the early mathematics skills of monolingual English speakers and dual language learners (Spanish/English). In my lab we also study the home numeracy and literacy environment and how home factors affect children’s academic skills at preschool entry.
