In my research, my students and I examine various aspects of cognitive development and language learning in infants and young children. I am particularly interested in the interaction between cognition and language from infancy into early childhood. Much of my work has focused on the early development of spatial skills, the acquisition of spatial language, and links and causal relations across these two domains. Other work has examined how infants and children acquire a second language and this acquisition may shape underlying concepts.

In addition, our lab seeks to develop new methodological approaches that can be used to trace the trajectory of spatial and cognitive skills from infancy into early childhood. We combine across naturalistic and experimental methods to understand how acquiring spatial language may relate to the development of spatial skills and to test causal links between particular experiences, such as exposure to spatial language or engaging in particular play activities, and adavnces in infants' and children's spatial skills. Our goal is to not only understand how early spatial skills develop, but also how best to promote their development. 

In other work, my students and I have begun to explore how infants and toddlers learn labels in a foreign language, examining how much exposure to an unfamiliar language (such as Spanish) is necessary for infants to begin to demonstrate comprehension of words in the new language. We have also explored this question with school-aged children who are learning a new language (Spanish) during a weekly enrichment program.

My research integrates outreach and public engagement with the studies we conduct. As a former Faculty Fellow with Brofenbrenner Center for Translational Research, I develped important partnerships with Cornell Cooperative Extension to explores way to expand our study of early spatial skills to more diverse samples of young children thoughout NY state. Thanks to the assistance of the Brofenbrenner Center, we established critical new connections to Head Start Centers in Tompkins County and NYC and have expanded our experimental studies to these centers, allowing us to extend findings from the lab to classrooms to children's museums. The work with the Head Start centers are especially important in ensuring that findings we establish in the research lab replicate in other samples and in other contexts. We also work closely with paritcular centers to contribute to or offer parent education programs around play and learning.

In my courses and research lab , I strive to help students develop their critical thinking, a skill which I hope will be useful regardless of their career path. In my courses, I also focus on developing students' writing so that they gain confidence and proficiency in clearly communicating their ideas. In the lab, I strive to instill a sense of excitement for the process of discovery and encourage students to use their creativity in tackling a research question.
