Biography

I joined the Department of Human Development and Family Studies and the Department of Public Health at Purdue as an Assistant Professor in the fall of 2017. Prior to joining Purdue, I received a Ph.D. in Human Development and Family Studies and a M.P.H. (in Biostatistics) from Oregon State University in 2015, and completed a two-year postdoctoral fellowship at the University of California, Irvine. I have an interdisciplinary background (i.e., lifespan psychology, life course sociology, family studies, public health, and education) and extensive quantitative training that inform my research. Broadly, my research focuses on understanding children’s development of academic skills, executive function, social-emotional skills, and fine/gross motor skills. I am particularly interested in the role of environments, interventions, and policies for fostering academic success and wellbeing, especially in children facing increased levels of socio-demographic risk. My quantitative interests are primarily in longitudinal and multilevel modeling, structural equation modeling, and causal inference.
