Research Description
My research examines how individuals’ unique genetic dispositions dynamically shape and interact with their environments to influence personality and cognitive ability, and how these characteristics in turn affect meaningful life outcomes, including academic achievement, fertility, and social mobility. My research draws on behavioral genetic theory and methodology, with a particular focus on charting the pathways from genotype to behavior over development and across environmental contexts. Currently, I work with a variety of data types, such as genetically informative twin and family data, nationally representative longitudinal data, and cross-cultural data.
I also direct the Illinois Twin Project. Find out more about the project and sign up for research studies at: www.iltwins.com
