Adriana Weisleder's research investigates early language development and processing in young children from diverse linguistic and socioeconomic backgrounds, with a focus on dual language learners. She uses multiple methodologies – including eye-tracking, naturalistic recordings, and clinical trials of interventions – to investigate both the learning mechanisms and contexts that support language development in infants and toddlers. She also collaborates on the development of family and community-based approaches for reducing poverty-related disparities in children’s developmental and educational outcomes.
