Adriana Weisleder is an assistant professor in the Department of Communication Sciences and Disorders and Director of the Child Language Lab. Her research investigates early language development and processing in young children growing up in a range of sociocultural backgrounds, with a focus on dual language learners. She uses multiple methodologies – including eye-tracking, naturalistic recordings, and studies of real-world interventions – to investigate both the learning mechanisms and contexts that support language development in infants and toddlers. An important goal of this work is to contribute to building a more robust evidence base for understanding typical and atypical language development across diverse contexts, and to reduce inequities in the identification and treatment of child language and communication disorders. Dr. Weisleder is a proud Costa Rican and Spanish-English bilingual.
