Reilly Bergin Wilson is a scholar and activist focused on urban environments in which children play. She is a research associate of the Children’s Environments Research Group at the Center for Human Environments and a doctoral candidate in Environmental Psychology at CUNY Graduate Center. Through her research, Reilly has sought to understand the social production of environments built for play, using qualitative field methods and archival research. She is particularly interested in how play environments function as spaces through which competing social, economic, and political agendas are revealed. Reilly was a co-founder and the former Board Chair of play:groundNYC, a nonprofit organization that advocates for children’s right to play through the production of playworker-run environments, including operation of the only adventure playground in New York City, The Yard.
