Adrienne Williams (she/her)
Research Fellow

Adrienne started organizing in 2018 while working as a junior high teacher for a tech owned and operated charter school. She expanded her organizing in 2020 after her work as an Amazon delivery driver during the pandemic afforded her the ability to see that many of the same issues that caused her to leave the charter schools were happening at Amazon as well. Since then she has worked both on the ground and behind the scenes with activists, politicians, researchers, and everyday people to enact positive change in the tech, labor, and education industries by exposing and educating the public on how these industries harm and ways in which that harm can be reversed. She hopes her unique lived experience working within and organizing against these industries aids in pushing towards a more equitable society. Adrienne is currently a Public Voices Fellow on Technology in the Public Interest with The OpEd Project in partnership with The MacArthur Foundation; As well as a research Fellow at the Distributed AI Research Institute (DAIR) and Just Tech.

Ellen Berrey (she/her)
Faculty Affiliate

Dr. Ellen Berrey is Associate Professor of Sociology at the University of Toronto and an affiliated scholar of the American Bar Foundation. Her research investigates how organizations and movements advance, and thwart, progressive social change in the United States and Canada.
She is particularly curious about how cultural ideals – diversity, fairness, sustainability – get invoked, contested, and institutionalized in law and organizations. Motivated by the goals of understanding and supporting anti-racism movements, her current study with Alex Hanna, Nathan Kim, and collaborators investigates campus protest and responses by university administrations and police. With Fatima Al Saadie, her study of an anti-sustainability movement examines how conspiracy theory is politically mobilized by white, conservative, suburban homeowners and adopted in local government. She is the author of two books: The Enigma of Diversity: The Language of Race and the Limits of Racial Justice (U of Chicago Press 2015) and Rights on Trial: How Workplace Discrimination Law Perpetuates Inequality (U of Chicago Press 2017).
