Welcome to the Field Lab! We are a research group at the Johns Hopkins University, affiliated with the Center for Language and Speech Processing. Our research sits at the intersection of natural language processing, social science, and ethics, with the broader goal of developing solutions to mitigate harms in technologies with societal impact, and critically examining how AI systems are developed and deployed.
