Digital Safety and Security for Survivors of Interpersonal Abuse
We are an interdisciplinary group of researchers at Cornell Tech studying how to improve digital safety and security for survivors of intimate partner violence (IPV). Our work combines foundational research with community engagement to ensure technology empowers those working to end IPV and related social ills.
​
We also run the Clinic to End Tech Abuse (CETA) and offer free resources for IPV survivors in New York City.
