I am a final year Ph.D. candidate in the department of Computing and Information Science at Cornell Tech in New York City. I am advised by Helen Nissenbaum and James Grimmelmann.
My work sits at the intersection of human–computer interaction, privacy and security, and law and policy, with a focus on community governance.
I study governance through two arenas: privacy and intellectual property. My research investigates how governance mechanisms (e.g., privacy controls, licenses, and participatory protocols) enable or constrain how communities manage their data and participation. I work in partnership with communities and combine qualitative, sociometric, and computational methods with legal and policy analysis.
I am a member of the Digital Life Initiative, the Cornell Tech Research Lab in Applied Law and Technology, and an alumni of the Artificial Intelligence, Policy, and Practice Group (2021-2023).
For some time, I was the Digital Learning Specialist at Columbia University. I completed a Master in Information from the University of Toronto in 2016, and a Master of Arts from Columbia University in 2018.
