I'm a fourth year PhD student in Computer Science at the University of California, Davis advised by Professor Magdalena Wojcieszak. My research interests involve the privacy, societal, and safety implications of online algorithmic systems.


Prior to joining UC Davis, I worked at the Technology for People Initiative Lab on projects related to online privacy and media analytics.
