I am a member of the following groups at UC Berkeley:
EECS Algorithmic Decision Systems / Algorithms, Data, & Society (ADS) Reading Group
CSTMS Science & Technology Studies/History of Science & Technology (STS/HST) Working Group
I am funded by the NSF Graduate Research Fellowship Program (GRFP).
I am a 5th-year PhD student at UC Berkeley studying Theoretical Computer Science (TCS). I research the development of accountability mechanisms for data sharing systems, including statistical data analysis & machine learning. I currently utilize tools from cryptography such as interactive & zero-knowledge proofs, differential privacy, property testing, and robust statistics. Most of my theoretical works include proof-of-concept implementations demonstrating their practicality. More broadly, I am passionate about Cryptography & Privacy in social settings, grounded in the theoretical, the applied, & in Computer Security, as well as a Human-Computer Interaction (HCI) and Science, Technology, & Society studies (STS) lens, enabling connections to auditing, regulation, & policy.
In order to foster these connections, I am also pursuing the PhD Designated Emphasis in STS. Within material-semiotic STS, conceptual history of cryptography and design anthropology for privacy give me tools to think rigorously about the societal work done by mathematical abstractions, critically about the values embodied in my technical work, and imaginatively about what a more just science could look like, without falling into technosolutionism. Currently, I believe that utilizing the intellectual toolkit from cryptography is a promising way to tackle problems of algorithmic accountability given its ability to reason about parties with disparate resources, power, and goals and expand the solution space in surprising ways.
I am fortunate to be advised by Shafi Goldwasser and Avishay Tal. During undergrad, I was honored to receive mentorship in TCS from Paul Beame and Nicolas Pippenger, and in STS from Marianne de Laet. Before starting my PhD, I majored in mathematics at Harvey Mudd College, with a minor in STS.
Outside of research, I enjoy urban hiking & biking, going to art fairs & farmers' markets, playing cooperative board games & indie tabletop roleplaying games, reading mysteries, speculative fiction, & horror, and doing crafts such as wood carving, alcohol-marker coloring books, & meditative ink doodling. I have a long-standing love for my hometown of Seattle.
Also, a rec: as a grad student with many grad student friends, I know it can be tricky to find time for longer TRPG campaign games like DnD. Fortunately, there's a whole ecosystem of amazing one-shot, pick-up-and-play games out there which don't require a gamemaster or prepping a bunch of stuff in advance! Some recommendations broken down by genre, type of mechanics, and price:
