I'm a second year PhD student at the University of Pennsylvania in the Computer and Information Science department. I am grateful to be advised by Professor Danaƫ Metaxa as a member of Penn HCI. My work is supported by an AWS gift for research in Trustworthy AI.

Broadly my interests are in human-computer interaction, applied machine learning and computational social science with a current focus on algorithm auditing. Prior to Penn I worked in industry as a software engineer at Apple and Sisu Data. I studied Computer Science (MS) and Symbolic Systems (BS) at Stanford University.
