Hello! I'm a researcher and long-time technologist interested in algorithmic fairness and AI accountability. I work on policy research, technical AI evaluation, and implementing ethics in real-world systems. I also help organizations navigate emerging AI regulations and standards.
Recently, I've been developing methods to evaluate fairness when LLMs summarize case documents in high-stakes contexts, including insurance underwriting and immigration decision-making.
Much of my research has been on the use of technology in border systems. I investigate privatized visa processing, facial age estimation and other biometrics, automated decision-making about travelers, and the grassroots technical responses to these measures. I combine ethnographic and technical methods in my work.
