William Cai

I am a PhD student in the Department of Management Science and Engineering at Stanford, working in the Stanford Computational Policy Lab. I research real-world decision making systems, with a focus on (1) designing algorithmic policies which are robust to and can efficiently ameliorate inequities, and (2) developing statistical methodology for assessing equity in complex systems. My work is supported by a Stanford Graduate Fellowship. I spent the summer of 2020 as a research intern on Facebook's Responsible AI team and worked as a RA at Microsoft Research New York in the computational social science group from 2017-2018 before starting my PhD.
