Kenny Peng

I am a second-year computer science PhD student at Cornell, where I am fortunate to be advised by Nikhil Garg and Jon Kleinberg. Previously, I completed my undergraduate degree in mathematics at Princeton, where I was lucky to work closely with Arvind Narayanan and Evita Nestoridi.

I am based at Cornell Tech in New York City, where I am also a doctoral fellow at the Digital Life Initiative (DLI). I am also a member of Cornell's AI, Policy, and Practice (AIPP) working group.

I study the use of machine learning and algorithmic decision-making in societal settings.
