Daniel Ngo

I am a fifth-year Ph.D. student at the University of Minnesota, co-advised by Professors Steven Wu and Maria Gini. I’m currently visiting Carnegie Mellon University at Software and Societal Systems Department.

My research interests lie in the intersection of machine learning, algorithmic game theory and econometrics. I am particularly interested in online machine learning and exploration-exploitation tradeoff, and their impact in socioeconomic environments. My current work focuses on bandit algorithms, differential privacy, federated learning, and strategic learning.

I received a B.S in Computer Science and Mathematics from Dickinson College, where I worked on a Genetic Algorithm honor project with Professor Grant Braught.

I am happy to talk about bandit algorithms and incentivizing exploration. Feel free to contact me at ngo00054 [at] umn.edu.
