Nathan Kallus joined the faculty at Cornell in July 2016 as an Assistant Professor in the School of Operations Research and Information Engineering. His research revolves around data-driven decision making, the interplay of optimization and statistics in decision making and in inference, and the analytical capacities and challenges of observational, large-scale, and web-driven data. His works span basic theory, effective methodology, and novel applications and has been recognized by awards. Prof. Kallus holds a PhD in Operations Research from MIT as well as a BA in Mathematics and a BS in Computer Science both from UC Berkeley. Before coming to Cornell, Prof. Kallus was a Visiting Scholar at USC's Department of Data Sciences and Operations and a Postdoctoral Associate at MIT's Operations Research and Statistics group.
