معرفی
Nathan Kallus is an Associate Professor at Cornell Tech and Cornell University, affiliated with the Department of Operations Research and Information Engineering (ORIE), as well as Computer Science (CS), Economics, Statistics, and Computational Applied Mathematics (CAM). His research focuses on data-driven decision-making, causal inference, optimization, and machine learning. Kallus holds a PhD from MIT and undergraduate degrees from UC Berkeley. He leads the Netflix Machine Learning & Inference Research team and advises students in topics like reinforcement learning, causal ML, and policy evaluation. His work bridges theory and practical applications, with contributions to A/B testing, off-policy evaluation, and spatiotemporal causal inference.
Education: PhD in Operations Research (MIT), BA in Pure Mathematics, BS in Computer Science (UC Berkeley). Current research emphasizes causal inference powered by ML, distributional RL for LLM post-training, and efficient sequential decision-making. Recent projects include GST-UNet for spatiotemporal data, Value-Guided Search for reasoning, and nonparametric IV inference. His work has been recognized for its methodological rigor and impact on fields like healthcare, digital platforms, and public policy.
Students and Collaborators: Advises PhD students (e.g., Antonia Oprescu, Kaiwen Wang) and alumni in academia and industry roles. Collaborates on projects spanning causal ML, fair AI, and large-scale experimentation. Recruits motivated PhD candidates for interdisciplinary research.
Labs and Teams: Research Director at Netflix’s Machine Learning & Inference group, leading work on decision rules, recommendation systems, and causal analysis. Active in Cornell’s ORIE department and affiliated with interdisciplinary initiatives in AI and statistics.
