lessThe legal system is built upon complex bodies of written text that function as operative rules governing rights, obligations, and outcomes. Recent advances in natural language processing have created new opportunities to automate aspects of legal analysis using language models (LMs). However, these models remain fundamentally probabilistic systems optimized for statistical prediction rather than faithful rule application. As a result, they often generate fluent legal language while failing to perform the precise, multi-step reasoning required to correctly interpret and apply legal rules. This dissertation investigates how language models can be improved and rigorously evaluated as legal reasoners through the integration of symbolic representations and methods grounded in legal domain knowledge.
Focusing on a tractable subset of legal tasks termed computational legal reasoning, this work develops neurosymbolic approaches that structure legal interpretation, rule application, and evaluation. First, it introduces a system for transforming natural language contracts into machine-readable representations through the extraction of Obligation Logic Graphs (OLGs), enabling contractual obligations to be represented as structured logical relationships and translated into executable code. Second, it presents Chain of Logic, a prompting method designed to improve rule-based reasoning in language models by decomposing compositional rules into their constituent elements before recombining the results to reach a final conclusion. Third, it introduces OpenExempt, a dynamic framework and benchmark that generates natural language legal tasks and their solutions from expert-crafted encodings of statutes and case facts, enabling fine-grained diagnostic evaluation of model behavior across controlled variations in reasoning complexity and task structure. Together, these contributions advance the study of language models as legal reasoners by introducing methods that improve interpretability, reliability, and diagnostic evaluation.

From Research to Reality: The Applied AI PlaybookAbstract
Winning an AI benchmark is a feat; serving billions of users across multiple different surfaces is an entirely different challenge. This talk explores the Applied AI frontier at Google, focusing on the rigorous engineering required to bridge the gap between theoretical research and global-scale production. We will dissect the "Well-Lit Path" to production, addressing ease of use, compute efficiency, and non-AGI machine learning, all of which are important to imbue products with AI.Biography
I lead the Applied ML team at Google, where our mission is to enable the best AI across Google's product ecosystem. My team develops end-to-end solutions for teams applying AI to their products, focusing on model selection, prompt engineering, supervised fine-tuning/LoRA, distillation, model upgrades, etc.
Before this role, I led the onboard software team at Waymo, working to realize the mission of making it safe and easy to move people and things through autonomous driving technology.
My earlier tenure at Google spanned 15 years, most recently as a Distinguished Engineer. During that time, I co-founded Sibyl, a general-purpose, large-scale machine learning and data analysis system. My career also includes more than a decade of research at IBM, split between the Almaden and T.J. Watson Research Centers.
I received my B.Tech. in Computer Science from the Indian Institute of Technology, Kanpur—where I first met Professor Khuller—and earned my Ph.D. in Computer Science from Cornell University. In 2010, I was a co-recipient of the Dijkstra Prize (alongside Sam Toueg and Vassos Hadzilacos) for the research conducted in my Ph.D. thesis.

lessData privacy has become a major concern in machine learning and other applications of data processing. Differential privacy, a particular form of data privacy, has emerged as a powerful and rigorous approach to defending against a variety of privacy attacks. This approach involves a fundamental trade-off between privacy and accuracy (or utility), and one must carefully manage this trade-off in algorithm design. In this talk, I will explore a new notion of privacy, called relative privacy, which is based on the information-theoretic notion of relative entropy. An intriguing feature of relative privacy is that it is decoupled from accuracy in the sense that some algorithms can simultaneously provide perfect accuracy and near-perfect relative privacy. In some cases, one can make a relatively private algorithm also differentially private simply by perturbing the data at the algorithm input. I will describe a new gradient-descent method for distributed optimization that guarantees both perfect accuracy and near-perfect relative privacy, both from participating computational nodes and from eavesdroppers, under simple topological conditions on the communication graph.
Randy Freeman received a Ph.D. in Electrical Engineering from the University of California at Santa Barbara in 1995, after having received B.S. and M.S. degrees in EE from Cornell University and the University of Illinois at Urbana-Champaign (respectively). He joined Northwestern University in 1996, where he is currently a Professor of Electrical and Computer Engineering. He received the National Science Foundation CAREER Award in 1997, as well as best paper awards from the Asian Journal of Control (2013-2014) and the IEEE Control Systems Magazine (2021). He received his department's best teacher award twice, first in 1998 and again in 2025. His research interests include nonlinear system theory, nonlinear control, robust control, optimal control, and distributed control and estimation.

Bill Fefferman, University of ChicagoTalk Title
Have we seen a demonstration of experimental quantum advantage?Abstract
"A major goal for the field of quantum computation is “quantum advantage" -- the first experimental demonstration of a quantum computation that is beyond the capabilities of any classical computer. While we have now seen many quantum advantage claims made by experimental groups around the world, many of these claims have been disproven.In this talk we'll discuss the status quo regarding the latest experimental quantum advantage claims and the evidence for their classical hardness. We’ll then discuss the classical verification problem, and propose a new quantum advantage proposal that uses ideas from quantum error correction to enable a large gap between classical verification and simulation."
Biography
"Bill Fefferman is an Associate Professor in the Department of Computer Science at the University of Chicago. His research explores the power of quantum computers in both the near-term and the indefinite future. He is the recipient of an NSF CAREER award (2020), a Young Investigator Award from the Air Force Office of Scientific Research (2018), and a Google Scholar Award (2022). Before coming to Chicago he held research positions at the University of Maryland/NIST and at the University of California at Berkeley. He received his Ph.D. in computer science in the Department of Computer and Mathematical Sciences and the Institute for Quantum Information and Matter at Caltech."Research Area/Interest: Quantum computing, theory

lessSecure multi-party computation (MPC) enables multiple parties to jointly evaluate a function on their private inputs without revealing any information beyond the output. It is a foundational tool for privacy-preserving applications, including federated analytics, private machine learning, distributed credential issuance, and differentially private data release. Despite decades of progress, a persistent gap remains between the theoretical efficiency of MPC protocols and the performance and usability demands of real-world deployments.
My work is motivated by a core goal: to build secure computation frameworks that are \emph{provably efficient} while remaining \emph{practical for real-world developers}. I work across three areas: (1) generic MPC protocol design, (2) compiler frameworks for MPC, and (3) application-driven cryptographic systems, including differential privacy and thresholdizing standardized post-quantum signature schemes. I propose to build an efficient threshold version of the NIST-standardized FALCON signature scheme along two complementary directions: FALCON-specific algorithmic improvements, including a fixed-point analysis of the fast Fourier orthogonalization sampler to reduce the asymptotic signing complexity, and improved MPC primitives, including more efficient correlation generators applicable to both FALCON and ML-DSA.

Prabhakar RaghavanTalk Title:
Can AI assist in Mathematics and Computer Science research?Abstract:
We share our experience using LLMs to obtain new results in mathematics and computer science. We begin with an illustrative example from load-balancing in planet-scale cloud systems, outlining the abilities and limitations of LLMs. Next, we describe our experience with AlphaEvolve, an evolutionary language model from Google DeepMind, to establish new results in the approximability of the Traveling Salesman Problem (TSP), and MAX-CUT problem. We also derive new bounds for several Ramsey numbers. Our methodology entails evolving fleets of Python programs that generate proof chunks to yield these results, and to accelerate proof verification by up to 10,000x. We suggest that our results on inapproximability and Ramsey theory could not have been discovered by hand, and conclude with reflections on the state and promise of AI in mathematics and CS research.Biography:
Prabhakar Raghavan is the Chief Technologist at Google, where he has held several senior roles since joining in 2012, including Senior Vice President with oversight of Search, Maps, Advertising, Gemini and Payments, and before that, responsibility for Gmail, Google Drive, Calendar and Google Docs. Previously, he led Yahoo! Labs and served as CTO at Verity, Inc following over a decade at IBM Research. He co-authored the textbooks Randomized Algorithms and Introduction to Information Retrieval. Raghavan received a PhD from Berkeley and a Dottore ad honorem from the University of Bologna, and is a member of the National Academy of Engineering.---
