ABSTRACT
Generative AI is transforming how we create, customize, and accelerate digital content. Yet applying these tools to engineering design introduces unique challenges, from maintaining precision under evolving requirements to working effectively in data-scarce environments and interpreting designer intent. In this talk, I will discuss these challenges and show how emerging engineering-focused foundation models are beginning to address them, reshaping workflows in areas such as vehicle design, CAD automation, and design optimization. I will highlight new opportunities enabled by generative AI that integrates multimodal data with engineering analysis and optimization, and present examples of AI-driven design co-pilots for engineering tasks. The talk will conclude with a perspective on how AI enables us to broaden design democratization, accelerate innovation cycles, and fundamentally reshape the role of engineers.

Challenges of Modern Static Analysis: Configuration, Flakiness and TestingAbstract
"Static analysis tools are essential for catching bugs early in software development, yet decades of research have failed to overcome fundamental barriers to their adoption: complicated configuration, high false positive rates, and failure to detect real bugs. Despite the proliferation of sophisticated tools for determining program properties and advances in underlying techniques, these challenges continue to hinder widespread adoption and effective use in practice. In this talk, we will explore solutions to three persistent problems that plague modern static analysis: configuration complexity, flakiness, and testing. First, we'll examine approaches to reducing the steep learning curves around tool configuration, making it easier for developers to deploy static analyzers in their projects. Second, we'll investigate techniques for addressing flakiness: when analysis tools produce different results on identical code, undermining developer trust in their results. Finally, we'll discuss methods for testing static analysis tools themselves: validating that tools correctly determine the program properties they claim to compute.
Throughout the talk, we'll also examine how large language models are reshaping approaches to each of these challenges and consider their potential to fundamentally transform static analysis workflows. Attendees will gain practical insights into emerging solutions to long-standing problems and new research directions in making static analysis tools more reliable and accessible."Biography

Arindam Banerjee, University of Illinois Urbana-ChampaignTalk Title
Reinforcement Learning and Control with Generative World ModelsAbstract
"Recent years have witnessed remarkable advances in generative modeling — from diffusion models and flow matching to autoregressive transformers and action-conditioned video models — that are rapidly closing the gap between learned simulators and the complexity of real-world dynamics. These developments open a principled path toward a new generation of reinforcement learning (RL) algorithms that harness the representational power of generative world models, naturally bridging model-based planning and model-free policy optimization within a unified framework.
In this talk, we introduce an inference-time policy optimization framework inspired by model predictive control (MPC), built around a pretrained policy and a learned world model (WM) of state transitions and rewards. While existing approaches use learned dynamics to generate imagined trajectories — either during training or at inference — they stop short of using those trajectory rollouts to optimize policy parameters on the fly. Our approach addresses this gap through a Differentiable World Model (DWM) pipeline that enables end-to-end gradient computation through WM trajectory rollouts, yielding inference-time policy optimization (ITPO) grounded in MPC. Across continuous-control benchmarks, ITPO with DWM consistently outperforms strong offline RL baselines. Beyond the core RL framework, we also discuss principled approaches to fine-tuning generative models under distribution shift, which enable the online deployment of such world-model-based policies."

Lev Reyzin, University of Illinois ChicagoTalk Title
On the Hardness of Learning Regular ExpressionsAbstract
"Despite the theoretical significance and wide practical use of regular expressions, the computational complexity of learning them has been largely unexplored. We study the computational hardness of improperly learning regular expressions in the PAC model and with membership queries. We show that PAC learning is hard even under the uniform distribution on the hypercube, and also prove hardness of distribution-free learning with membership queries. Furthermore, if regular expressions are extended with complement or intersection, we establish hardness of learning with membership queries even under the uniform distribution. We emphasize that these results do not follow from existing hardness results for learning DFAs or NFAs, since the descriptive complexity of regular languages can differ exponentially between DFAs, NFAs, and regular expressions.
This work is joint with Idan Attias, Nati Srebro, and Gal Vardi"

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."
