lessTitle: Complementarity in Human-AI Collaborations
Abstract: Multi-agent decision pipelines (including human-AI collaboration) can outperform single agent workflows when complementarity holds, i.e., different agents bring unique information to the table to inform a final decision. In this talk, I will present a set of decision-theoretic frameworks we developed to measure and leverage complementarity in multi-agent decision-making. I will share examples of how these tools help diagnose when people should rely on AI, communicate what information is missing, and train language models to surface complementary signals from text to support better decisions.

Toward Faster Algebraic Computation: An Isomorphism PerspectiveAbstract
"Over the past few decades, linear-algebraic techniques played a central role in the design of faster algorithms, with notable successes in many graph algorithms such as maximum flow and shortest paths. However, for many problems that are not yet known to admit polynomial-time algorithms—such as integer factoring and various isomorphism problems—linear methods alone are often insufficient. In these settings, more general nonlinear algebraic structures, including groups, rings, and modules, naturally arise. Achieving further algorithmic progress requires a deeper understanding of these algebraic objects.
In this talk, I will discuss how algebraic representations have become essential to recent advances in isomorphism problems. I will highlight connections among several central isomorphism problems and survey the techniques that have led to more efficient algorithms. I will conclude by discussing open challenges and outlining promising directions for future research."

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
Austin Mordahl has been an Assistant Professor at the University of Illinois Chicago since November 2024. Prior to this, he was a Ph.D. student at the University of Texas at Dallas. Dr. Mordahl’s research concerns automatic bug detection and static analysis, and he is especially interested in understanding and improving the performance of real-world static analysis tools. As a Ph.D. student, he was a recipient of the prestigious NSF Graduate Research Fellowship as well as the winner of the 2019 ACM Student Research Competition at ICSE.Research Interests: Program analysis, software testing, software engineering

From Data to Design: Rethinking Engineering Design With Next-Gen AIAbstract
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.Biography
Faez Ahmed is an Associate Professor of Mechanical Engineering at MIT, where heleads the DeCoDE Lab. His research focuses on AI for engineering design, including deep generative models, multimodal representations, and human–AI collaboration. His work has been recognized with the NSF CAREER Award, ASME DAC and DTM Young Investigator Awards, the Google Research Scholar Award, and the Amazon Research Award. He serves as an Associate Editor for Computer-Aided Design and Design Science.TIME Monday, April 6, 2026 at 12:00 PM - 1:00 PM
