Assistant Professor, Smead Aerospace
Friday, Oct. 4 | 10:40 a.m. | AERO 111

Abstract: As autonomous systems become increasingly prevalent in safety-critical domains, ensuring their safe operation remains a key challenge. This seminar examines the questions: Are we there yet? Have we achieved the level of safe autonomy needed for widespread deployment? The talk will focus on integration of three foundational elements—learning, control, and decision-making—through the lens of formal reasoning.

I will discuss how machine learning enables adaptive behavior in dynamic environments, but often lacks guarantees needed for safety. Control theory provides robust frameworks for system stability but faces limitations when navigating complex, uncertain settings. Decision-making strategies offer high-level guidance, yet can struggle to align with real-world constraints. I argue that formal methods offer a powerful and critical solution to bridging these gaps, providing mathematical guarantees for system behavior while accounting for the uncertainties inherent in autonomous decision-making.

I will present our progress in unifying these approaches to enable safe autonomy, addressing both the theoretical advancements and practical challenges. Specifically, I will highlight our key contributions to enabling assured, reliable, and interactive autonomy.

Assistant Professor, Smead Aerospace
Friday, Sept. 20 | 10:40 a.m. | AERO 111

Abstract: Lightweight materials and structures are essential in the aerospace industry, from enabling the large space structures required to advance science missions to reducing fuel consumption. Their mechanical response is often a result of the interplay between material properties and their geometry across different scales. As an example, we will present our work on high strain composites for deployable structures. First, how thickness controls the mode of failure of composites under bending. Second, how the geometry of composite flexures determines the balance between stiffness when deployed and compliance for better stowage. Finally, how curvature in composite booms can enable the ultra-lightweight booms necessary for the next generation of solar sails. We will also discuss other examples of our work, from ablative composites in hypersonics to animal architecture.

Friday, Sept. 27 | 10:40 a.m. | AERO 114

Abstract: Our future in space involves miniaturized satellites for low-cost and rapid access to space, autonomously navigating spacecraft, on-orbit servicing for sustainability, in-space assembly of critical infrastructure, formations for multi-point measurements, and spacecraft visiting the farthest reaches of our solar system. Across this wide array of architectures, form factors, and destinations is a common thread: spacecraft operating within multi-body gravitational systems. These systems possess a chaotic solution space that has challenged several astrodynamics tasks, including 1) sufficiently understanding the broad array of possible motions for a spacecraft; 2) designing complex and constrained trajectories that exist across a diverse trade space; 3) generating digestible predictions of the possible future motions of an object; and 4) automating all these tasks to reduce operational costs and support autonomous decision-making. This talk will present selected recent contributions from my research group to address these challenges by developing new trajectory analysis, design, and prediction strategies for spacecraft operating in multi-body systems.

Friday, Sept. 6 | 10:40 a.m. | AERO 114

Abstract: Autonomous cyberphysical systems hold the promise to positively transform many tasks, for example transportation, collecting scientific data in hazardous environments, and monitoring objects in space. Uncertainty is a critical factor in all of these domains. The partially observable Markov decision process (POMDP) and partially observable stochastic Game (POSG) provide mathematical formalisms for computing the best single-agent and multi-agent policies in the presence of uncertainty, however, these problems are notoriously computationally difficult to solve.

Recent work in the Autonomous Decision and Control Lab (ADCL) at CU �鶹ӰԺ has shown that one source of intractability, namely the curse of dimensionality in the state and observation spaces, is possible to overcome, both theoretically and practically. This presentation will give an overview of the ADCL's efforts to develop new theory and algorithms to solve POMDPs and POSGs and deploy the algorithms to solve real-world challenges.

Friday, April 26 | 10:40 a.m. | AERO 120

Abstract: Delaying the onset of turbulent flow, even by a small percentage, can significantly improve the capability of Air Force assets by reducing fuel expenditures while increasing the range of operation.

One method of transition from laminar to turbulent boundary layers is through the growth of Tollmien-Schlichting (T-S) waves. In 2015, a passive technique to reduce the magnitude of T-S waves was numerically demonstrated by Mahmoud Hussein from the University of Colorado, �鶹ӰԺ. The method attached a phononic crystal (PnC) to the interior of an airfoil panel with a band gap designed to cause destructive interference of T-S waves. In contrast to existing methods for delaying turbulent transition, PnCs are fully passive (no electrical power or pneumatics required) and do not modify the external surface of the aircraft. In this talk, the evolution in research on phononic subsurfaces for flow control will be discussed.

This includes efforts to reduce the size of phononic subsurfaces to fit into a wing, modeling the flow over a phononic subsurface using computational fluid dynamics simulations, model- informed design of phononic subsurfaces, determining the role of phase between the T-S wave and PnC response, and the challenges in experimentally achieving passive transition delay.
