Many real-world missions, however, require satisfying logical precedence constraints: collecting resources before accessing restricted zones, completing subtasks in a prescribed order, or acquiring tools before they can be used. This talk presents the augmented graph of convex sets (augmented GCS) framework, which unifies continuous trajectory optimization and combinatorial task sequencing within a single optimization problem.<br>\r\nThe key insight is that a layered augmented GCS, built on an exact convex partition of the free space, simultaneously selects an optimal task completion sequence and computes an optimal continuous trajectory. A shortest path in the augmented GCS solves both problems at once, yielding an exact solution up to a finite Bézier curve parameterization. The layered structure of the augmented GCS turns out to implement precisely the Bellman-Held-Karp (BHK) dynamic programming algorithm for the Traveling Salesman Problem, establishing a formal correspondence between our framework and the combinatorial TSP literature. This makes augmented GCS a continuous-geometry generalization of BHK, achieving the same singly exponential worst-case complexity, an exponential improvement over general-purpose temporal logic tools. We further develop a library of mission specification variations (including ordered collection, disjunctive keys, conjunctive doors, timed constraints, and conditional logic) each with proven correctness, substantially expanding the range of expressible mission types. Numerical experiments confirm exponential speedups in practice and near-global-optimality on a large benchmark suite.<br>\r\nTime permitting, I will briefly discuss ongoing extensions, including spacetime augmented GCS for dynamic environments, safety-aware planning via conformal prediction sets, and a galactic survey benchmark inspired by space mission planning that stress-tests the framework at scale.<br>\r\n<br>\r\n<br>\r\n<br>\r\n<strong>Biography: </strong>Tyler Summers is an associate professor at the University of Texas at Dallas.

Achieving net-zero transport requires coordinated action across energy carriers, carbon flows and mitigation of other pollutants.

First, using solar-driven CO<sub>2</sub> conversion as an example, I will show how the precise transport of light, heat and fluids enables the coordinated design of materials, devices and systems, maximising solar-to-fuel conversion efficiency. Second, I will explore on-board carbon capture for road and maritime transport, together with distributed carbon-removal networks that use existing vehicles, ventilation systems and transport infrastructure. Third, I will discuss particulate matter generated by brake and tyre wear, illustrating how materials engineering can balance filtration efficiency, pressure drop and energy demand.

In the first part of my talk, I will introduce a method we have developed that allows us to resolve the spatial distribution of stresses in sheared soft-materials, known as Boundary Stress Microscopy. We have applied this technique to suspensions undergoing shear thickening. I will present our results on the existence of clearly defined dynamically localized regions of substantially increased stress that appear intermittently at stresses well above the applied stress. Surprisingly, we find that these spatially distinct and dynamic phases quantitatively account for the observed shear thickening seen in sheared colloidal dispersions (e.g. Oobleck). In the second part of my talk I will discuss our results on the rheology of active matter. Our system is composed of microtubules and kinesin motor proteins that self-assemble to form complexes that propel themselves through the fluid. What results is a dramatic alteration in the measured viscosity. I will provide a simple physical model that fits the rheological response with zero fitting parameters. <br>\r\n<br>\r\n<strong>Biography: </strong>Daniel Blair is a Professor of physics and a co-founding member of the Institute for Soft Matter Synthesis and Metrology I(SM)2 at Georgetown University.

Bimodality is common, but trimodality—that is, the ability to successfully navigate between aerial, aquatic, and terrestrial environments—is relatively rare. Multimodality is also challenging to achieve in engineered devices, vehicles, and robots; however, several animals are capable of regularly (and easily) traversing environmental boundaries. In this talk, we will outline several of the general adaptations that living organisms use to locomote between land, air, and water. We will then present recent work on the biomechanics and fluid dynamics of trimodal aquatic insects. These insects exhibit hybrid walking-swimming gaits when transitioning from land to shallow water; they also leverage surface tension, buoyancy, fluid drag, and aerodynamic forces to take off into flight directly from the water surface. They also display underwater agility, using their legs as paddles to propel themselves rapidly as they seek prey and/or escape from predators. They also have interesting morphological features to enable these transitions, including superhydrophobic wings and hemelytra, as well as dense setae lining the metathoracic legs. These bristle-like features create shape-morphing appendages for efficient swimming, and are also used to lever the insect’s body off the deforming water surface during takeoff. In this talk, we will present data from all three locomotor modes and discuss their implications for both fundamental biology and ecology as well as bioinspired engineering and technology development.<br>\r\n<br>\r\n<br>\r\n<strong>Biography: </strong>Dr. Margaret L.
