MEAM Seminar: “Control of Turbulent Wall Shear Flows and the Potential for ‘Designer Turbulence'”

The financial and environmental cost of turbulence is staggering: manage to quell turbulence in the thin boundary layers on the surface of a commercial airliner and you could almost halve the total aerodynamic drag, dramatically cutting fuel burn, emissions and cost of operation. Yet systems-level tools to model scale interactions or control turbulence remain relatively […]

MEAM Ph.D. Thesis Defense: “Reactive Planning with Legged Robots in Unknown Environments”

Unlike the problem of safe task and motion planning in a completely known environment, the setting where the obstacles in a robot’s workspace are not initially known and are incrementally revealed online has so far received little theoretical interest, with existing algorithms usually demanding constant deliberative replanning in the presence of unanticipated conditions. Moreover, even […]

MEAM Seminar: “Engineering Interfaces To Improve The Thermal Performance of Wide Bandgap Semiconductors”

Wide bandgap electronics are currently under development due to their potential to create some of the most advanced RF and power electronics in the world. A key concern in their development is the control of the junction temperature during operation which is impacted by the internal device thermal resistance. To address this concern, we will […]

MEAM Seminar: “Target: COVID-19”

Until such a time when the world’s population has achieved herd immunity either through vaccination against or exposure to the SARS-Cov-2 virus, the most effective means for controlling the COVID-19 (and any other) pandemic is frequent testing and resulting preventive measures that reduce the rate of viral transmission. This talk provides a bird’s-eye view of […]

BE/MEAM Seminar: “Microbes in Biomechanics” (Christopher J. Hernandez)

This event will be held virtually on Zoom – check email for link or contact The idea that mechanical stresses influence the growth and form of organs and organisms originated in the 1800s and is the basis for the modern study of biomechanics and mechanobiology. Biomechanics and mechanobiology are well studied in eukaryotic systems, […]

MEAM Seminar: “Modeling the Behavior of Shape Memory Alloy Structures”

I will present recent work on the modeling of the structural response of shape memory alloy tubes, bars, and beams. We have developed a new constitutive model that captures pseudoelastic transformation induced recoverable deformation in SMAs including the strong asymmetries in the tensile and compressive responses. Instead of introducing multiple conditions for forward phase transformation, […]

MEAM Seminar: “Wave Engineering: From Geometry to Fragility”

The elastic properties of materials are determined by a few material constants such as the Young’s modulus. Using super-structures one can effectively change these “constants”. In this way we obtain functionalities such as wave-guiding, acoustic lensing or programmable failure. I will show how topological band theory, known from the description of electrons in solids, provides […]

MEAM Ph.D. Thesis Defense: “Structural and Mechanical Responses to Intermittent Parathyroid Hormone Treatment, Discontinuation, and Cyclic Administration Regimens”

Bone mineral density rapidly decreases upon withdrawal from intermittent parathyroid hormone (PTH) treatment despite its potent effect of promoting bone formation. To better understand this adverse phenomenon, this study first aimed to investigate the phenotype of PTH withdrawal in both intact and estrogen-deficient rat model by using a well-designed experiment combined with innovative longitudinal imaging […]

MEAM Seminar: “Bridging Physical Models and Observational Data with Physics-informed Deep Learning”

Physical models of many natural and engineered systems are, at best, only partially known; a common setting under which classical analytical or computational tools inevitably face challenges and introduce many sources of uncertainty. Therefore, observational data plays a crucial role, yet our ability to collect them far outpaces our ability to sensibly assimilate it, let […]

MEAM Seminar: “’Smart’ Biodegradable Polymer at Nano and Micro Scales for Medical Applications”

The ability to transform medical polymers, commonly used for resorbable surgical sutures, into desired 3D forms/shapes/structures at nano and micro scales with “smart” functions, while sustaining the materials’ excellent biocompatibility and biodegradability, provides significant applications in different biomedical fields, ranging from tissue engineering and controlled drug/vaccine delivery to medical devices. Here, I will present our […]
