Dennis M. Kochmann

Professor of Aerospace

Professor Kochmann's research combines theoretical, computational, and experimental solid mechanics to study the link between microstructure and macroscopic properties of a variety of engineering materials. One of his areas of research is the simulation of microstructures in crystalline solids (such as metals). In contrast to many current phenomenological theories, Professor Kochmann's research aims at physics-based and hence predictive multiscale models applicable to polycrystal plasticity and twinning. Another of his research areas is the design of novel composite materials with tunable performance, for instance, materials whose stiffness and damping can be tuned by orders of magnitude, reaching viscoelastic stiffness greater than that of a diamond. He designs these materials using a careful composite architecture and utilizing phases with so-called negative-stiffness mechanisms.

Professor McKeon explores new ways to manipulate or control the boundary layer—the thin layer between a material and flowing air—to improve flow characteristics, such as a reduction of drag, noise, and structural loading or expansion of vehicle performance envelopes during travel. The unifying theme to her work is an experimental and theoretical approach at the intersection of fluid mechanics, control, and materials science to investigate fundamental flow questions, address efficiency and performance challenges in aerospace vehicle design, and respond to the energy conservation imperative in novel and efficient ways.

Austin Minnich

Professor of Mechanical Engineering and Applied Physics

Professor Minnich researches the physics and engineering of nanoscale heat transport. Nanostructured materials have novel thermal properties with applications in energy such as for thermoelectric materials, which convert heat directly to electricity. Minnich uses experimental techniques, including ultrafast optical experiments, to study transport at the length and time scales of the energy carriers themselves. These experiments measure properties of the energy carriers that are lost at macroscopic scales, allowing for a more complete understanding of nanoscale transport physics. Minnich also uses these results to design novel materials and thermal devices, such as more efficient thermoelectric materials and devices for thermal energy storage.
