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.

Beverley J. McKeon
Theodore von Karman Professor of Aeronautics
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.
Specific interests include:
Modeling and control of wall-bounded flows using smart, morphing surfaces. Resolvent analysis as a tool for modeling turbulent, transitional and controlled flows; rigorous, system-level tools for understanding flow physics and design of flow control schemes. Assimilation of experimental data for efficient low-order flow modeling.
Measurement, definition and description of high Reynolds number wall turbulence. Interdisciplinary approaches to experimental flow manipulation for performance enhancement and understanding of fundamental flow physics; application of new materials to flow control.

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.

Professor Owhadi’s research concerns the exploration of interplays between numerical approximation, statistical inference and learning from a game theoretic perspective.

Bren Professor of Computational Biology and Computing and Mathematical Sciences
Professor Patcher is a computational biologist working in genomics. His career began in comparative genomics, and initially was interested in genome alignment, annotation, and the determination of conserved regions using phylogenetic methods. More recently he's become focused on functional genomics, which includes answering questions about the function and interaction of DNA, RNA and protein products. He's particularly interested in applications of high-throughput sequencing to RNA biology. Genomics requires the development of algorithms, statistical methodology and mathematical foundations, and a major part of his research is therefore on methods.
