Don Siegel is a Professor in the Department of Mechanical Engineering and the Department of Material Science and Engineering. His research targets the discovery, characterization, and understanding of novel materials for energy-related applications. These efforts primarily employ atomic scale modeling to predict thermodynamic properties and kinetics. These data provide the necessary ingredients for identifying performance limiting mechanisms and for the “virtual screening” of candidate compounds having desired properties. Prof. Siegel is currently exploring several varieties of energy storage materials, lightweight structural alloys, and materials suitable for use in carbon capture applications.

Thornton’s research focuses on computational and theoretical investigations of the evolution of microstructures and nanostructures during processing and operation of materials. These investigations facilitate the understanding of the underlying physics of materials and their performance, which will aid us in designing advanced materials with desirable properties and in developing manufacturing processes that would enable their fabrication. The topics include growth and coarsening of precipitates, evolution of morphologically and topologically complex systems, microstructure-based simulations of electrochemical systems such as batteries, and self-assembly of quantum dots and other nanoscale phenomena during heteroepitaxy of semiconductors.  These projects involve advanced computational methods and large-scale simulations performed on high-performance computational platforms, and insights provide a means for material design and optimization.

His research interests lie in the development of numerical methods and models for massively parallel computations of fluid mechanics problems on modern computing architectures, including GPUs. He specifically focuses on high-order accurate finite difference/volume/element and spectral methods desgined for robust, accurate and efficient simulations. With his codes, he investigates the basic physics of multiphase flows, high-speed flows and shock waves, turbulence and mixing, interfacial instabilities, complex fluids and plasmas. Target applications include biomedical engineering, energy, aeronautics and naval engineering.

Time sequence showing turbulent mixing between two fluids of different densities. Vortical structures colored by density highlight how the mixing region grows while the turbulence decays. The results are obtained using direct numerical simulation (DNS), in which all dynamical scales are resolved.

Brian Arbic is a physical oceanographer. His group focuses on global modeling of internal tides and gravity waves, with growing interests in air-sea interactions and modeling of surface tides and their role in Earth System processes over geological time scales.  Other interests include the dynamics and energy budgets of oceanic mesoscale eddies (the oceanic equivalent of atmospheric weather systems), tsunamis, and paleotsunamis. His group uses in-situ and remotely sensed observations, idealized models, and realistic models.  He collaborates widely with scientists in the US and abroad, and his projects include collaborations with scientists at large modeling centers, such as the US Naval Research Laboratory (NRL), NOAA’s Geophysical Fluid Dynamics Laboratory (GFDL), DOE’s Los Alamos National Laboratory (LANL), Europe’s Mercator Modeling Center, and NASA’s Jet Propulsion Laboratory (JPL).  He participates in NASA missions, including the Surface Water Ocean Topography (SWOT) mission, the Sub-Mesoscale Ocean Dynamics Experiment (S-MODE) mission, and the Ocean Surface Topography mission.  Arbic has been a member of the U-M ASC STEM Africa committee since 2012.  He is the principal founder of the Coastal Ocean Environment Summer School in Ghana (https://coessing.org), is the lead on the concept note for “An Ocean Corps for Ocean Science” (https://globaloceancorps.org), and a co-lead on the concept note “EquiSea:  The Ocean Science Fund for All” (https://equisea.org).
