Allison Steiner is an Associate Professor of Climate and Space Sciences and Engineering. Her research focus is on the relationship between the atmosphere and the terrestrial biosphere to help understand the bigger question: how will the Earth respond to climate change? Her research integrates gas and particulate matter, including anthropogenic aerosols and natural aerosols such as pollen, into high-resolution models. She and her research group then compare these results with observations to develop a comprehensive understanding of regional scale climate and atmospheric chemistry.

Professor Qi’s research fields are investigations of the mechanical and chemical properties of materials by applying theoretical and computational tools, including first-principles calculations, atomistic simulations and multiscale modeling. His major research interests are quantitative understanding of the intrinsic electronic/atomistic mechanisms for the mechanical deformation, phase transformation and chemical degradation (corrosion/oxidation) of advanced alloys and other structural/functional materials. Currently he is focusing on the studies of deformation defects and interfaces in materials under extreme conditions, such as high stress and/or chemically active environment, where the materials behaviors and properties can be dramatically different than those predicted by classical theories and models. He is also developing the numerical methods to integrate these electronic/atomistic results with large-scale simulations and experimental characterizations in order to design materials with improved mechanical performances and chemical stabilities.

A Jahn-Teller distortion signifies the onset of the shear instability for a body-centered-cubic crystal placed under tension. The symmetry breaking correlates with the intrinsic ductility of the material, and the strain at which it appears can be controlled by alloying.

Santiago Schnell’s lab combines chemical kinetics, molecular modeling, biochemical measurements and computational modeling to build a comprehensive understanding of proteostasis and protein forlding diseases. They also investigate other complex physiological systems comprising many interacting components, where modeling and theory may aid in the identification of the key mechanisms underlying the behavior of the system as a whole.

Professor Becker leads an interdisciplinary group to understand problems in surface geochemistry and computational mineralogy, thus there are research opportunities in fields ranging from experimental approaches and computational modeling of actinide geochemistry (U immobilization in the environment, actinide-containing solids under extreme pressure, temperature, and radiation, U/Np/Pu redox processes) to carbonate biomineralization. Other research includes calculating redox processes (including resolving individual kinetic barriers that control kinetics) carbonate and phosphate biomineralization (from environmental applications to processes on teeth). As a part of Mineralogy and Materials Science Research Group, Becker’s group  interacts with Radiation Effects and Radioactive Waste Management group, Michigan Geomicrobiology group, Electron Microbeam Analysis Laboratory (EMAL) and Mineral Physics group.

High power laser plasma interactions are interesting for applications such as the generation of energetic, directional electron, photon, ion and neutron beams or inertial fusion energy. Because of the strong electric and magnetic fields that lead to extremely far from equilibrium distributions, describing realistic high power laser interactions with plasma typically requires codes using a fully kinetic description. Professor Thomas’ research involves collisional plasma simulation using Vlasov-Fokker-Planck codes, including implicit methods using Krylov solvers for heat transport problems relating to inertial fusion energy. He is also interested in plasma simulation using particle-in-cell methods, including coupling the plasma code to very energetic photons using a Monte-Carlo method, for ultra intense short pulse laser interactions in radiation dominated regimes.

Dr. Toth works on algorithm and code development for space and plasma physics simulations. He has a leading role in the development of the Space Weather Modeling Framework (SWMF) that can couple and execute about a dozen different space physics models modeling domains from the surface of the Sun to the upper atmosphere of the Earth. He is one of the main developers of the BATS-R-US code, a multi-physics and multi-application magnetohydrodynamics code using block-adaptive grids. He is collaborating with many colleagues and students using the SWMF and BATSRUS for a wide range of applications: solar corona, coronal mass ejections, magnetic storms, comets, moons (Titan, Enceladus), planetary magnetospheres (Earth, Venus, Mars, Jupiter, Saturn), interaction of moons with their plasma environment (Titan, Enceladus), interaction of comets with the solar wind, outer heliosphere interaction with the inter-stellar material, etc. The SWMF is used by the Community Coordinated Modeling Center (CCMC) at NASA Goddard for research as well as real-time forecasting of space weather. Dr. Toth was also the software architect for the Center for Radiative Shock Hydrodynamics (CRASH). This DoE funded center worked on modeling radiative shocks created by high energy lasers and the uncertainty quantification of the model results. He has designed and implemented of the Versatile Advection Code, a general purpose publicly available hydrodynamics and MHD code. VAC has been used by hundreds of researchers around the world to simulate various hydrodynamic and MHD problems.

Professor Hartmann studies the processes by which cold clouds of gas and dust fragment and then collapse, forming stars and a surrounding rotating disk; and the evolution of disks which ultimately can form planets. Because protostellar clouds form in complex, highly structured and turbulent gas, time-dependent (magneto)hydrodynamics is required to follow fragmentation and collapse to stars and disks.  Similarly, the evolution of planet-forming disks involves both gravitational and magnetic turbulence. Simulations of cloud and disk evolution over the necessary timescales (105 to 106 years) with reasonable resolution demands extensive parallel processing.
