Laurence Marks

Laurence Marks Marks is a Professor of Materials Science and Engineering at Northwestern University. He pioneered the use of HREM to study the structure of nanoparticles, the use of direct methods for surfaces with either electron or x-ray diffraction data, in-situ methods for tribology inside electron microscopes, fast methods of obtaining optical and structural measurements from single nanoparticles and most recently a new class of fixed-point algorithms for DFT calculations. His research interests include transmission electron microscopy, density functional theory methods, direct methods with diffraction data, surface science particularly of oxides, tribology, hip replacements, corrosion as well as nanoparticle structure, growth and plasmonic properties. He is PI and primary point of contact for the MURI project.

John Perepezko

John Perepezko Perepezko is a Professor of Materials Science and Engineering at the University of Wisconsin-Madison. He has worked extensively in the analysis and modeling of alloy solidification and microstructure development. This includes the nucleation of phases during interdiffusion and interface reaction in thin-film multilayers. With this understanding he has developed the concept of a kinetic bias. Other work involves multiphase microstructures involve examining high-temperature alloys such as superalloys, titanium aluminide intermetallics and refractory alloys. The examination of phase stability and reaction kinetics during processing provides a basis for the achievement of tailored microstructures and alloy designs to enhance performance in structural applications as demonstrated in advanced Mo-Si-B alloys.

Petra Reinke

Petra Reinke Reinke is an Associate Professor of Materials Science and Engineering at the University of Virginia. Her research interests are in the area of carbon, semiconductor and metal nanostructures which are investigated using surface science methods, such as scanning probe microscopy (STM and AFM) and photoelectron spectroscopy. Nanostructures of interest are clusters, wires or even more complicated networks, and to study their formation and how they interact with corrosive gases, and the relation between their geometric and electronic structure and properties.

James Rondinelli

James Rondinelli Rondinelli is an Assistant Professor of Materials Science and Engineering at Northwestern University. He uses a combination of first-principles electronic structure methods, symmetry analysis and crystal chemistry tools to study the fundamental properties of materials at the atomic scale. His group's main interests are in technologically important energy, electronic, magnetic, and optical materials. Using multiple level so of theory and computational tools, his group disentangles critical structure-property relationships required to design and engineer their performance. A primary focus is on multi-property material optimizations through the identification of new structure-based routes to combine diverse functionalities into artificial materials. This involves working closely with experimental collaborators to realize electronic structure-driven materials discoveries.

John Scully

John Scully Scully is a Professor of Materials Science and Engineering at the Univeristy of Virginia. His primary research interest is to understand the relationships between a material's structure and composition and properties related to environmental degradation. The properties of focused interest and activity are those associated with hydrogen embrittlement, stress corrosion cracking, localized corrosion, and passivity of materials. He has worked extensively on advanced aluminum, magnesium, titanium, ferrous and nickel-based alloys, as well as stainless steels and aluminum-based intermetallic compounds. A secondary engineering objective is development of methodologies for lifetime prediction engineering materials in corrosive environments.

Peter Voorhees

Peter Voorhees Voorhees is a Professor of Materials Science and Engineering at Northwestern University. He is involved in research that employs theory, simulation, and experiment in areas from nanotechnology and energy to four-dimensional microscopy. He has many active projects involving phase field simulations and theory including semiconductor nanowire growth, solid oxide fuel cell materials including three-dimensional structure of the voids and phases in anodes and cathodes. the dynamics of grain growth in materials and experiments on the coarsening of solid-liquid mixtures on the International Space Station and the evolution of morphologically complex two-phase mixtures.
