Many research groups in our department use advanced scientific computing and molecular simulation as tools for elucidating chemical, physical and biological fundamentals. For example, we are examining the formation and fate of nanoparticles in the environment, chemical reactions occurring on catalyst surfaces, cellular signaling, polymer rheology, low temperature plasmas and nano-scale self assembly of particles with different geometries.
Professor Andrew Allman and his research team focus on the development of theory and algorithms which support efficient and optimal decision making (i.e. design, operation and control) for chemical, energy, and biological systems. In particular, our team seeks to develop tools which exploit the structure inherent in such systems in order to quickly solve traditional model-based optimization problems, as well as to identify low-dimensional data subspaces which are most informative towards decision making.
Professor Sharon Glotzer and her research group use computer simulation to discover the fundamental principles of how nanoscale building blocks can self-assemble and how that assembly process can be guided to engineer new materials. Her team develops the theory and molecular simulation tools to understand self-assembling, self-sensing, and self-regulating materials. They also model supercooled liquids, glasses, and crystallization processes.
Computational modeling of catalysts and materials, and making use of its synergy with experiments, facilitates the process to design new systems since it provides a valuable way to test hypotheses and understand design criteria. Our research team focuses on understanding catalytic systems and advanced materials for use in sustainable chemical production, pollution abatement, and energy generation. To accomplish these goals we utilize and develop various computational tools such as first-principles modeling (e.g., density-functional theory, wave-function based methods, and ab initio thermodynamics), molecular simulation, and data analytics algorithms (e.g., statistical learning and data mining).
Professor Mark Kushner and his group develop computationally investigate the fundamental transport and kinetic properties of low temperature plasmas (partially ionized gases), plasma chemistry and plasma surface interactions and their application to society benefiting technologies. Current projects include plasma fabrication of advanced materials for nano-electronics, plasma medicine (use of plasmas for human healthcare), macro- and micro-plasmas as photonic sources, plasmas in liquids, plasma treatment of porous polymeric membranes, and plasma aided combustion for energy efficient transport systems.
Professor Ronald Larson’s simulation work spans the rheology of polymers, surfactant microstructures, polymer/drug interactions and reconfigurable colloids.
Professor Nina Lin and her group study biological switching, the symbiotic relationships among communities of microbes and engineering microbial communities process chemicals such as biofuels. Her team uses a combination of experiments and computer modeling.
Professor Jennifer Linderman and her group develop computer models of cell signaling. In addition to simulating cell signaling mechanisms, the group is modeling the signaling events that lead to metastasis in breast cancer and the interplay between immune cells and bacteria in tuberculosis infections.
The central objective of Professor Suljo Linic’s lab is the development of predictive theories of surface chemistry related to heterogeneous catalysis, electrocatalysis and photocatalysis. Through experiments and theoretical studies, lab members are currently working on a number of projects that aim to address various issues in the fields of energy and environment, functional nanomaterials, industrially-important reactions and fundamental heterogeneous catalysis.
Professor Greg Thurber and his research group study molecules used to image diseased tissue such as tumors, Alzheimer’s plaques and arterial plaques through a combination of experiment and modeling. The same features that allow imaging molecules to target particular tissues can also be turned to targeted drug delivery. With a fundamental understanding of how molecules distribute in the body, the team can design better molecules for imaging and therapies.
Professor Violi and her research group use computer simulations to discover the fundamental principles that drive the interactions of nanomaterials and biological systems and how to engineer new materials to guide these interactions. Examples of applications include the development of models to predict the formation of nanomaterials, their assembly and growth in reactive environments in various scenarios, plasma conditions to engineer materials for energy, biomedical application and environment remediation.
Professor Robert Ziff and his colleagues use computer simulation and mathematical modeling to study a variety of problems of interest to fields of chemical engineering, mathematics, and physics. The modeling and simulation work includes several numerical algorithms to obtain precise critical connectivity thresholds for two and three-dimensional systems through the percolation model. Ziff and his colleagues have also developed a kinetic Monte Carlo technique that allows reaction dynamics to be studied efficiently, including the kinetic phase transitions that occur in such systems.
