Materials and Computational Chemistry. Research in this area (Adelstein) seeks to understand and improve materials for electrochemical technologies, with a focus on Li-ion batteries. We study atomic-scale processes, such as diffusion, in battery materials, using first-principles (quantum mechanics) simulations. Computational and Structural Biochemistry. Molecular dynamics simulations are used to study conformational dynamics of macromolecular structures including proteins, protein/DNA compexes, and DNA repair machinery. Topics of research will include computational studies of carcinogen modified bases and understanding the role of structural features in human DNA repair and recognition (Guliaev).

Research focuses on areas related to renewable energy and environmental remediation. Electrochemistry methods are used to examine charge transfer at the interface of electrodes and molecules in (photo) electrocatalytic anode reactions (Qiu); structural characterization methods include scanning electron and atomic force microscopy (SEM and AFM). Transition metal oxide and chalcogenide thin films are synthesized and characterized (SEM, AFM, XRD, conductivity, etc.) to prepare robust charge transport layers, photocatalysts for environmental remediation, and photoelectrocatalysts for water splitting (Ichimura). Lithium ion battery materials are studied using density functional theory (DFT) to inform the design and efficacy of solid state electrolytes (Adelstein).
