Computational Materials Design Laboratory: Rees B. Rankin Research Group

Mission

The Computational Materials Design Laboratory (CMDL) is a research group of 'in silico' experts working to advance rational materials design in areas of heterogeneous interfacial phenomena. Our expertise specifically is in the use of Density Functional Theory (DFT) to characterize the surface properties of catalysts, sorbents, self-assembled bio-relevant molecules on metal surfaces, and organic nanoelectronic materials, where we seek to make fundamental and transformative discoveries via the 'descriptor' approach.

Research Overview

Our research uses DFT (Density Functional Theory) as implemented in the VASP plane-wave code and further implemented in the Materials Design 'MedeA' interface. This is a GUI-based tool that allows our students (graduate and/or undergraduate) to begin doing high-level quantum-mechanics based materials simulations with zero prior coding experience. Students begin work from day one in our group.

The Computational Materials Discovery research group focuses our efforts to accelerate progress towards rational materials design (RMD) via in silico techniques to create predictive design rules for heterogeneous interfacial phenomena. Specifically, we focus on solid material surfaces and their interactions with small gas or liquid molecules for applications in catalysis, electrochemistry, nano-electronics, biosensing and bioseparations, and more. Our research is conducted with the aim of creating a more energy-efficient, materials-sustainable future through fundamental transformations in technologies related to the above-mentioned applications.
