About

The Accelerated Materials Discovery Lab is focused on applying automated and high-throughput methodologies to discover and develop novel materials for extreme environments (high mechanical stresses, temperatures, and radiation fluxes). We utilize procedures derived from ‘self-driving labs’ to guide a microstructural optimization loop through combinatorial synthesis approaches (typically thin film sputtering), microstructural modification by ion irradiation or annealing, and high-throughput characterization, which includes a number of techniques such as X-ray diffraction (XRD), electron microscopy, small-scale mechanical testing, and thermal analysis (ultrafast nanocalorimetry).
