My interests are in materials informatics, density functional theory, machine learning, bayesian inference, and optimal design methods applied to accelerate the search and discovery of novel 2D materials, alloys, ferroic and electronic materials.
A combination of modeling and machine learning has been able to identify the optimal nanostructure for graphene nanoribbons for a thermoelectric to convert heat to electricity. This optimization strategy could be applied to other materials where a desired physical property requires balancing conflicting characteristics.
