Personal Statement:

My research is focused on using first-principles computations to design novel materials and heterosystems to address a wide range of globally important issues, from energy sustainability and environmental protection to advances in medicine at the nano-bio interface and next-generation magneto-electronic technologies. Trends in system complexity and component scale in each of these areas are pushing the role of interfaces — the boundaries between different materials or phases — to the forefront in an increasing number of practical applications. It is therefore essential to develop a fundamental understanding of interfaces and their effects on functionality. Additionally, while only a small fraction of the immense phase space spanned by interfaces has been explored at the atomic scale, it has already proven rich with possibilities for the discovery of novel physics and chemistry, as well as the potential for providing creative new tools for tailoring materials behavior from the nanoscale all the way up to the macroscale.
