Research Interests

My research is focused on novel solid-state material systems and their properties, with emphasis on the discovery and understanding of complex inorganic phases for energy conversion and quantum technologies. For much of my work, I draw upon contemporary “first-principles” density functional theory and data-driven approaches (such as machine learning). My group is working on several research topics including the incorporation of physical principles in deep learning architectures for solid-state materials, defect spin qubits in two-dimensional materials for quantum computing, discovering exotic topological states in 2D materials and their heterojunctions, and understanding the catalytic performance of nanostructured materials. A major theme of my group’s work is to devise computational methods and data-driven tools that exploit connections between these disparate materials classes and phenomena to design new materials for energy and quantum applications and understand novel quantum phenomena at the frontiers of physics, materials science, and chemistry.
