Research Interests
Understanding and controlling condensed-matter phenomena has transformed everyday life — from transistors and magnetic memory to lasers, solar cells, and digital displays — while unexpected discoveries such as superconductivity and topological electronic states continue to challenge established theories of matter. Our group uses atomically thin van der Waals materials as a versatile platform to investigate such open questions and pursue capabilities beyond those of conventional materials. Using light–matter interactions and electrical transport as our primary probes, while harnessing chemistry and atomic-scale engineering to tailor materials, we investigate a broad range of quantum phenomena. For example, we study how excitons could generate single photons for quantum technologies, how magnetism might be switched electrically for energy-efficient memory, and how quantum geometry could enable unconventional approaches to sensing and energy harvesting. Through this interplay of discovery and materials engineering, we seek both a deeper understanding of quantum materials and opportunities to create new technologies.
