Our research explores how collective material properties arise from the hierarchical assembly of nanomaterials, modulating the self-assemblies at different structural levels (intermolecular, interlayer etc.) to create buildable long-range interactions. We will design nanomaterials with unconventional excitonic behaviors that cannot be entirely described by either Wannier-Mott or Frenkel exciton models. Such materials include organic dye aggregates, layered hybrid perovskites and perovskite heterostructures, and nanocrystal assemblies. We will use state-of-the-art correlative and in-situ experimental techniques to enable a physically and chemically informed approach towards materials discovery. The materials we develop will have broad applications relating to energy & sustainability, and next generation quantum technologies.
Our research is highly interdisciplinary but serves the common goal of expanding the boundaries of fundamental knowledge while building strong collaborations. Trainees who join our lab will gain expertise in material syntheses and fabrications, spectroscopy, (optical and electron) microscopies, crystallography, custom-instrumentation and large data analysis while developing a strong foundation in quantum chemistry, thermodynamics, supramolecular chemistry, and solid-state chemistry. Interested students and postdocs, please email the PI with your CV and research interests.
