Colloidal nanocrystals
Shape-controlled synthesis of quantum dots, nanoplatelets, and nanowires with attention to their surfaces and interfaces.
Research
Building materials from the surface outward.
My work connects synthetic control at the nanoscale with light emission, charge transport, and spin-selective behavior.
Halide perovskites
Low-dimensional perovskite emitters for spectrally pure, stable, and polarized light.
Chirality & spin
Ligand-directed chiroptical response and spin selectivity in metal chalcogenide nanocrystals.
Optoelectronic devices
Nanocrystal LEDs and solar cells that connect materials chemistry to measurable device performance.
Current focus
CHINOS
Chiral nanoplatelet assemblies for optoelectronic and spintronic devices.
My MSCA project explores how perovskite nanoplatelets can be organized into anisotropic assemblies—and how that organization can translate into polarized emission and new spin-dependent functionality.
