Current research interests
More about my lab at the group website HERE
My group studies the exciton transport dynamics and growth/ morphology of organic and composite nanomaterials via experiments and numerical investigations. Photo-induced magnetic responses, photo-catalysis, optical-vortex pattern formation, and self-assembly are my primary interests.
This research aids the design and development of next-generation solar cells, organic electronics, and energy-harvesting technologies, and is moreover applicable to the "bottom-up" synthesis of nanomaterials. Our studies are also relevant to the soft-matter nonequilibrium nucleation dynamics observed in biology, chemistry, and medicine.
