We are interested in understanding the excitonic energy dynamics following photon absorption. Excitons play an essential role for energy transport in natural processes such as photosynthesis as well as in nanostructured optoelectronic devices. Understanding and manipulating the exciton transport dynamics in such systems can not only enhance the device performance, but also lead to the development of next-generation technologies for applications beyond energy conversion.
The research utilizes advanced optical spectroscopy techniques (near-field as well as far-field) to create spatiotemporal maps of exciton populations. Research is also dedicated in developing new techniques to understand the energy dynamics at nanoscale. Material systems of interest include 2D materials, molecular solids and organic-inorganic hybrid interfaces.
