Current projects

The main focus of my research lies on Charge Transfer Dynamics at Interfaces, particularly heterogeneous electron transfer from organic molecules to semiconductor and metal substrate, and Ultrafast Dynamics in Nanomaterials, e.g. exciton transport and recombination dynamics in semiconductor nanostructures.

The techniques I am using include Femtosecond Laser Spectroscopy, particularly

·        Time-Resolved Two-Photon Photoelectron Spectroscopy

·        Transient Absorption Spectroscopy, and

·        Time Resolved Fluorescents Spectroscopy and Microscopy
