Expertise

  • charge carrier transport, chirality in low dimensional materials.
  • pump-probe ultrafast spectroscopy and microscopy, single nanostructure optical microscopy, low temperature photophysics. 

Research Activities

My research focuses on the investigation of light-matter interactions in low dimensional semiconductors and related heterostructures. These include 2D van der Waals nanomaterials, colloidal quantum dots and perovskites and related heterostructures made of such nanomaterials. I am particlarly interested interfacial carrier transport and spin selective carrier transport in heterostroctures for quantum information processing.  I also manage and maintain the Advanced Optical Facility of the CFN , having a strong interest in the development of novel ultrafast methods for materials science in general.
