About me

Research Interests

My research is focused on the study of functional materials using sychrotron radiation based spectroscopic techniques. My main focus is in on the charge dynamics in hybrid and inorganic perovskite materials using Pump-Probe Time Resolved Photoelectron Spectroscopy (TR-PES), Core-Hole Clock Spectroscopy (CHCS) and Two Photon Photoemission (2PPE). I also have strong activties using Hard X-ray Photoelectron Spectroscopy (HAXPES) and Auger- Photoelectron Coincidence Spectroscopy (APECS).
