I obtained my masters degree in Physics at University of Hyderabad (stood All India 2nd rank in the entrance examination), India.

After that, i worked for 6 months in the Fog Vision project funded by Indian Railways at Indian Institute of Technology, IIT Kanpur.

My doctoral thesis was in Physics discipline and title of the thesis: Ion channeling in Ultra-thin crystals. (An experimental study of early evolution of energetic particles in crystals).

After that, i explored the applications of X-ray Absorption spectroscopy and real-time mass-spectroscopy for energy, environment and health sectors at Nanoscience and Nanotechnology center, SINBERISE, NUS-Singapore.


  • In-situ ion beam spectroscopy of catalytic surfaces for Electro and photo chemical devices.
  • Rapid screening of best alloy compositions using combinatorial libraries.
  • Sub-nm depth resolution of elemental depth profiles using high-resolution RBS spectrometry (MEIS).
  • Sub-micron spatial resolution channeling contrast microscopy using MeV ion RBS-Channeling.
  • Making sub-Å focused ion beams using single crystal as a focusing lens.
  • An experimental way to deduce the fundamental inter-atomic potentials, energy losses.
  • Fabrication of nanostructures by direct writing of low energy ion beams (sub-5 nm structures using HIM), and MeV focused ions beams (MeV Proton beam writing for sub surface structures).
  • Electronic and magnetic properties of metal oxides.
  • Real time quantification of ppt level gaseous molecules in ambient air:
    • : Artificial photosynthesis (Photo, electro chemical reduction of CO2).
    • Energy devices: Failure analysis of organic devices, perovskite solar cells.
    • : Non-invasive identification of diseases including Cancer, Diabetes.
