I am a Postdoctoral researcher in the Astroparticle Physics group of the Department of Physics and Electrical Engineering. I work in the development of an all-sky field-of-view detector array ALTO for very-high-energy gamma-ray astronomy in the Southern hemisphere. I am mainly involved in the design study and Monte-Carlo simulation of the experiment.

I have worked both in theory and experiment related to cosmic rays and high-energy gamma rays. In theory, I have worked extensively on the propagation of Galactic cosmic rays, and studied various problems in our understanding of these particles as recently revealed by data from new generation experiments. I have also worked on understanding the Galactic diffuse gamma-ray emission and the origin of gamma rays from the Fermi Bubbles.

In experiment, I have been involved in gamma-ray astronomy with the TACTIC and MACE Cherenkov telescopes in India. I contributed mainly in data analysis for TACTIC and in Monte-Carlo simulation for MACE. I have also been involved in cosmic-ray measurements with the LOFAR radio telescope in the Netherlands. My main contribution to the LOFAR cosmic-ray project is the development of the LORA scintillator array which is used as a trigger to register air showers with the radio antennas.
