Research

 
I am interested in cosmology and astroparticle physics. It is founded upon the insight that the physics of stars, galaxies, and the Universe,  is in fact crucially related to the physics of its tiniest constituents, i.e., atoms, nuclei, etc. I focus on the physics of neutrinos and dark matter in stars and the early Universe.

They are crucially important for the evolution of stars and galaxies, and come to us from the depths of these faraway and dense parts of the Universe bearing useful information. Studying these particles have already resulted in major discoveries in physics but more excitement is in store! 

I work on the physics of supernova neutrinos, high-energy neutrinos from GRBs, AGNs, etc., as well as the impact of neutrinos in cosmology. Read more here.

Dark Matter is my other main research interest. We now know that the Universe is mostly made of invisible stuff whose presence can be inferred through gravitational effects. It is clear that no known particle can play the role of this dark matter, and discovery of the particle identity of dark matter promises to be a huge breakthrough.

I work on different aspects of dark matter physics, be it possible mechanisms for its production, various ways to identify its particle nature, or its impact on galaxies, etc. You can read more here.
