My current research focuses primarily on investigating new physics through flavor and neutrino physics. Flavor physics offers a promising avenue to investigate physics beyond the Standard Model through precise measurements capable of detecting the virtual production of new particles within quantum loops. The ongoing experiments such as LHCb at CERN and Belle II in Japan have already yielded intriguing indications of physics beyond the Standard Model. These experiments hold significant potential to translate existing signatures into potential discoveries of new physics, thereby unveiling the deepest secrets of the universe. Beyond deciphering these observed deviations, my research endeavors to bridge the realms of flavor physics with the cosmic landscape of astroparticle physics and cosmology, painting a vivid picture of the universe's hidden truths. We accomplish this by forging myriad connections between key observables in particle physics, astroparticle physics, astrophysics, and cosmology. Among the pivotal research themes of our group are:

  1. CP violation in flavor and neutrino physics.
  2. EM properties of neutrinos: This is one of the most important tools for probing new physics. Owing to non-zero mass, neutrinos possess an extremely tiny magnetic moment which can be enhanced in a number of new physics models. This can have intriguing implications for currently operative and planned neutrino telescopes.
  3. Cosmic Magnetism: This includes exploring implications of primordial as well as intergalactic magnetic fields.
  4. Cosmic neutrino background
  5. Compact stars as laboratories to probe new physics
  6. Neutrino-dark matter interactions
  7. Quantum decoherence

I'm also exploring the intersection of particle physics and quantum information theory, focusing on quantum correlations. Recent advancements in high-energy physics experiments, like meson factories and long baseline neutrino experiments, open up new avenues for studying quantum mechanics in subatomic systems. Unlike optical or electronic systems traditionally used for studying quantum mechanics foundations, high-energy experiments offer higher detection efficiencies, providing an alternative platform for testing quantum principles.
