Our lab’s scientific interests are in experimental particle and astroparticle physics with a focus on the invisible mass component of the universe which includes dark matter and neutrino. Existence of dark matter and massive neutrinos lead to profound consequences for the evolution of the Universe. The two are similar in many ways as they both exist everywhere and interact weakly. The Standard Model of particle physics does not accommodate a suitable dark matter candidate. Therefore the presence of dark matter is a crucial phenomenological evidence for physics Beyond the Standard Model. Our approach to these profound subjects is to probe the particle nature of dark matter through direct detection and to study neutrino physics using state-of-the-art technologies.
