Looking deep into the night sky, there are countless stars, myriad shapes of gas clouds, pulsars, supernovae, and galaxies. However, it is now proven that the Universe is mainly filled with what we cannot see; dark energy and dark matter. Astrophysical observation indicates that 68% of the Universe is made up of dark energy, 27% is dark matter, and the rest 5% is ordinary matter. Therefore, probing the dark components of the Universe is the most prominent subject in modern particle physics.

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. The 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 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.
