1) Neutrino Masses and Mixings, Leptogenesis: Neutrinos are weakly-interacting particles, which are passing through our body in billions in a second. Neutrinos are found to have a tiny amount of mass (about one-millionth of that of an electron), which might reflect an interesting origin. They come in different flavors and oscillate among them as they travel. Right-handed neutrinos might be the key for the existence of ordinary matter in the universe throught the so-called Leptogenesis. Sterile neutrinos might be also a viable condidate for dark matter. Here is a recent talk on the subject: An SO(10) GUT Model for Neutrino Masses and Mixing Angle Theta_13 2) Quantum Chromodynamics and Physics of Strong Interactions: The strong force binds together the quarks and gluons to form protons and neutrons---the main constituents of atomic nuclei. The strong interactions account for the bulk of the mass of ordinary matter and are responsible for formation of the basic elements. Here are a couple of my recent talks on the subject: Quantum Phase-Space Tomography of Quarks in the Proton Mass of the hadron
