I give a theoretical overview of some basic properties of massive neutrinos
in these lectures. Particular attention is paid to the origin of neutrino
masses, the pattern of lepton flavor mixing, the feature of leptonic CP
violation and the electromagnetic properties of massive neutrinos. I highlight
the TeV seesaw mechanisms as a possible bridge between neutrino physics and
collider physics in the era characterized by the Large Hadron Collider.Comment: 41 pages, contribution to the 1st Asia-Europe-Pacific School of
