The talk is about 2 topics:

1) Generating neutrino mass via fermion kinetic mixing. In this work we show how neutrino masses can be obtained from the radiative fermion mixing of 2 or more dark fermions and what kind of consequences and signatures this scenario can have compared to other similar models of neutrino mass. [arXiv:1807.07988]

2) In this work we demonstrate how Scotogenic neutrino mass generation can be embedded in SU(7) GUT with different possible phenomenology and signatures. In this scenario we have a low energy Pati-Salam like,SU(4)c×SU(2)L×U(1)R, symmetry. We also show how the SU(7) symmetry and subsequent symmetries can be broken down to SM, as well as investigate possible dark symmetries needed for Scotogenic scenario.
