I will give an overview of sterile neutrino physics in the early universe and in cosmology, especially as regards dark matter. This will include a discussion of production mechanisms, relic densities, the relationship of these to lepton and baryon numbers, and associated high energy scale physics issues. I will also discuss the status of X-ray observational constraints on sterile neutrino and...

I discuss the status of non-standard neutrino interactions, especially their impact on next-generation neutrino oscillation experiments.

New physics beyond the Standard Model could appear at long baseline oscillation experiments as non-standard interactions (NSI) between neutrinos and matter. If so, determination of the CP-violating phase $\delta_{13}$ is ambiguous due to interference with additional complex phases. I'll present my work using both numerical solutions and a perturbative approach to study oscillation...

A good fraction of the heavier nuclei were formed in the rapid neutron capture (r-process) nucleosynthesis scenario. Although an astrophysical site of the r-process is not yet identified, one expects such sites to be associated with explosive phenomena since a large number of interactions are required to take place during a rather short time interval. Candidate sites include core-collapse...

In dense astrophysical environments, the evolution of neutrino flavor is non-linear which can lead to many interesting phenomena. However, this non-linear evolution of neutrino flavor also called the "collective neutrino oscillations" is only beginning to be understood, especially in conjunction with collisions. I will discuss the effect of neutrino back-scattering in the interior of a...

Observational constraints permit a cosmic lepton asymmetry that is orders of magnitude larger than its baryonic counterpart, a possibility of great relevance for leptogenesis, sterile neutrino dark matter, and the flavor evolution of Standard Model neutrinos. It is this last connection that we focus on here: the flavor states of neutrinos in the early universe are coupled to each other,...
