My research interests and work lie at the intersections of the fields of astrophysics, particle physics, nuclear physics and cosmology, in particular concerning neutrinos and weak interactions. My activity covers both theoretical and phenomenological aspects, in relation either with neutrino experiments and astrophysical neutrino observatories, or for the implications of neutrino properties in astrophysics.  

             Recently, I have been mostly working on the neutrino quantum kinetic equations, novel neutrino flavor mechanisms in dense astrophysical environments (core-collapse supernovae, binary neutron star mergers), the influence of strong gravitational fields on neutrinos, non-standard neutrino properties or interactions, the connection of a weakly interacting neutrino gas with other many-body systems, such as atomic nuclei and condensed matter.
