I am an astrophysicist specialized in bridging theoretical models of dark matter with observational frameworks, particularly with gravitational wave observations.
My published work so far deals with primordial black hole models as dark matter, exploring how refinements to these models affect projections to their abundance constraints from future observations. I am also interested in dark matter models in general, whether it be particle dark matter, massive compact halo objects, or modifications to gravity at extragalactic scales.
