My research is aimed at furthering our understanding of early universe physics through the impact this physics may have on observable quantities.
I am particularly interested in the dynamics of quantum fields in the early universe with a focus on signatures they may impart on cosmological and astrophysical observables. In this line of research, some of the exciting phenomena that I have explored include: primordial gravitational waves from inflation, primordial black holes as dark matter, dynamics of (p)reheating and non-thermal dark matter candidates.
Currently I am interested in the dynamics of axion-like fields (ALPs) in the context of:
- scalar dark matter paradigm and its gravitational wave signatures at terrestrial and spatial interferometers.
- cosmological inflation including their observational implications at CMB and sub-CMB scales.
