My research interests

My research is mainly focused on understanding the generation and evolution of primordial perturbations during inflation and in alternatives/extensions to the inflationary paradigm such as bouncing scenario and loop quantum cosmology. My Ph.D. thesis was titled "Computation and characteristics of inflationary three-point functions".

Topics of my interest include:
