Research Interests: Cosmology, High Energy Physics
Professor Gaurav Goswami is an Assistant Professor at the Division of Mathematical and Physical Sciences, School of Arts and Sciences, Ahmedabad University.
Professor Goswami is primarily a theoretical cosmologist i.e. the primary focus of his research is at the interface of cosmology (which is the scientific study of the origin and evolution of the entire Universe) and fundamental physics (which is the scientific study of the most elementary building blocks of nature).
In addition to this, Professor Goswami’s broader interest lies in carefully understanding the subtler aspects of the very process by which facts are established in natural sciences, other academic disciplines and beyond.
Professor Goswami received a Bachelor of Engineering degree in Chemical Engineering, a Masters in Physics and PhD in Physics from Inter-University Centre for Astronomy and Astrophysics, Pune. During his PhD, Professor Goswami focussed on (a) understanding the evolution of cosmological perturbations in the early universe, and, (b) using the observations of Cosmic Microwave Background to understand the statistical properties of primordial metric perturbations in the early Universe. Between 2013 and 2015, Professor Goswami was a Postdoctoral Fellow at Theoretical Physics Division, Physical Research Laboratory, Ahmedabad where he worked on various issues at the interface of particle physics and cosmology.
From 2015 to 2021, Professor Goswami served as a faculty member at School of Engineering and Applied Science, Ahmedabad University.
Professor Goswami's work is closely related to the following academic disciplines: cosmology, gravitation, elementary particle physics/high energy physics, astrophysics/astro-particle physics, theoretical physics / fundamental physics.
