About

Dr Malhotra obtained his PhD at the University of New South Wales Sydney, supervised by Dr Emanuela Dimastrogiovanni.

Career Highlights

Research

He is interested in several aspects of Cosmology, particularly focusing on Stochastic Gravitational Wave Backgrounds (theory and detection) and data analysis techniques applied to Cosmology. At Swansea, Dr Malhotra works with Professor Gianmassimo Tasinato, Dr Ivonne Zavala and other members of the Cosmology group.
