Dr. Nidhi Pant obtained her PhD in cosmology through a visiting student program at Inter University Center for Astronomy and Astrophysics, India and Jamia Millia Islamia.

Before joining HKUST, she worked as a research associate at The Chinese University of Hong Kong (2021-2022).

She worked as a Claude Leon and SKA postdoctoral fellow at the University of the Western Cape, Cape Town (2013 to 2017) and postdoctoral researcher at Inter University center for Astronomy and Astrophysics(IUCAA) in Pune, India (2013-2017). At IUCAA, she worked with a team and contributed to testing “Isotropy and Statistics of the CMB” for European Space Agency’s Planck mission which mapped the anisotropies in Cosmic Microwave Background(CMB).

Research Area

Dr Pant’s current primary research interest is exploring the potential of Pulsar timing arrays to detect stochastic gravitational wave background and individual sources.

Her research revolved around testing fundamental assumptions in the concordance model of cosmology with cosmic microwave background (CMB) and SKA. She worked on exploring the possibility of isotropy violation in the distribution of matter, and its relation to isotropy-violation in the background radiation.
