Supriya Pan
Assistant Professor
About-
Welcome to my profile page!
I am working as an Assistant Professor in this Department since August 08, 2018. My broad research area is Cosmology. Currently, I am investigating various cosmological scenarios including dark energy, modified gravity, matter creation etc, using present and future astronomical probes. One of my key research areas is to understand the origin of the cosmological tensions! In 2021, I wrote an invited review article for Classical and Quantum Gravity on the Hubble constant tension. Recently, I wrote another invited review article for Physics Reports on the cosmological singularities.

Biography+
Here is my academic trajectory! I entered the Department of Mathematics, Jadavpur University (JU) in 2006 for my undergraduate studies and finally left with a PhD degree in Science (Cosmology) in December 2015. During my PhD, I worked on the late-time accelerating expansion of our universe.
After my PhD, I joined the Department of Physical Sciences (DPS), Indian Institute of Science Education and Research Kolkata (IISER-K) as a Post-Doctoral Fellow. Initially, I worked as an NBHM (National Board for Higher Mathematics) Post-Doctoral Fellow for 3 months and then I left the NBHM position and joined as a National Post-Doctoral Fellow. While working there, I was selected for the post of an Assistant Professor of Mathematics by WBCSC. I joined an undergraduate college affiliated to the University of Gour Banga in March 2017 and I worked there for 1 year and 4 months (approximately). Finally, on 8th August, 2018, I joined Presidency University as an Assistant Professor of Mathematics!
Research / Administrative Experience+
I mainly work on the late-time accelerated expansion of the universe (The 2011 Nobel Prize in Physics was awarded for this discovery), a specific area of cosmology where we need to introduce some ‘exotic’ (does not sound to be natural) kind of fluids, namely Dark-Energy in the context of Einstein’s General theory of Relativity or one may either try to modify the General Relativity or introduce some new gravitational theory leading to extra geometrical terms which could drive the observed accelerating expansion of the universe. Initially, I started wokring on the theoretical aspects of the dark energy models, their possible interactions with other cosmic fluids, for instance the dark matter, but around the end of my doctoral thesis, I started investigating the observational constraints of those models. When I joined the Post-Doctoral position, I continued working on the observational analyses of the cosmological models taking different cosmological probes from several astronomical sources. Throughout that period, I have collaborated with many renowned researchers of gravity and cosmology (a complete list is given in my CV) all over the world.
Apart from that, very recently, with my collaborators, I have started working on the gravitational wave data analyses to constrain the parameter space of various cosmological models.
My current research interests are:
Interacting and non-interacting dark energy models; Hubble Constant Tension; Massive neutrinos in the universe sector; Modified gravity theories; Matter creation by the gravitational field; Gravitational waves.
