SEMBLANZA

I have completed my Bachelors degree (in year 2005) in Physics from Delhi University, New Delhi, India and Master degree (in year 2007) in Theoretical Physics from Jamia Millia Islamia, New Delhi, India . I have obtained my Ph.D in Cosmology (in year 2013) from Centre for Thoeritical Physics, Jamia Millia Islamia, New Delhi while financed by a Senior Research Fellowship fromCouncil of Scientific & Industrial Research (CSIR), India under the supervision of Prof. Anjan Ananda Sen. My Ph.D. thesis title is: Issues of Accelerating Universe in Particle Physics and Cosmology. After finishing my Ph.D. I have worked as a Post Doctoral Fellow in Observatorio Nacional, Coordenacao de Astronomia e Astrofisica-COA,Rio de Janeiro, Brasil with Prof. Alcaniz Jailson.

My research has been mainly focused on understanding two phases of accelerating expansion predicted in the history of our Universe (one at the very early epoch associated with the very high energy scales, termed as “Inflation” and another at a later epoch with much lower energy scale (commonly refer to dark energy) by various observations; mainly Cosmic Microwave Background Radiation (CMBR), the baryon acoustic oscillations (BAO), distance-redshift relation measurement from type Ia Supernovae and the observation of matter distribution over very large length scales from galaxy redshift surveys. I have been involved in both theoretical modelling as well as constraining the proposed models for both cases of accelerated expansions using the available observational data sets. A major portion of my current research is focused towards understanding the effects of the dark energy or modified gravity theories on the large scale structures (LSS) through the halo mass functions, the cluster number density and the cluster number counts.

Currently, I am trying to implement the alternative cosmological models in a N-body dark matter simulation to generate mock catalogues of observables for such alternative cosmologies, which will help us to study the evolution history of LSS in our universe and it will also help us to identify the imprint of such cosmologies on LSS. Later on, we will be using the available data sets from SDSS-IV and also from future galaxy surveys like DESI in order to constrain these alternative cosmological models.
