Wonders About Mysteries of the Universe

I am currently a postdoctoral researcher at the Institute for Astronomy (
IfA), University of Edinburgh, UK. I am primarily working with John Peacock. I obtained my PhD degree from Carnegie Mellon University (CMU) in 2016 working on Large Scale Structure of the Universe with Shirley Ho. Before joining the graduate school, I was a naive undergraduate student at Indian Institute of Science Education and Research (IISER) Pune, India. Outside work, I enjoy cooking and pondering about society.

I am an astrophysicist working on two broad aspects of the universe. On one side I am interested in the small scale non-linear physics,  in particular questions of galaxy formation and evolution especially focusing on the connection between galaxy properties and host dark matter halos including AGN activity. This has the potential to unveil the true physical nature of what is called "Dark matter".
On the other side, I am interested is cosmologically large scale, working on galaxy redshift survey to probe "Dark energy" and general relativity. I have focused on interpreting and extracting information based on galaxy dynamics perceived by a telescope. I have studied various dynamical and environmental effects on the galaxy spectrum and how those can help us make a more precise measurement of the content of the universe with novel tests of general relativity. This involves the understanding of cosmological theory, analyzing complex and large data and searching best fit parameter of the models with high-dimensional parameter space. I normally use C++ and Fortran for all my back-end computationally intensive work and python for front-end. I can't imagine working without the power of numpy.

You can find a list of my publication on arXiv and ADS.
