Wonders About Mysteries of the Universe


I am currently a postdoctoral researcher at 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 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 a cosmologist, 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 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 .
