I am a cosmologist/astrophysicist who studies the origin and the evolution of our Universe. I am working as an associate professor at the Astronomy and Astrophysics Department, Eberly College of Science, Pennsylvania State University. I am also a part of the Center for Theoretical and Observational Cosmology (CTOC) at the Institute for Gravitation & the Cosmos (IGC). Prior to this, I was a postdoctoral fellow in theoretical cosmology in Physics and Astronomy department at Johns Hopkins University and the TAPIR (Theoretical AstroPhysics Including Relativity) group in PMA Division (Physics, Mathematics and Astronomy) at Caltech working with Prof. Marc Kamionkowski. Even before, I was a graduate student of Texas Cosmology Center (TCC) and the Astronomy Department at the University of Texas at Austin. My thesis adviser is Prof. Eiichiro Komatsu, and here is my academic tree. I am working on various aspects of theoretical cosmology, but I also enjoy working with real data. In particular, I am working for a high redshift galaxy survey called HETDEX (Hobby-Eberly Telescope Dark Energy eXperiment). The main theme of this mission is studying the properties of dark energy by analyzing the distribution of galaxies (Lyman-alpha emitters). In the current survey design, we shall observe about a million galaxies within the 540-sq.-deg. area in the sky at the redshift of 1.9< z <3.5. We have been collecting data since the summer of 2017!
