I am a cosmologist/astrophysicist who studies the origin and the evolution of our Universe.
I am working as a professor at Astronomy and Astrophysics department, Eberly College of Science, the Pennsylvania State University. I am also a director of the Center for Theoretical and Observational Cosmology (CTOC) in the Institute for Gravitation & the Cosmos (IGC). Prior to this, I was a postdoctoral fellow in theoretical cosmology in Physics and Astronomy department in the 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 in the University of Texas at Austin. My thesis adviser is Prof. Eiichiro Komatsu, and here are my academic trees from mathematics genealogy project and academictree.org
I am working on various aspects of theoretical cosmology, but I also enjoy working with the 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 properties of dark energy by analyzing the distribution of galaxies (Lyman-alpha emitters). In current survey design, we shall observe about a million galaxies within 540 sq. deg. area in the sky at redshift of 1.9 < z <3.5. We have been obtaining data from 2017.
