I got my Ph.D. in the Department of Physics and Astronomy at Vanderbilt University, studying Astronomy, Astrophysics and Cosmology. My advisor is Prof. Andreas Berlind.
Before I came to Vanderbilt, I completed my Bachelor's and Master's degree in Physics at Fudan University in Shanghai, China, which is also my hometown.

My research interests go across many orders of magnitude, from the Galactic structure of our Milky Way to the very large scale structure of the Universe. I use computational simulations, as well as astronomical survey data.
The standard inflationary paradigm predicts nearly Gaussian and scale invariant primordial density fluctuations. However, even the simplest inflation model predicts some small deviation from Gaussianity. Constraining and detecting primordial non-Gaussianity provide a very powerful tool to probe the very early universe. We use LasDamas simulations to test different observables of large-scale structure as probes of primordial non-Gaussianity.
Voids are very underdense regions in the universe that contain very few or no galaxies. Though finding voids is not an easy job, voids occupy huge amount of volume in the universe and contain lots of information about the cosmology. Using cosmic voids to constrain cosmological parameters is a very interesting and challenging project.
Stars in our Milky Way provide invaluable information about the Galactic structure as well as galaxy formation in general. We plan to use correlation function statistics of stars to study the Galactic structure. The SEGUE sample of G-dwarf stars represents an unbiased random sub-sample of the stars in a big volume, thus is great samples to use.
