Second year astronomy graduate student in Department of Physics and Astronomy at Georgia State University. As I have a huge interest in the structure formation and evolution of the Milky Way, I have been working with Dr. Sebastien Lépine to study kinematic properties of K dwarfs in halo using SUPERBLINK/GAIA catalog. I am a ASTR 1010/1020 lab instructor as a teaching assistant. I enjoy watching movies or TV series, reading books (novels or history), and practicing to take cityscape or landscape photos.

I mainly take cityscapes or landscapes, but also try nightscapes and astrophotography.
