A third-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 chemical evolution of the Milky Way, I have been working with Dr. Sebastien Lépine to study the kinematics of Gaia K and M dwarfs in the local Galactic halo. I'm a graduate astronomy lab coordinator, and a ASTR 1010/1020 lab instructor. I enjoy walking with a cup of coffee (or tea, occasionally), watching movies, reading books, and taking photos.

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