Hsiang-Chih Hwang

Ph.D. candidate in astronomy at Johns Hopkins University

Welcome to Hsiang-Chih's Page

I'm a fifth year PhD student and a Gardner Fellow at Johns Hopkins University. My research interest covers the formation and the evolution of binary stars, white dwarf stars, Milky Way dynamics, active galactic nuclei, binary quasars, and the variability in the sky. Before I came to JHU in 2016, I got my Bachelor degree in Physics and Electrical Engineering at National Taiwan University. I am a coffee and milk tea lover. In my spare time, I like hiking, traveling, and playing badminton.
