About Me
I'm a post-baccalaureate Research Assistant in the Department of Physics and Astronomy at the Johns Hopkins University, working on PHANGS stellar associations. I also work on exoplanet hosts' photometric monitoring for stellar activity. I am applying to Ph.D. programs in the 2024–25 cycle (Fall 2025 start date).

What's here?
- I'm from Beijing, China. My Chinese name is 田秋实. Tian/田 is my family name. Qiushi/秋实 is my given name, roughly pronouced as "tsyu-shri." You can listen to the pronounciation on Google Translate. I always go by Chris.
- I took the banner photo of the Orion Nebula (Messier 42) myself! With my own 4-inch reflector and my dad's Cannon 5D Mark II when I was... oh gosh, I don't remember!
