Welcome to the online home of Qicheng Zhang! I'm currently a graduate student studying planetary science at Caltech in Pasadena, CA. I mostly work on small body astronomy—comets, asteroids, and related objects that roam the solar system. This site attempts to capture key aspects of my research, and perhaps eventually, some of the other fun things that I'm involved with.

Personal & Academic History

I was originally from China, but largely grew up in Southern California where I've mostly resided in the present millenium. As an undergraduate, I attended UC Santa Barbara where I studied physics within the College of Creative Studies (2013–2017), and have also worked at the U.S. Naval Research Laboratory. I'm presently pursuing a Ph.D. in planetary science at Caltech.

Recent Highlights

2019 Apr 30: Paper Zhang (2019) (arXiv:1904.12850) has been published, on deflecting comets by laser heating, an artificial analog to their natural nongravitational perturbations powered by solar heating.

2018 Jan 3: New paper Zhang (2018) (arXiv:1712.08059) is out, placing practical limits to backtracing interstellar objects like ‘Oumuamua in the present and future.
