Charles Liu


Charles Liu is an extragalactic observational astronomer.  His research focuses on colliding galaxies, starburst galaxies, and the star formation history of the universe; and it also wanders into the realm of quasars and active galactic nuclei.  Charles also has a great love of teaching – informal as well as formal – and he feels a great need to help make the scientific community a better place for all people who wish to be a part of it.  Charles previously served as the faculty director of the Macaulay Honors College and The Verrazano School at CSI, and as Education Officer and Councilor/Trustee of the American Astronomical Society.  He is an associate with the Department of Astrophysics and Hayden Planetarium at the American Museum of Natural History in New York.  Currently, he serves as chair of CSI's Department of Physics and Astronomy, and as president of the Astronomical Society of New York.  In 2020, he was named a Legacy Fellow of the American Astronomical Society.
