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.  He 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.  He currently serves as faculty director of the Macaulay Honors College and The Verrazano School at CSI, and until recently was Education Officer and Councilor of the American Astronomical Society.
