the University's Responses to a Diversified Student Body, The Undergraduate Affairs Committee, and the Committee on Courses. Chang long has taken his support for undergraduates to the residence halls, first for many years as a frequent participant in residence-hall guest lectures, faculty dinners and other events. He is often asked to speak at Cal Student Orientation programs. In the fall of 2005, Chang and his wife Abby moved into the residence halls at the University of California, Berkeley, as a part of the Residential Faculty Program. The program gives free room and board in exchange for eight hours of service a week, and is intended to allow students to better know the faculty. The couple live in a three-bedroom suite in Towle Hall of Unit 2, located on Haste Street. They are often seen walking together to and from the Crossroads dining commons.

Chang is the sponsor for the program Papers with the Prof, as well as other random events throughout the school year. He has hosted a martial arts movie night in the past. He, along with Unit 1 live-in faculty member Duncan Williams, have appeared at Crossroads during finals week with free muffin tops to students studying for finals. Chang expresses interest in martial arts films, as well as t'ai chi. Chang is an avid traveler and has visited 47 states in the United States, mostly by Greyhound Bus or rail.
