The 19-year-old theater major was fatally shot at the 47th Street Green Line station in Bronzeville Tuesday night, just blocks from his home.
"Kevin will be greatly missed by the faculty staff, and students who lives he touched," said Mark Kelly, Columbia's vice president of student affairs, in an email to students Thursday.
One professor remembered Ambrose Wednesday as a hard-working student whose "warm presence" lit up her introductory theater classroom.
Kelly said the "sense of loss is further felt on campus" as Ambrose's grandmother, Diane Ambrose-Owen, was a former and long-time employee of Student Financial Services.
Instructors can request therapists to visit their class to discuss the incident, and students who want one-on-one counseling can arrange a session with a therapist by calling the Student Relations office at 312-369-8595.
Friends honored Ambrose Wednesday night with spoken word and song performances at at Harold Washington Library.
Brittany Stokes, 20, said Ambrose is the third friend she has seen killed this year.
"We have to go through our friends dying," she said. "I feel this city is some type of poison — it's hitting too close to home."
