This Dr is Up in Smoke

That would be Dr. Cheech Marin. He was honored at Otis' commencement ceremonies on May 12th with an honorary doctorate.

While many known him only as half of the famous duo of inhalers in all the Cheech and Chong movies, Dr. Marin has also been amassing a very strong collection of Chicano art, including work by several Otis alums including Eloy Torrez and Patssi Valdez. In a recent Los Angeles Times article Agustin Gurza identified him as "...the nation's leading advocate for Chicano art." In the same story he was lauded for his donation of prints to several museums and universities.
