Richard Alpert, who later took the spiritual name Ram Dass, and Timothy Leary were both involved in psychedelic research. After a brief visiting professorship at Berkeley, in 1961, Alpert (Ram Dass) devoted himself to joining Leary in experimentation with intensive research into the potentially therapeutic effects of hallucinogenic drugs such as psilocybin, LSD-25 and other psychedelic drugs as part of the "Harvard Psilocybin Project" before being dismissed from the university due to controversy surrounding their experiments with hallucinogens.
