A graduate of Princeton University, he completed a PhD in biochemistry at the University of Wisconsin, medical training at George Washington University, and a psychiatric residency at Harvard Medical School. While working as a biomedical researcher at the National Institute of Mental Health before he was a psychiatrist, Fisher had a psychotic episode including hallucinations and delusions. After three months at Bethesda Naval Hospital at age 25, which included forced seclusion and antipsychotic haloperidol, he was discharged with a diagnosis of schizophrenia. He was involuntarily hospitalized three times. He reports being influenced by those who were able to show they cared about the person inside and gave him hope that he might some day recover. He went on to become a psychiatrist. He was told during psychiatric training that "You can't talk to an illness" but believed that talking to the person inside is a key method for building trust and recovery. He has since worked as a psychiatrist in hospitals and clinics, while also being a part of the consumer movement. He said that a very significant part of the reason for becoming a psychiatrist was wanting to bring to the field what he wished had been there when he was going through psychosis He was a member of the White House Commission on Mental Health, 2002-03.

Question: Where did the player who Giles tied for the most touchdowns against the Dolphins in a single game go to college? Passage:Jimmie Giles, Jr. (born November 8, 1954) is a former professional American football player who was drafted by the Houston Oilers in the third round of the 1977 NFL Draft. A , 238lb tight end from Alcorn State University, Giles played in 13 NFL seasons from 1977 to 1989. A four-time Pro Bowl selection, Giles's career flourished as a member of the Tampa Bay Buccaneers during the early and mid-1980s, despite being used mainly as a blocker during several seasons in which he fell into disfavor with the coaching staff. Giles' benching coincided with a training-camp holdout, the first in Buccaneers history by a player under contract, and the difficult Doug Williams negotiations that resulted in his departure for the USFL. Giles' four touchdowns against the Miami Dolphins on October 20, 1985, tied Earl Campbell's record for the most touchdowns by a Dolphins opponent, and is still (as of 2017) the Buccaneers' single-game record; despite this, the Dolphins would win 41-38. Dolphins coach Don Shula said of the performance, "I can't remember any tight end dominating us that way". Buccaneer teammate Gerald Carter said that Giles could have been "one of the best all-time tight ends, if they'd used him more". In 1988 with the Philadelphia Eagles, he caught a touchdown on one of the most memorable plays in Monday Night Football. Quarterback Randall Cunningham escaped a tackle from Giants linebacker Carl Banks and threw a touchdown to Giles.
