Greg Graffin, the lead singer of "Bad Religion", also holds a PhD in zoology and is a biology professor at Cornell University.
Bad Religion is one of the longest lasting and most influential punk bands in history. The band was co-founded by lead singer Greg Graffin in 1979, and he is the only consistent member of the band.
When he isn't yelling into a mic, Graffin is teaching life sciences as a college professor. He's a pretty smart guy.
He double-majored in anthropology and geology as an undergraduate at the University of California, Los Angeles (UCLA),then went on to earn a master's degree in geology from UCLA and received his Ph.D. from Cornell University.
He returned to UCLA to teach Life Science 1 and also teaches at Cornell University.
His intelligence shines through in both his education and music. It's not too surprising that someone who writes political and activist music is smart enough to get a Ph. D. It would definitely be interesting to be a fan of the band and have their lead singer as a professor!
