8. Mayim Bialek

If you ever wonder how Mayim Bialek can be so convincing as Amy on The Big Bang Theory, it has a lot to do with the fact that she has a Ph.D. in neuroscience in real life. She was a child star playing the lead in Blossom and then went on to get her degree in neuroscience from UCLA. She continued her studies until 2005 when she took a break to pursue acting, landing the role of Amy. She finished her Ph.D. in 2007.
