'Blossom' star Mayim Bialik was a '90s trendsetter for teens everywhere with her funky style and all those flowery hats. But what has she been up to since the show ended?

Then:

Mayim Bialik played the title character on the hit series -- a teen girl whose mom leaves her to live with her father and two brothers, including '90s teen heartthrob Joey Lawrence (whoa). You may have also seen Bialik on 'The Facts of Life,' or as the younger version of Bette Midler's character in the tearjerker chick-flick 'Beaches.'

Following the end of 'Blossom' in 1995, Bialik mostly did voice-over acting work for shows like 'The Real Adventures of Jonny Quest' and 'Recess.' It wasn't until 2005 that Bialik got back into acting proper, appearing on episodes of 'Curb Your Enthusiasm,' 'Bones,' and 'Saving Grace.' She also notoriously appeared in an episode of the TLC series 'What Not to Wear,' in which she sought fashion advice and a makeover for her dowdy look.

In 2007, Bialik received her PhD in neuroscience, and used that geeky knowledge to help land a recurring role on 'The Big Bang Theory' in 2010. She continues to act on the show and earned a well-deserved Emmy nomination for her role in 2012.
