Mindy Kaling is probably best known for her work on The Office (the American version), writing, directing, producing, and acting as Kelly Kapoor. I admit that I only know her character's name because I've already read her book, which we're reviewing this week (Is Everyone Hanging Out Without Me? And Other Concerns). She also has a Fox sitcom, The Mindy Project, which was just (in March) renewed for a third season.
She has also been in film, most notably in This Is the End and Wreck-It Ralph.
She has been named one of the "50 Coolest and Most Creative Entertainers" of Hollywood by Entertainment Weekly and one of Time's 100 most influential people in the world, both in 2013.
Mindy Kaling is funny, successful, not a Hollywood twig, and therefore - in my opinion - a great role model for girls (or anyone).
