Jim Parsons Biography
Character Profile

Sheldon is the uber geek, he possesses a Master's degree and two PhDs, and conducts string theory research at Caltech, where he started in 2003. He shares an apartment with Leonard.

Unashamedly geeky, he has no qualms about speaking Klingon; he doesn't mind sharing details of his life that others might find embarrassing, such as a common activity being Klingon Boggle until the wee hours. He wears vintage t-shirts sporting superhero logos.

As a child prodigy, Sheldon was involved in numerous experiments as a child. His plan at age 13 to provide free electricity for his town by building a nuclear reactor was stopped only by government pen pushers claiming to store yellow cake uranium in a garden shed is illlegal! Sheldon started college at the age of 11, receiving his first PhD at 16.

While he might claim to be the perfect human specimen, Sheldon does have his faults - although he is not aware of them. He lacks empathy, is unable to discern sarcasm, doesn't like change, and has an inflated ego. He does not understand social norms, and makes little attempt to do so.
