<P> Sheldon is a senior theoretical physicist at Caltech and shared an apartment with his colleague and best friend , Leonard Hofstadter ( Johnny Galecki ) . However , Sheldon now lives across the hall with his girlfriend Amy , in the former apartment of Leonard 's wife Penny . He is a former child prodigy with genius level IQ , but displays an almost total lack of social skills , a tenuous understanding of humor , and difficulty recognizing irony and sarcasm in other people , although he himself often employs them . He exhibits highly idiosyncratic behavior and a general lack of humility or empathy . He also lacks toleration . These characteristics provide the majority of the humor involving him , which has caused him to be described as the show 's breakout character . Despite speculation that Sheldon 's personality traits may be consistent with Asperger syndrome , obsessive -- compulsive personality disorder , and asexuality , co-creator Bill Prady has repeatedly stated that Sheldon 's character was neither conceived nor developed with regard to any of these traits . </P>
