Ramona Nowitzki

Ramona Nowitzki is a postdoctoral researcher and former graduate student of Caltech who is a huge fan of Sheldon's work and has a crush on him. As a student, she helped Sheldon calculate the masses of all the fermions in his paper reconciling the black hole information paradox with his theory of string network condensates. Prior to her return to Caltech, she performed analysis of LHC signatures of scalar dark energy at CERN for her first postdoctoral fellowship.
In the Season 2 episode "The Cooper-Nowitzki Theorem", after attending an opening seminar for physics graduate students with Sheldon speaking on behalf of the theoretical physics sector of the department, she meets Sheldon personally in The Cafeteria and arranges to have dinner with him in his apartment. Where other people might be worried about such behavior being reminiscent of stalking, Sheldon reacts positively to Ramona by appreciating the fact that he's getting a free dinner. During their date, the rest of the gang is sitting on the couch as spectators of this strange turn of events until she implies that they should leave.
She keeps "helping" Sheldon by arranging suitable working conditions for him, such as getting breakfast for him at the cafeteria and giving caring for his feet. Unfortunately for Sheldon, she overdoes her insistence that Sheldon dedicate his time solely for work, depriving him of his favorite hobbies such as playing games, watching TV, and going for paintball with the guys. Even more unfortunately for Sheldon, he can't seem to get rid of her, especially when she settles herself in his apartment (on the couch). At times, she appears very suddenly and stalks around the apartment staring at people like the T-X terminator from Terminator 3: Rise of the Machines.
Ramona proves to be irritating for the entire group, especially when she assumes that Penny likes Sheldon. She still asks Penny to be sisters with her. She makes it difficult for anyone to communicate with him and scares them away.
Eventually, Sheldon solves the problem he's been working on. Enthusiastic about his solution, he asks Ramona how he can reward her for all her help. When she asks for him to share credit with her and name the theorem "Cooper-Nowitzki", he finally kicks her out of the apartment. Ramona finally sees Sheldon true colors as a rude arrogant jerk as he is. Ramona leaves passing by Penny, who asks if they are still "sisters'. ("The Cooper-Nowitzki Theorem")
She reappeared in the Season 10 finale "The Long Distance Dissonance", hanging around Sheldon while Amy is away at Princeton University. By this time Ramona had her PhD. It turns out that despite seeing his true colors earlier, she never stopped having feelings for him. The gang becomes worried for Sheldon when she begins chasing him again. Ramona eats with him, goes swimming with Sheldon and visits with the gang in apartment 4A. Sheldon was told by Penny of her romantic interest in him and seems to finally understand. At lunch, Sheldon asks her if she has a romantic interest in him, she asks him "What if I do?" and then kisses him. Sheldon is shocked and then immediately flies to New Jersey to propose to Amy. 
She reappeared in the Season 11 premiere, "The Proposal Proposal", where Raj asked her out again, but she declined. Raj tells her about Sheldon and Amy's engagement which she already knew about. She appears in the final scene where Amy comes up to her and the guys expect a fight between the girls for Ramona kissing Sheldon. Instead Amy thanks her for getting them engaged and hugs her, with a confused Ramona patting Amy with a nervous smile.
