Who is Dr Nowitzki on The Big Bang Theory? Character and cast explored

In The Big Bang Theory, Ramona Nowitzki (Riki Lindhome) is a post-doctoral candidate and alumna of Caltech who has a long-standing, almost obsessive, admiration for Sheldon and his contributions.

Sheldon in The Big Bang Theory used her assistance as a student to help him compute the masses of all the fermions in his paper where he used his theory of string network condensates to reconcile the black hole information conundrum. She worked on her first postdoctoral fellowship at CERN, analyzing LHC signatures of scalar dark energy, before returning to Caltech.

Ramona swiftly became a part of his life in The Big Bang Theory as Sheldon worked towards a breakthrough in understanding how neutrinos arise from a string-net condensate.

At first, Sheldon was relieved to have assistance concentrating on his work, but he became irritated when Ramona insisted he could not spend time doing things he liked, such as reading comic books, watching TV, or going paintballing.

The Big Bang Theory: Exploring Dr Nowitzki’s character

In the "The Cooper-Nowitzki Theorem" episode from The Big Bang Theory, Season 2, following an inaugural seminar for graduate students in physics where Sheldon addressed the group on behalf of the theoretical physics department, Ramona runs into Sheldon in The Cafeteria and makes plans to have dinner in his apartment, she has a crush on Sheldon.

Sheldon responded to Ramona positively by expressing gratitude for having a free dinner. The remainder of the group watched this peculiar turn of events unfold from the couch during their date until she suggested that they should go.

She never stopped helping Sheldon by setting up appropriate working conditions for him, such as fetching him breakfast at the cafeteria and tending to his feet. Unfortunately for Sheldon, she went too far in insisting that he spend all of his time at work and forfeited his favorite activities.

Sheldon tried everything to get rid of Ramona in The Big Bang Theory, including asking Penny for assistance in trying to push her away. Sheldon was eventually able to reconcile his theory of string-network condensates with the black hole information paradox thanks to Ramona's help.

Sheldon was horrified when Ramona proposed that they split credit on the paper after he had inquired how he might pay her back. It is then, that Sheldon finally voices his feelings and, he told Ramona to leave.

Years later in the episode of The Big Bang Theory titled “The Long Distance Dissonance”, Ramona returned to Caltech for her post-doctoral degree. She made her appearance in the show immediately after Amy left for her summer research which concerned both Amy and other of Sheldon’s friends.

Ramona’s intentions weren’t very pure as Sheldon’s friends struggled to stop her from damaging Sheldon’s and Amy’s relationship. Sheldon all this while had been blind and only started maintaining distance after he confirmed that Ramona was seeking a romantic relationship from him.
