Rajesh^[1] Ramayan ^[2] "Raj" ^[3]Koothrappali^[4], Ph.D., is an Indian astrophysicist and Howard Wolowitz's best friend. He often hangs out at Leonard and Sheldon's apartment. Originally from New Delhi, Raj has an Indian English accent and, ironically, dislikes Indian food and culture. He frequently portrays himself as having come from humble origins and growing up in poverty in India, only for his friends to remind him that his father is a gynecologist, drives a Bentley, and has a house full of servants. Raj fell in love with astronomy while attending Cambridge University.^[5] For the first six seasons, his principal characteristic was a case of selective mutism, which did not allow him to talk to women outside of his family. This condition could be suppressed through alcohol (or if he thought he was drinking alcohol) or experimental social anxiety medications; however, the former usually ended up changing his personality, making him more obnoxious and overbearing, while the latter tended to have unpredictable side effects. He finally overcame his selective mutism in the season 6 finale "The Bon Voyage Reaction".

CareerEdit

Dr. Rajesh Koothrappali is an astrophysicist and faculty member at Caltech's Physics Department. His expertise includes searching for Trojan asteroids at the Earth-Sun L5 Lagrange point. For his discovery of a planetary object beyond the Kuiper belt, 2008 NQ17 (which he calls "Planet Bollywood"), he is included in People magazine's "30 Under 30 to Watch", granting him some form of celebrity status and a larger office for his work. He is also known for a publication on Kuiper belt object size distribution, having run a simulation to correct for the observational efficiency, and was awarded the Newcomb Medal. However, the work Raj performs at the university is repetitive enough that he could conceivably be replaced by a simple software program, and he fails to observe an exoplanet orbiting the star Epsilon Eridani with his much anticipated time using a ground-based telescope operating in Hawaii.

During The Pirate Solution, when Raj's research testing the predicted composition of trans-Neptunian objects ends, his working permit and visa are bound to become void, as they are only valid as long as he is employed. He seeks out a research position in stellar evolution with Professor Laughlin. However, the job proposition fails as the research team includes an attractive female, Dr. Catherine Millstone, and Raj accidentally drinks a little too much alcohol, causing him to make a sexually explicit comment. To avoid Raj's deportation to India, Sheldon asks him to work for him and, after several disputes, he agrees.

Wanting to be the male "Indira Gandhi of particle astrophysics," Raj researches dark matter. With Sheldon, he explores the string theory implications of gamma rays from dark matter annihilations and considers methods of optimizing a detector for 500 GeV particles to look for the annihilation spectrum resulting from dark matter collisions in space. While Sheldon argues that slow-moving xenon doesn't produce ultra-violet light, Raj posits that xenon can emit the tell-tale ultra-violet light from dark matter collisions, potentially negating a series of dark matter discoveries, and points to neutron scattering data.

CharacterizationEdit

Originally from India, Raj is slightly clueless about American culture and idioms, and dislikes Indian food and his home country. Sheldon even disputes his knowledge of Indian customs and Hinduism, and reveals Raj's native language is English, while he seems to speak fluent Hindi. Raj stated that the reason he puts up with Sheldon is so that he could be reborn as a "well-hung billionaire with wings", according to his Hindu belief of being rewarded after reincarnation for suffering willingly; to Raj, karma is "practically Newtonian". He hates Indian music; however, he does appreciate the Indian lullabies his mother sang to him, and the catchiness of Hindi phrases, two mentioned phrases being "जो जी करे कर" - "whatever floats your boat;" and "Fever 104, बहुत अच्छा संगीत के मौजूदा घर. The phrase means: Fever 104, home of the really good current music."

On the rare occasions when he actually gets homesick, he picks up the latest issue of "Bombay Badonkadonks" and performs Bollywood dancing. He is hypocritically sensitive to others' racist jokes about India, due to he himself not above making derogatory remarks about India, or, in his view, "Gandhi-ville". Raj also claims he can hold out from noxious gases because he grew up in India. Raj likes to say that he comes from the "exotic" subcontinent of India and had to overcome poverty and prejudice, to make himself appear interesting and mystical, especially when he is womanizing. More often than not, he likes to be associated with Slumdog Millionaire, except when Howard's mother says it. Much like how Howard rarely follows kosher, Rajesh eats beef and believes that some of the Hindu Code of Manu is crazy.

He used to have the recognized psychological condition selective mutism, a social anxiety disorder which renders him unable to talk to women (with the exception of family members, who are seemingly unaware of his condition, and deaf women as seen in the Wiggly Finger Catalyst when he can talk in front of Emily), although he quickly learned that he is able to surpass this problem by consuming alcohol-containing foods and medicine, or experimental anti-anxiety medication. Consequently, the alcohol alters his nature and the medications tend to have side effects, such as involuntary face and hand motions, loss of rationality, or jovially stripping naked in public without cognizance of its inappropriate nature. Raj is also able to speak in the presence of women if they are part of a crowd, if he thinks he has been drinking alcohol (under a placebo effect as seen in The terminator decoupling when he talks to Summer Glau while drinking non-alcoholic beer but when Howard points out it is non-alcoholic he can no longer speak to her ), or if he is unaware of their presence. Raj has noted, however, that this is an improvement over his previous affliction, in which the presence of women would cause him to lose bladder control; this was mostly remedied by meditation methods of ancient Indian gurus. Rajesh still has a "nervous bladder", in the sense that he gets an urge to relieve himself when under stress. In the season finale of Season 6, The Bon Voyage Reaction, after breaking up with Lucy, while talking with Penny, he is...well, talking to Penny, which teaches him that breaking things off with Lucy allowed him to finally overcome his selective mutism. As of Season 7, he will likely no longer require alcohol in order to speak in front of females other than family or deafs.

One of Raj's primary personality quirks beside his selective mutism is his tendency to speak or act inappropriately in most situations. One primary example of the latter was when, in The Love Car Displacement, he enters Leonard and Penny's room while they are about to have sex, climbs into bed and goes to sleep, completely unaware of what he interrupted. On another occasion, he openly acknowledged having had crushes on Penny and Bernadette directly in front of them, simultaneously making them uncomfortable and making Amy upset, and fails to recognize Amy's change in mood despite Penny and Bernadette's discreet efforts to indicate it to him. Seen in The Santa Simulation.

He complains that he is lonely, which leads to Raj hating himself and needing to be reassured of his value. While usually sweet, Raj sometimes smiles at his friends' misfortunes. Whenever Raj gets an idea or wants to say something slightly controversial in a conversation, he whispers it in Howard or someone else's ear whenever a woman is around. Howard does refuse to say it out loud because he finds it stupid, offensive, or inappropriate, but he ends up saying it anyway through scoffing at Raj. He also has arguments with Howard often, being akin to those of a married couple. He is noted for using "gangsta" slang, such as "fo' shizzle" and repeatedly using the word "dude".

He enjoys reading DC Comics, as do his friends, but he dislikes Aquaman. Raj often obsesses over almost-insignificant details in fiction, such as how toilets work in Atlantis, the possible symbolism of ponytails in Avatar, whether Wolverine's prostate is made of adamantium, what zombies would eat if humanity was exterminated, how vampires would shave themselves since they can't see their reflections, etc. He has experienced gaming addiction and, like Howard, he idolizes Stephen Hawking. Unlike the other guys, Raj has shown great interest in some non-geeky things like John Grisham novels and Archie comics, the latter being shared with Zack. Raj also has an interest in a number of books and TV shows which are generally targeted towards the female demographic, such as Twilight, The Good Wife, Grey's Anatomy, Sex and the City, Eat, Pray, Love, and Bridget Jones's Diary. He is normally seen wearing a layered combination of a shirt, a sweater vest, and a windbreaker with khakis and skate shoes; he wore a red cap in the Pilot.

FamilyEdit

• Parents: Dr. and Mrs. Koothrappali
• Sister: Priya Koothrappali
• Brothers: 3 Unnamed Brothers
• Sister: 1 Unnamed Sister
• Grandfather: Unnamed Grandfather
• Cousin: Venkatesh Koothrappali
• Cousin: Sanjay Koothrappali
• Uncle: Unnamed Uncle

Raj always communicates with his parents, Dr. V.M. and Mrs. Koothrappali back in India via webcam. They constantly try to arrange dates for him. Raj's parents want their son to marry a woman of Indian descent and give them grandchildren. Mrs. Koothrappali is especially worried that despite Raj being old enough to marry, the closest they have to a daughter-in-law is "that Jewish boy," Howard. When they become meddling or judgmental, he often "brings his parents" into Leonard and Sheldon's apartment via his MacBook Pro, to seek his friends' support in the discussion. Like his "baby sister" Priya, whom he is very protective of, Raj calls his parents "mummy" and "daddy".

Despite Raj's claims that he grew up in poverty, his friends like to remind him that he comes from a very wealthy

background. His father is a gynecologist, drives a Bentley, and has a house full of servants, two of them children. Raj later admits this, saying they are very wealthy. His parents say this too, believing they have nothing to complain about as they are very rich in a very poor country. In "The Wiggly Finger Catalyst", it is revealed that his parents are actually billionaires, as Sheldon claims that Raj's family's estimated wealth is 'halfway between Bruce Wayne and Scrooge McDuck', a reference to Forbes: The Fictional 15.[This quote is seen in The Wiggly Finger Catalyst].

Not much of Raj's family is known so far. Raj comes from a family of six children; Raj is mentioned to have an older brother in one episode, who, according to Raj, gave him his 'Patang' (fighter kite). His older brother appears to be among three brothers, according to Raj's statement in The Hot Troll Deviation. It was also in this episode when Raj claimed that he has two sisters, one of them Priya.

Raj's cousin Sanjay Koothrappali works in a Call Center run by AT&T. In "The Guitarist Amplification", Raj tried to avoid going to his wedding, but eventually accepted his parents' offer.

Another cousin, Venkatesh (who appeared in "The Precious Fragmentation"), works as a lawyer in Mumbai. He has poor negotiation skills, even admitting that he is useless when Raj was trying to negotiate for a jet ski.

In "The Griffin Equivalency", Rajesh points out that his limo is bigger than the house that his grandfather grew up in and has more food too, suggesting that his family was not always wealthy.

In "The Alien Parasite Hypothesis", Raj mentions that Type 2 diabetes runs in his family, but he has no symptoms so far.

RelationshipsEdit

FriendsEdit

Leonard Leakey HofstadterEdit

Leonard and Raj meet at the University in "The Staircase Implementation". Made clear in "The Jerusalem Duality", both Raj and Howard like Leonard. Though, Raj takes delight in Leonard's problems with Penny and becomes somewhat adversarial with him when he dates his sister, Priya. Despite his tendency to tease Leonard about his girlfriend issues, he is genuinely supportive of his and Penny's relationship and frequently attempts to get him to break up with Priya (sometimes employing subtle manipulative techniques, such as feeding his paranoia about the two women comparing notes about his sex life). Raj feels jealous when Leonard and Howard use his ideas for fun and exclude him. Raj has said that Leonard only hangs out with him if he has no other options, and has missed him ("The Spaghetti Catalyst"). When Sheldon and Penny were indisposed, Leonard took the very appreciative Raj with him to Switzerland for a visit to the Large Hadron Collider after both Penny and Sheldon fall sick [as seen in The Large Hadron Collision. They normally try to help each other. In "The Date Night Variable", Raj hangs out with Leonard and Penny on their date and gets thrown out when he tries to get Penny to tell Leonard that she loves him.

Sheldon Lee Cooper Edit

Generally, Raj is much more patient with Sheldon than Leonard, Howard and Penny. When asked, he mentions it is because of his belief in Karma. Sheldon, however, appears oblivious to this, as he once tried to cut off Raj from his circle of friends to make room for Barry Kripke and because Raj got one answer for his questionnaire wrong. Raj was terrified at the prospect of losing Sheldon as a friend, and later worries whether he is merely the "treasured acquaintance." Sheldon hates it when Raj is talking in his ear, although he does appreciate Raj's words. Whenever Raj is upset, Sheldon brings him a hot beverage to console him, although this is because his mother would make him. In The Roommate Transmogrification, Raj proves to be a better roommate to Sheldon than Leonard was, as he goes out of his way to impress him. Considering Raj a good friend, Sheldon enjoys the ethnic diversity he brings about in the group and the fact that he too likes monkeys and trains. In the episode "The Pirate Solution', when Raj's research hits a dead end, Sheldon offers Raj a chance to work for him, which he later accepts. Since then, Raj has been working for Sheldon, and they occasionally clash. Raj maintains that he does not work for Sheldon but with him and Sheldon agrees on the opposite, making Raj as the person who works for/with Sheldon. They also have a nerd war over the overly large desk Raj moved into his office. This is seen in The Hot Troll Deviation.

Howard WolowitzEdit

Howard is Raj's best friend; since Season 1, they have always been very close and met about the same time they were introduced to Leonard and Sheldon. Raj usually comes to Howard's house for holidays such as Thanksgiving, and has sleepovers there, as well. He knows all of Howard's jokes and finds humor in mimicking Mrs. Wolowitz. Rajesh is sometimes sensitive to Howard's cultural stereotyping as well as his perceived inability to recognize when he is upset. They are practically inseparable, maintaining certain weekly routines together and serving as wingmen to each other. Although Raj and Howard are heterosexual, their relationship and interaction sometimes resembles that of a couple, which resulted in Leonard's mother, Beverly Hofstadter, calling their relationship an "ersatz homosexual marriage". As seen The Maternal Congruence and The Maternal Capitance despite the denials, Raj amusingly still takes up a stereotypical "female" role in arguments with Howard, for example, accusing him of deserting him for any opportunity to speak with an attractive woman. During Howard's launch in The Countdown Reflection, both he and Howard's wife Bernadette express their love for Howard and hold hands.

PennyEdit

Penny is the closest female friend that Raj has, though he is only able to talk to her when he is drunk. Penny sometimes tries to make Raj speak, but mostly feels sorry for him, such as by calling him a strange little man, damaged, and even kissing him on the cheek, while Raj believes her to be considerate of him. There are times where his relationship with Penny becomes less than platonic - particularly in "The Griffin Equivalency", where he misinterprets her going with him to an award ceremony as an act of romance rather than friendship and introduces Penny to his parents as his "new squeeze" while he was drunk. He tried to apologize by note, but Penny forced him to say the apology while sober. In "The Roommate Transmogrification", Raj and Penny hooked up while they were drunk, and, while they were leaving the bedroom, ran into Howard, Leonard, and Sheldon. In "The Skank Reflex Analysis", Raj reveals to Penny that they did not have sex or any physical activity instead, Raj ejaculated prematurely when Penny tried to help him put on his protection  and then they fell asleep. Raj asks Penny not to tell anyone about this, to which Penny agrees. They accept to go back to being just friends. She agreed that he could tell others that "their light shone too quickly and brightly", but couldn't tell people that he "ruined her for white guys". In "The Wiggly Finger Catalyst " Penny sets him up with a deaf friend of hers that can communicate with him by signing.  In " The Santa Simulation" Penny invites him along to a girls' night out and they try and find him a girl although nothing works out.

BernadetteEdit

Raj's relationship with Bernadette is somewhat strained, because of him having secret feelings of her and fantasizing about Howard leaving and he needing to fufill her sexual needs. When Penny starts a false rumor that Bernadette is breaking up with Howard, Raj begins to awkwardly hit on her at the CheeseCake factory (after drinking a grasshopper). When Howard proposes to her, Raj is the only one to encourage him to propose, as they all knew the result. Howver, when Benadette accepts his proposal, Raj is crushed. In the season 5 premiere Bernadette is angry because Raj has been having recurring dreams about her. A lot of what Raj does Bernadette finds creepy. 

Amy Farrah FowlerEdit

Raj's relationship with Amy has not been properly explored yet, but they are shown to be friends and she can find it weird that he can't talk to women. After Sheldon invites the lonely Raj on his and Amy's anniversary date, he wants to get to know his better and she tells him to go home. In "The Santa Simulation " on, he tells Amy that he was never interested in her like his crush on Penny and Bernadette. She then draws him out that they were both missed the company of the opposite sex. They talk about their humiliations while growing up until Raj says that he hopes that the girl he finds is as half as a lovely person as Amy. Amy then says that he "wants me, I'm good". She says that they can leave now, obviously getting back at Raj. Then Raj tells Penny on the way out that now he may fall for Amy.

Stuart BloomEdit

Beginning with the "The Date Night Variable", Raj becomes closer friends with Stuart since Howard is away on the ISS. They go out to bars looking for ladies and do other things Raj and Howard used to do. Stuart also moves in with Raj to get out of the back of the comic book store.

RomanticEdit

Unlike the other main characters, Raj's romantic relationships have never been very serious or lasting, mostly due to his inability to speak to women. He has had a number of one-night-stands and brief dates. Impressively though, Raj was the first one amongst the four to get laid within the series in "The Middle Earth Paradigm" at Penny's Halloween party. He is much more successful in casual sex than the more sexually aggressive Howard, and, amongst the guys, has great appeal to extremely attractive women. He has a big crush on Howard's fiancée, Bernadette Rostenkowski, who has said how wonderful a man he is and has called him a "cutie pie", much like Penny.

Lalita Gupta (Sarayu Rao)Edit

One of Raj's female childhood acquaintances, Lalita Gupta used to be fat. She also kicked him in the samosas (testicles) and called him untouchable. In spite of this, Raj's parents thought it would be a good idea to set them up on a date. Raj discovered that alcohol (grasshopper cocktail) is able to help him suppress his selective mutism but being drunk made him obnoxious. As a result: he generally weirded out Lalita. Sheldon, because of Lalita's resemblance to a beloved childhood fairy tale character, Princess Panchali, unintentionally "stole" Lalita from Raj causing him to get angry with Sheldon.

Missy Cooper (Courtney Henggeler)Edit

In "The Pork Chop Indeterminacy", Sheldon's fraternal twin sister, Missy, came to Pasadena. Raj at the time was using an experimental drug to help with his selective mutism. Leonard, Howard and Raj were all attracted to her and after hitting on her too much (causing her to hide at Penny's for the night) and fighting over the "right" to ask her out, they decide to just ask her out individually. After both Leonard and Howard's attempts failed, Raj got his turn. Inconveniently, as he waited for her at Penny's door, the drugs began wearing off and despite Missy's implied interest in Raj, (saying "Hi cutie pie, I was hoping you'd show up") Raj was unable to ask her out and walked away.

Summer GlauEdit

In "The Terminator Decoupling", when Sheldon, Leonard, Howard, and Raj were on a train to San Francisco, the latter three tried talking to sci-fi actress Summer Glau. After drinking what he thought was a beer, Raj talked to Summer, being flirtatious and smooth and she took a liking to him. He said Slumdog Millionaire was based off of his life story and revealed his knowledge of astronomy. When Howard pointed out that his beer was non-alcoholic, Raj stopped in the middle of his conversation, was embarrassed and rushed away from Summer without saying any more.

Abby (Danica McKellar)Edit

In the episode "The Psychic Vortex", Leonard and Howard went on a double date with their respective girlfriends, leaving a lonely Raj with only an indifferent Sheldon. Raj insists on Sheldon helping him score with a girl at a University Mixer. After presenting Sheldon with a "Limited Edition Green Lantern Lantern" and a "Incredible Hulk Hands signed by Stan Lee" on two separate occasions, Sheldon agreed to be Raj's wingman, helping him score with Abby. It is not known what happened to her after that episode.

Dr. Elizabeth Plimpton (Judy Greer)Edit

In "The Plimpton Stimulation", Dr. Plimpton was welcomed as a guest of Sheldon's for a few days while considering taking a position at the University. Incredibly promiscuous, she shows interest in Raj immediately after meeting him despite having slept with Leonard the previous night and sitting next to him at the time. That evening, Raj was hosting Dr. Plimpton but when Leonard and Howard show up, she immediately suggests they join Raj and her. Raj directs his friends so they can leave and spends the night with Dr. Plimpton.

Angela (Tiffany Dupont)Edit

Rajesh and Sheldon met Angela at a coffee shop while Raj was trying to test an experimental social anxiety drug. Raj told her she was very beautiful when she asked why he was staring, and flattered, she liked his accent, stating she was interested in going to India. As she welcomed him sitting with her, Raj introduced them as Dr. Rajesh Koothrappali and Dr. Sheldon Cooper, scientists who like to observe, and dismissed Sheldon off to buy a scone. Koothrappali complemented her name, citing its etymology, to which she responded he was cute. However, a side effect of the medication caused him to begin stripping, which scared her away, while he told Sheldon he was being rude and attempted to continue with her saying she had the expressive face of an actress.

Emily (Katie Leclerc)Edit

In "The Wiggly Finger Catalyst", Penny thought she found the perfect match for Raj by hooking him up with a woman who is deaf, Emily. Raj made very obnoxious remarks during their first date, but translator Howard would sign something else to Emily as to make him not look like a jerk. However, it turns out she liked Raj only for his money and left him when she found out his parents would cut their financial support if they continued to see each other.

Siri (Becky O'Donohue)Edit

After Raj buys a new iPhone 4S in the "The Beta Test Initiation", he develops a peculiar relationship with his phone's voice command personal assistant, Siri. Contrary to his usual inability to speak to women directly, Raj is able to address her, as she is a mere voice. Whenever Raj inquires about an activity he wishes to engage in or a destination, she provides suggestions (like a wine selection for a dinner party) or a list of possible locales, of which a subset is emphasized due to proximity. In reaction to Raj, Siri is able to accept compliments, respond to inquiries about her well-being, and display emotions, like gratitude. Upon Raj's request to be called "sexy", Siri complies and Raj, in turn, refers to her as "darling". Raj appears to be actually dating Siri by taking her places, having human conversations with her and buying her gifts. However, Raj has a dream that he goes to meet Siri in the form of a real woman, but, of course, when she turns around, he can't speak to her. Thus, an offer to make love to her is unable to be fulfilled. He then wakes up screaming "NOOOOO!"

Lucy (Kate Micucci)Edit

In "The Tangible Affection Proof" Raj and Stuart put together a Valentine's Day party for those who do not have dates. Raj figures that their group should not keep beating themselves up and he makes a speech that they shouldn't measure their self-worth by whether they are in a relationship and that they are not alone because together they are a community. Lucy walks up to Raj to tell him that his speech was really cool. They leave to have coffee together.

The next episode "The Monster Isolation" picks up with them having coffee. Raj explains more about himself when Lucy excuses herself to the Bathroom. While Raj gets more Chai Tea Lucy is seen escaping through the bathroom window from the shop and running away. Raj is next seen a few days later by Leonard and Howard after he fails to show up at work. He is upset because Lucy ditched him and proclaims he's never leaving his apartment. Rajesh's apartment is a mess and he is ordering his food on line. Later the guys run into Lucy at the comic book shop as she left off a note for Raj. Howard calls her out for her ditching him and takes the note with her phone number. Howard later gives Raj her number and the two agree to meet. Lucy reveals that she has anxiety issues. Pushing herself to meet people she shows up at the Valentine's Day Party after seeing a flyer explaining that she doesn't even like comic books. To make her more comfortable Raj explains his own anxiety with women and his inability to talk to them without alcohol. He proclaims he's just as messed up as her and begs her for a chance to prove it. The two agree to go out on another date.

At Penny's, Raj seeks advice on a killer first date with Lucy. Amy says that evolutionary biology shows that women like men that are steady in the face of danger and suggests an unsafe environment. Raj mentions that Lucy has some social anxieties and wants something simpler. Bernadette suggests Disneyland's Space Mountain ride where you can hold hands in the dark though Raj doesn't think Lucy would like the crowds. After the girls get excited to go to Disneyland themselves, they can't come up with any other helpful suggestions.

Later Raj sets a table at a library with picnic paraphernalia for his date with Lucy. she arrives and Lucy asks if they are eating there. Raj texts her that they are having a "texting date". She replies that she likes the idea. He also tells her to remember that he has an adorable accent. They have a good time laughing at each other's comments. Lucy tells him that she does web design for porn sites. Raj denies even knowing what it is but, due to an auto-correct error, she says she really works on prom sites. Raj texts back he really likes proms but when Lucy looks at him funny, he texts that it was auto-correct and that it should be that he likes sports. Lucy and Raj finish their date when her phone battery runs out. She says she had fun and that this date definitely pushed her comfort envelope. Lucy flees with a panic attack when she tries to kiss Raj. Raj says he is still counting it as foreplay.
