Michael Moscovitz is Mia's primary love interest in the novels. In the movie, he is portrayed by Robert Schwartzman. Like his sister he is also very smart with a supposed IQ of 179.
Michael Moscovitz was born on January 5,1986 to Ruth and Morty Moscovitz. He is of Jewish descent and it is known that his family practices Jewish traditions, although it is not known how stringently he adheres to the faith as he is opposed to organized religion. He has a dog named Pavlov and a sister named Lilly.
He attended Albert Einstein High School for Boys (made coeducational circa 1975). Being opposed to most organized groups, he only joined the Computer Club, of which he was Treasurer his senior year. In his free time, he plays the guitar. He lead a band called Skinner Box which disbanded upon the matriculation and separation of many of its members. He had a webzine called Crackhead which became defunct when Michael began wholeheartedly supporting Linux operating systems. The name of his online persona starts as CracKing, then changes to LinuxRulz, then finally to SkinnerBx. In his senior year of high school, Michael begins to date Mia Thermopolis. This relationship influences his ambitions and future plans.
After graduating high school, Michael attends Columbia University. There, he excels at his study of robotics and is invited to spend a year working on a robotic arm for closed heart surgery in Tsukuba, Japan. Michael chooses to take on this endeavor to curry favor with Mia's family and to prove that he is worthy of a princess, although it means breaking up with the emotionally volatile Mia for the time he is away. Upon completion of the robotic arm, dubbed the CardioArm, Michael founds a firm called Pavlov Surgical. He returns to New York City and is awarded an honorary degree from Columbia.
Michael reunites with Mia for coffee and swears his love for her, although she has a new boyfriend. Later, he attends her 18th birthday party and must leave when he is overcome with anger when said boyfriend mock proposes to Mia. He donates a CardioArm to Genovia and tells Mia that his motives are purely selfish, as he wanted to help her father in the election to make her happy because he is still in love with her. At Mia's senior prom, she breaks up with her boyfriend and Mia and Michael resume their relationship.
Lilly is Michael's younger sister. While Michael and Lilly both express grievances with the other, it is clear that their relationship is loving. They often argue over petty issues, like who will put the dishes away or incinerate the tissues after their parents' Adult Survivors of Childhood Alien Abduction Support Group. It is implied that Lilly played a part in bringing Michael together with his longtime girlfriend, Mia by suggesting that he show up to various school dances at opportune times. When Michael and Mia break up in the eighth book, Lilly supports her brother to the extent of refusing to speak to Mia. Later, in the tenth book, Lilly is very supportive of her brother when he presents his CardioArm to Columbia by taking out her many piercings and adopting a more mainstream appearance. She then helps get Michael and Mia back together by insisting that Mia get a direct quote from Michael for her article in the school newspaper and by suggesting that Michael appear at the prom around the end of the year.

Michael is very handsome, with dark hair and peat bog eyes that make Mia feel warm. Michael also has a very nice chest which Mia mentions numerous times in the books. He has very pale skin from staying inside on his computer (and playing his bass) most of the time, this doesn't bother Mia one bit.
