	Lisa Randall was born on June 18, 1962 in Queens, New York. She grew up in New York and graduated from Stuyvesant High School in 1980. Interestling enough, another famous physicist, Brian Greene, was one of her high school classmates. After graduating, Randall attended Harvard University where she earned both her A.B. and her Ph.D. in physics. Randall earned her Ph.D. in Pparticle physics under the direction of Howard Georgi. After graduating from Harvard, Randall began her career in Academia with professorships at both MIT and Princeton University. Randall was the first woman to earn tenure in the Princeton Physics Department and the first female theoretical physicists to earn tenure in the Harvard Physics Department.

 Lisa Randall has a sister who is just as brilliant as she is, Dana Randall. Dana Randall is a professor of theoretical computer science here at Georgia Tech. She is also the Director of the Algorithms and Randomness Center and the ADVANCE Professor of Computing. Needless to say, the Randall sisters are both notable female scientists in their respected fields.
