He then went to Harvard University, where he was editor-in-chief of The Harvard Independent.[6] He graduated in 1993 with a Bachelor of Arts, summa cum laude, in classics. He won a Marshall Scholarship and spent the next two years in England doing graduate study in classics at Keble College, Oxford, receiving a Master of Letters degree in 1995. Shanmugam then returned to the United States to attend Harvard Law School, where he was an executive editor of the Harvard Law Review and argued the case for the winning side in the Ames Moot Court Competition.[9] He graduated in 1998 with a Juris Doctor, magna cum laude.[3]

Shanmugam then entered private practice as an associate at the law firm of Kirkland & Ellis, where he worked for noted lawyer and judge Kenneth Starr. In 2004, Shanmugam became an assistant to the U.S. Solicitor General, where he worked for four years and argued eight cases before the Supreme Court.
