Reinert has also been associated with the M. Lothaire pseudonymous mathematical collaboration on combinatorics on words.
[3] Reinert earned a diploma in mathematics from the University of Göttingen in 1989.
[4] She went on to graduate study in applied mathematics at the University of Zurich, completing her Ph.D. in 1994.
Her dissertation, in probability theory, was A Weak Law of Large Numbers for Empirical Measures via Stein's Method, and Applications, and was supervised by Andrew Barbour.
[4][5] Reinert worked as a lecturer at the University of Southern California from 1994 to 1996 and the University of California, Los Angeles from 1996 to 1998, and as a senior research fellow at King's College, Cambridge from 1998 to 2000.
