[1] She earned her Ph.D. in 2003 from the Massachusetts Institute of Technology under the supervision of Alan Edelman, with a thesis on Eigenvalue statistics for beta-ensembles.

[6] Dumitriu won the Alice T. Schafer prize for excellence in mathematics by an undergraduate woman in 1996.

[2] In 1995, 1996, and 1997 she won the Elizabeth Lowell Putnam Award that is given to the top woman in the contest, a record that was not matched until ten years later when Alison Miller also won the same award in three consecutive years.
