After earning a bachelor's degree in mathematics in 1980 from the University of North Carolina, with highest honors and Phi Beta Kappa, Dietrich went to Cornell University intending to get a graduate degree in mathematics. However, after working as an intern at the United States Department of Energy, she switched to operations research.

She is the co-editor, with Rakesh V. Vohra, of Mathematics of the Internet: E-Auction and Markets (IMA Volumes in Mathematics and its Applications, Springer, 2002).

Dietrich was named an IBM Fellow in 2007. She is also a Fellow of INFORMS, elected in 2010. In 2014 she was elected to the National Academy of Engineering "for contributions to engineering algorithms, frameworks, and tools to solve complex business problems".
