She is the Grace Murray Hopper Professor of Computer Science at Yale University and currently serves as the Computer Science Department Chair. At Yale she also holds courtesy appointments in the Department of Economics and the Law School. Feigenbaum co-invented the computer-security research area of trust management.

Feigenbaum did her undergraduate work in Mathematics at Harvard University. She became interested in computers during the Summer Research Program at AT&T's Bell Labs between her Junior and senior years. She then earned a PHD in computer science at Stanford University, under the supervision of Andrew Yao, while working summers at Bell Labs. After graduation she joined Bell Labs. She became the Hopper Professor at Yale in 2008.

She is married to Jeffrey Nussbaum. They have a son, Sam Baum. Baum was chosen as child's surname as the greatest common suffix of Feigenbaum and Nussbaum.

In 2001, Feigenbaum became a fellow of the Association for Computing Machinery for her "foundational and highly influential contributions to cryptographic complexity theory, authorization and trust management, massive-data-stream computation, and algorithmic mechanism design." In 2012 she was named a fellow of the American Association for the Advancement of Science and, in 2013, a member of the Connecticut Academy of Science and Engineering. The Connecticut Technology Council chose her as a Woman of Innovation in 2012. She acts as one of the three award-committee members on ACM SIGecom test of time award.
