Karen Livescu
klivescu at ttic.edu

Professor
Toyota Technological Institute at Chicago

(Note: I am on sabbatical for the 2023-24 academic year. I am a Visiting Scholar at Stanford and a Special Faculty Researcher at CMU.)

My main research interests are in speech and language processing, as well as related aspects of machine learning.

I am a Professor at TTI-Chicago, a philanthropically endowed graduate institute for computer science located on the University of Chicago campus. I am also a courtesy faculty member in Computer Science, and Affiliated Scholar at the Data Science Institute, at U. Chicago.

TTIC is recruiting students to our PhD program, as well as additional faculty, including in speech and language-related areas (more on Speech and Language at TTIC).

I completed my PhD in 2005 at MIT in the Spoken Language Systems group of the Computer Science and Artificial Intelligence Laboratory. In 2005-2007 I was a post-doctoral lecturer in the MIT EECS department. In 2008 I was a Research Assistant Professor at TTI-Chicago.
