Elizabeth D. Liddy was named Dean of the School of Information Studies (iSchool) in February, 2008. She had previously served as Interim Dean of the iSchool beginning in February, 2007. In January, 2015, she temporarily left the iSchool to serve as Interim Vice Chancellor and Provost. She was appointed to the position by Chancellor Kent Syverud, and served until May, 2016, when she returned to her post at the iSchool.

Prior to her initial appointment as dean, she had spent 20 years as a faculty member and researcher at the iSchool. Liddy has presided over the iSchool during a period of tremendous growth for the school, including the addition of New York State’s first graduate certificate program in data science.

Professionally, Liddy has been elected chair of the Association for Computing Machinery Special Interest Group of Information Retrieval (ACM-SIGIR), is a member of Beta Phi Mu, the library and information studies honor society, and Sigma Xi, the international honor society of scientific and engineering research. Liddy was Chair of the iSchool’s Caucus from 2012 to 2014, an organization that includes over 75 information schools around the globe.

In 1994, Liddy founded and led a software startup company, TextWise, and as CEO grew it to 50 employees, winning the prestigious National Tibbetts Award from U.S. Small Business Administration. She was the founding director of the iSchool’s Center for Natural Language Processing, which advanced the development of human-like language understanding software capabilities for government, commercial, and consumer applications. The holder of eight software patents, Liddy has led 70 research projects, authored more than 110 research papers and given hundreds of conference presentations on her work.

Liddy has taught graduate courses in information retrieval, natural language processing, and data mining, and was the founding faculty advisor of Women in Information Technology (WIT), a student group that supports and mentors female IT students. She is an active member of NCWIT, the National Center for Women in Information Technology, and is involved in the Syracuse community. She is currently serving on the board of the Madden School of Business at Le Moyne College, and was previously a member of the board of the Crouse Health Foundation. She holds a BA in English from Daemen College, and an MS in library science and a Ph.D. in information transfer from the Syracuse University iSchool.


natural language processing, information retrieval, data mining


Liddys main academic focus is natural language processing (NLP), an area of research in which she has been active since her dissertation research that culminated in her award-winning dissertation in 1988, one of the first to prove the utility of NLP for information science. Since then, she has led 65 research projects, all based on the use of NLP for improved information access and analytics. Her research has been funded by a wide range of government agencies as well as commercial enterprises.

She has developed advanced system capabilities for information extraction, information retrieval, data-mining, question-answering, document summarization, cross-language retrieval, web-based retrieval, text-mining and automatic metadata generation. Liddy is the co-inventor on eight patents dealing with NLP and has authored more than 110 research papers and given hundreds of conference presentations on her work.


I enjoy being outdoors, especially kayaking, biking, hiking and cross-country skiing.
