Jeffrey Scott Vitter is a U.S. computer scientist and academic administrator. Born in 1955 in New Orleans, Vitter has served in several senior higher education administration posts. He is a former chancellor of the University of Mississippi (Ole Miss). He assumed the chancellor position on January 1, 2016. His formal investiture to the chancellorship took place on November 10, 2016, at the University of Mississippi's Oxford Campus., video recording, November 10, 2016

Education Vitter was born and raised in New Orleans, Louisiana. He earned a Bachelor of Science in mathematics with highest honors from the University of Notre Dame in 1977, a Ph.D. in computer science from Stanford University under the supervision of Donald Knuth in 1980 and a master of business administration from Duke University in 2002.

Career From 1980 to 1992, Vitter was a faculty member in the Department of Computer Science at Brown University in Providence, Rhode Island. He moved to Duke University in 1993 as professor and chair of the Department of Computer Science, and as Gilbert, Louis, and Edward Lehrman Professor. From 2002 to 2008, Vitter was the Frederick Hovde Dean of the College of Science at Purdue University in West Lafayette, Indiana.

Vitter served at Texas A&M University in College Station, Texas as provost and executive vice president for academics from 2008 to 2009. He also oversaw A&M's campus in Doha, Qatar. From 2010 to 2015, Vitter was provost and executive vice chancellor and Roy A. Roberts Distinguished Professor at the University of Kansas in Lawrence, Kansas. As provost, Vitter was the chief academic and operations officer for the Lawrence and Edwards campuses.

Vitter spent sabbatical leaves at the Mathematical Sciences Research Institute in Berkeley, CA; INRIA in Rocquencourt, France; Ecole Normale Supérieure in Paris; Bell Laboratories in Murray Hill, New Jersey; Aarhus University in Aarhus, Denmark, and INRIA in Sophia Antipolis, France.

In 2015, Vitter was named as the chancellor of the University of Mississippi in Oxford, Mississippi, starting as chancellor and Distinguished Professor of Computer & Information Science in 2016. One of his first actions was to an advisory committee to address Confederate names and memorials on campus; based on the committee's report, he led efforts to rename or add context to many of these. He also pushed to remove the name of a donor from a university school in response to racist online posts by the donor. Academically, he led the university to attain R1 university status, a classification reflecting a high level of research activity. In 2019, Vitter stepped down as chancellor, returning to a regular faculty position. The Daily Mississippian, the student newspaper, characterized his tenure as chancellor as a time of both significant campus construction and "cultural transition", including efforts to enhance diversity and inclusiveness. He retired in 2020 as Distinguished Professor Emeritus; he continues to work as a consultant and hold an adjunct professorship at Tulane University in New Orleans, Louisiana.

Academic interests Vitter is a computer scientist with over 350 books, journals, and conference publications, primarily on the design and mathematical analysis of algorithms dealing with big data and data science. His Google Scholar h-index is in the 70s, and he is an ISI highly cited researcher. He helped establish the field of I/O algorithms (a.k.a. "external memory algorithms") as a rigorous area of active investigation.J. S.
