Vetle Torvik

Associate Professor

PhD, Engineering Science, Louisiana State University

Research focus

Mathematical optimization; computational statistics; text and data mining; literature-based discovery; bioinformatics.


Torvik received degrees in mathematics and operations research and earned his PhD in engineering science from Louisiana State University. He was a research assistant professor in the Department at Psychiatry at the University of Illinois at Chicago before joining the University of Illinois at Urbana-Champaign. He teaches courses on text and data mining, statistical modeling, informetrics, and information processing. His current research addresses problems related to scientific discovery and collaboration using complex models and large-scale bibliographic databases. He has built a suite of bibliographic data mining tools and datasets that are available from ABEL.
