PhD, Engineering Science, Louisiana State
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.

This project examines the impact of different research funding structures on the training of future scientists, particularly graduate students and postdoctoral fellows, and the impact on their subsequent outcomes. Our proposed research begins by examining the way in which research (and most training) is funded and done. We classify projects by whether they are large or small scale (by funding size); multiple researchers; or multiple institutions.
