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.

Research Projects

Workforce Training: A Quasi-Experimental Approach Using the Effects of Research Funding

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.

Analysis of academic activity patterns in academic literature

The project team will work on extracting key concepts from scholarly publications and explore techniques for building a taxonomy of extracted concepts by leveraging open knowledge bases (e.g., Wikipedia). The outcome of this process will be evaluated for various science and technology knowledge platform-based analysis services. The techniques, which reduce semantic ambiguity, will analyze conceptual novelty and expertise of researchers / research institutes across time, leading to a better understanding of the evolution of scientific domains in a scholarly community. The research will also lead to the development of open source tools to allow this research work to be replicated.
