Jakob is one of the pioneers in applying modern psychometric theories to health status measurement. His research focuses on development of item banks, modern psychometric methods, and software applications for psychometric analyses and computerized assessment. In collaboration with Dr. Ware through the past 10 years, Jakob has led the development of numerous computerized adaptive tests of generic and disease-specific health outcomes, including DYNHA^®, the first commercialized CAT system for assessing health outcomes. To date, Jakob has published 12 peer-reviewed papers about item bank and CAT construction, one of which won the 2004 Article of the Year Award from the International Society for Quality of Life Research (ISOQOL). Jakob was a senior research fellow at the Danish National Institute of Occupational Health and has previously worked at the University of Copenhagen, where he received a gold medal for research on Quality of Life and HIV.
