I am working as a statistics and information science professor at the University of Leuven.
My research is located at the Leuven Institute for Research on Information Systems (LIRIS) and focuses on the intersections of Information Science, Statistics,
Software Engineering, Education, and Statistical Decision Making/Support.
One of my pet projects involves innovative, statistical Web Technologies and Applications for the purpose of reproducible, scientific research and collaborative, academic education.
In particular my work focuses primarily on Compendium Technologies, Reproducible Statistical Computing, and associated Meta Databases.
Here are a few projects I am currently working on:
- early detection of Alzheimer's Disease based on digital biomarkers
- reproducible & collaborative writing (actually I think of this as a part of "reproducible computing")
- constructivist, educational technology (Computer Assisted Learning and Technology Enhanced Learning)
- applied statistics (incl. reproducible statistical computing, modelling, and analysis)
- cloud computing applications for medical decision making purposes (diagnosis, monitoring, and research)
- software & database design, engineering, and development
- technology acceptance, usability and evaluation of Information Systems
- educational & research technology
- automated Big Data Analytics
In summary, I am interested in multidisciplinary, scientific questions from (almost) any field that can be studied through
solid, statistical research and innovative information technology.
