Health Informatics covers a large number of research areas and methods including, language technology, machine learning or data science sometimes called Artificial Intelligence, modeling, simulation and information access for systems within the health care sector. The aim of our research is to improve health care by meeting the needs for IT systems at various levels, from county councils and hospitals to small mobile units for the elderly and nursing homes, and to support researchers in health care, medicine and pharmaceutical research by providing tools and techniques to support decision making. Some examples include advanced medical decision support for risk assessment, and simulated environments for rehabilitation of violent offenders.
