Erik Koffijberg is an associate professor and the chair of the Health Technology and Services Research Department at the University of Twente. He holds a MSc in Technical Computer Science and obtained his PhD in the field of Health Technology Assessment (2008). He worked at the University Medical Centre Utrecht, The Netherlands, from 2004-2015 before joining HTSR in 2015. His research interests relate to the use of simulation models to assess the expected impact of innovations in healthcare, with a focus on the evaluation and optimization of using novel diagnostic tests in oncology and cardiovascular disease. In this context he utilizes patient-level simulation models to reflect patient heterogeneity, metamodeling methods to optimize target outcomes, and value of information analysis to inform decision making. In the context of early health technology assessment, he is interested in applying minimal modeling value of information approaches to support research prioritization decisions. He is also a member of the ISPOR Task Force on Emerging Good Practices for Value of Information analysis.
