Rik subsequently worked at Exprimo from 2007-2015 as senior consultant, hugely expanding his modelling and simulation skills, running over 20 full-scale projects for a range of clients with applications in scaling adult to paediatric PK and PK/PD, tumour growth modelling, adverse event and effect modelling using repeated ordered categorical data, viral dynamics modelling, modelling repeated daily seizure counts in epilepsy, and naturally numerous population pharmacokinetic projects. He is author and co-author of over 170 publications, including a number of original research articles in the field of PK/PD modelling. Rik has been actively involved in organising the PAGE meeting since 1996, and additionally develops tools to aid in automatic report generation. Rik lives in The Netherlands.
