Current Responsibility

Martijn is a consulting actuary in the Amsterdam office of Milliman. He joined the firm in 2009, and mainly works on Solvency II related projects.

Currently, he is working on the preparation for IFRS 17 at one of the biggest non-life insurers in the Netherlands. As part of this assignment, he is involved in making accounting policy choices. Besides, he helps in the translation of technical requirements implied by the IFRS 17 Standard into practical solutions.

Next to this, he is currently working on the development of an internal market risk model for Solvency II purposes at another large insurance company. This project is in its final stages, and therefore consists mainly of fine-tuning of the model and explaining all results produced by the model. Martijn was also involved in the design, testing, documentation and implementation of this model.


Prior to this, he developed and validated internal premium and reserve risk models and models to determine the risk on disability insurance products (incidence and recovery risk). He also has extensive knowledge of longevity risk modelling, and he has extensive experience in multiple software packages and programming languages.

Before joining Milliman he worked as an analyst in J.P. Morgan's London office for more than two years. He was based in the insurance structured finance team and worked on the development of structured securities for insurance companies for the purpose of capital raising and risk management.
