Drs. Julien Simon: having finished my studies of International and European law at the Radboud University of Nijmegen I lived and worked in various West-African countries for some ten years working in the area of ICT. During those years I was involved in training and capacity building, network development and integration and automation of work processes as well as the development and realisation of communication strategies in order to valorise scientific research. Returning to The Netherlands I started working for the T.M.C. Asser Instituut within the department of Information Technology and Information services. For many years I was able to contribute to the development of valorisation and communication strategies and the carrying out/management of numerous projects in that area. In 2006 I became a member of the Management Team responsible for Operations (including the ICT Department) and later on the Human Resources Department. Since its inception I was involved in the International Crimes Database Project. Over the years I was able to contribute to the development of the project and the acquisition of funds for this important project.

In the current project he was responsible for functional and technical design, Database development, front- and back-end development and integration of third party products.
