Aileen van Leeuwen

M&E Officer and Research Fellow


Aileen van Leeuwen joined ICCT in 2022. Her focus is on Monitoring and Evaluation (M&E) of the impact and implementation of CT and P/CVE programmes, policies and strategies. In this position, Aileen combines her thematic knowledge on CT and P/CVE and the M&E experience she gained at various international NGOs.

Previously, Aileen provided policy research, advice and evaluations to Dutch professionals concerned with (violent) extremism, radicalisation, polarisation and reintegration. She also supported risk assessments of potential (violent) extremists. Additionally, she worked on designing and implementing M&E frameworks for the exiled, Sudanese media house Dabanga, and supported political dialogues between armed groups, governments and international organisations at the Dialogue Advisory Group (DAG). She also co-founded the start-up Acume, which brings academic insights to policy-makers and practitioners, facilitating innovative and evidence-based decision-making. On the side, she is a photographer and founder of the photography project Portraits for People.

Aileen holds an MA in Conflict Studies and Human Rights and a BSc in Interdisciplinary Social Sciences (with honours) from Utrecht University in The Netherlands. Her MA thesis (published as a peer-reviewed article) focused on the reintegration process of ex-paramilitaries in Medellín, Colombia, and was based on 3-month field research and interviews with ex-paramilitaries.
