In 2016-2017, I was chair of two inaugural ICCBA committees: the Training Committee and the Professional Standards Advisory Committee.

With reform of the legal aid policy ongoing, it is critical that you elect those who understand the realities of working here. I have worked on ICC legal aid issues for over five years and can advise the Executive Council on representing your interests resolutely and strategically in reform discussions. Furthermore, I would listen to your views on the process of how counsel is selected and appointed with a view that the ICCBA discuss these with the Registry. And lastly, I would advocate building a better long-term funding model for the ICCBA to ensure its future viability. Counsel and support staff can have confidence in me because I have over 13 years' experience at international criminal tribunals, including as staff, counsel, and support staff (ICC, ICTY, ICTR, ECCC, and SCSL). I have also served on the Executive Council and Counsel Support Staff Committee of the ICCBA.
