Sandra played a pivotal role in the development of the ground-breaking duty of vigilance legislation that was adopted in France in March 2017 after 5 years of intensive advocacy work. She also regularly engages constructively with and provides expert advice and submissions to various stakeholders, including the French government, and therefore took an active participation in the development of the French National Action Plan on Business and Human Rights. Sandra has been representing Sherpa in several national and international networks such as the French CSR Forum, the European Coalition for Corporate Justice and OECD Watch.

With over twenty years of experience and decade in defending and protecting victims of economics crimes, fighting impunity, and advocating and implementing for changes of legal frameworks, Sandra is frequently invited to speak at high-level events around the world, such as the UN Forum on Business and Human Rights and OECD Global Forum on Responsible Business Conduct.
