She wrote several reports on tax evasion, inequalities and the sharing of wealth in large companies: "I tracked down the most fortunate who do not pay their fair share of tax and who make tax evasion... hounded large multinationals who prefer to pay a few zealous shareholders rather than the vast majority of wage earners who produce wealth." She taught at Sciences Po Paris faculty about human rights. Having practiced swimming in competition, she now plays water polo.
