She acted as a mentor for the Roma Settlement Elimination Programme of the Ministry of Social Affairs and Labour. She has been consultant to Hungarian policy-makers in areas related to gender-, ethnicity- and class-based inequalities.

In 2014, she co-founded the School of Public Life in Hungary, which aims to improve the country’s democratic culture through education and training for marginalised people and their communities. Mariann is head of educational programmes in the organisation and teaches introductory courses in social inequalities, citizenship rights and social policy in prison facilities, grassroots organisations, as well as the Roma and the refugee programmes of CEU.
