My research interests lie in the fields of development microeconomics, in particular gender, conflicts and agricultural production.
I am currently the Project Investigator in charge of the randomized impact evaluation of the Sahel Women Empowerment and Demographic Dividend (SWEDD) initiative in Mali, a women's empowerment project. Gender-related, focusing on mothers, is another randomized impact evaluation of a parental training program in Nepal I am in charge of - toghether with two other colleagues at Paris-Dauphine - that aims at improving early childhood development. I also have a special interest in social norms and attitudes, how to measure them and their inter-generational transmission. Together with Mary Di Santolo (Uni Dauphine), we are assessing the impact of reservation quotas for women in India and the transmission of gender social norms. At the cross-roads between conflict and gender, I coordinate a research project on the mesurement of attitudes about GBV and towards authoritarian regimes in collaboration with an international and interdisciplinary network of researchers, funded by IRD with a 5-year research grant GDRI MOV (Mesurer et Observer les Violences). Together with Sikandra Kurdi (IFPRI) we are assessing the impact of the current civil conflict in Yemen on trust and cooperativeness measured with a lab-in-the-field conducted among people participating in the Social Fund for Development program. Recently, we also began a randomized impact evaluation of the SFD Cash-for-Work program in Yemen.
Previously, during my PhD, I have been investigating agricultural production investment decisions of farmers and technology knowledge diffusion in rural Uganda with the East Africa Dairy Development project initiative.
I enjoy teaching Public Policies in Developing countreis and Development Micro-Econometrics to second year Master students, as well as Micro-econometrics, Stata and Gender Economics to first year Master students at Dauphine.
