Lic. in Sociology from the Free University of Brussels (1990), and PhD in Demography and Sociology from the University of Pennsylvania (2006).

I joined LSHTM in the fall of 2012, following post-PhD stints at the University of the Witwatersrand (South Africa) and Princeton University (USA). I am serving as the head of the Population Studies Group since the summer of 2019.

In addition to a long-standing interest in family demography and the demographic impacts of HIV (cf. ALPHA Network), I am currently engaged in a number of projects that are pioneering new solutions to demographic estimation in settings with deficient CRVS. These include the expansion of the sibling survival method for cause-specific adult mortality estimation (a collaboration with Stéphane Helleringer at NYU) and the refinement of indirect estimation techniques for under-five mortality estimation; a multisite study coordinated by Michel Guillot (INED/Univeristy of Pennsylvania).

In 2021, we launched the Rapid Mortality Mobile Phone Surveys (RAMMPS) Consortium. RAMMPS revolves around a mobile phone-based approach to gather mortality data in settings where other mortality surveillance systems are weak or interrupted because of health or other crisis situations. RAMMPS is an international collaborative research initiative with partners at Johns Hopkins University, New York University, UC Louvain and research institutes in each of the countries where the RAMMPS will be fielded (Malawi, Mozambique, Burkina Faso, The Democratic Republic of Congo and Bangladesh).
