Gilbert Habaasa is a Research Degree Student and Researcher in Demography at the London School of Hygiene & Tropical Medicine. His work focuses on mortality dynamics in Sub‑Saharan Africa, with interests in adult mortality, sex differentials, lifespan inequality, and under‑five mortality. He analyses large-scale population datasets including IPUMS census microdata, Demographic and Health Surveys (DHS), and Multiple Indicator Cluster Surveys (MICS) to examine patterns and disparities across diverse African contexts. His research integrates quantitative demographic methods with emerging qualitative insights to deepen the interpretation of mortality trends.

Gilbert is also interested in the strengthening and analytical use of Civil Registration and Vital Statistics (CRVS) systems in low‑ and middle‑income countries. His work explores how CRVS data can complement census and survey sources to improve mortality measurement and generate more reliable evidence for population health.
