Jonas Schöley is a statistical demographer studying mortality across the life course at the Max Planck Institute for Demographic Research. His current research interests are in Perinatal Demography, i.e. population dynamics surrounding birth, mortality crises & displacement, conformal prediction & uncertainty quantification, and the role of discontinuities in demographic modeling. His dissertation under James Vaupel elucidated the role of mortality selection and the birth transition in shaping early life age patterns of mortality. During the COVID-19 pandemic Schöley published timely international estimates of life expectancy deficits and excess mortality. He is currently a member of the WHO technical advisory group on global excess mortality estimation. Jonas is passionate about data visualization and has created the R library tricolore which is used across fields to map compositional data. He is the creator of demoscapes.org, a digital atlas of Lexis surfaces.
