H. (Hal) Caswell

Hal Caswell serves as Professor of Mathematical Demography and Ecology at the Institute for Biodiversity and Ecosystem Dynamics within the Faculty of Science, University of Amsterdam. His research integrates advanced mathematical frameworks with demographic and ecological theory to address complex population dynamics across human and non-human species.

His primary research domains include mathematical demography, ecological modeling, population dynamics, kinship demography, demographic sensitivity analysis, and lifetime reproductive output. Caswell specializes in developing formal models that quantify individual stochasticity, heterogeneity, and variance decomposition in demographic outcomes, with particular emphasis on kinship structures and longevity patterns.

Analysis of his 2014-2021 publications reveals consistent methodological innovation in matrix population models, stochastic demography, and kinship dynamics. Key thematic threads include time-varying demographic rates in kinship systems, multi-state health longevity modeling, variance decomposition in reproductive output, and applications of hyperstate modeling to conservation biology.

Scientific recognition includes:

• ERC Advanced Grant (FORMKIN) for "Formal Demography of Kinship and Family"

Caswell leads major collaborative initiatives including the COMPADRE plant matrix database project and ERC-funded kinship research. His work demonstrates significant translational impact, with applications ranging from sperm whale conservation after environmental disasters to policy-relevant sensitivity analyses of population projections. Current research extends demographic state spaces through hyperstate modeling while maintaining rigorous mathematical foundations.

He maintains active international collaborations evidenced by co-authored publications across ecology and demography journals, with recent work focusing on integrating multiple health states in longevity models and advancing formal kinship theory through time-varying demographic frameworks.
