Welcome to the Evolutionary demography group on stage-and-age-structured biodemography.
Our focus is on developing and advancing demographic methods and theories in stage- and age-structured populations rooted in Markov chain theories. We aim at scaling individual level stage dynamics to population level processes. In particular we are interested in how we can interpret variability in individual fitness components with respect to the evolution of life histories, and ecological and evolutionary demographic dynamics.
Besides this more theoretical work we explore evolution and maintenance of phenotypic variability using a microfluidic device to collect individual level demographic data on E. coli. The experimental system is also used to directly test and further advance demographic theories in constant and stochastic environments.
