Johan Junkka
I am a historical demographer at the Centre for Demographic and Ageing Research, Umeå University. My current research integrates social‐network analysis with longitudinal population data to examine demographic transitions, climate-related vulnerability, health inequalities, and disability across the life course. Working at the intersection of social history, epidemiology, and quantitative sociology, I combine advanced statistical methods in R with interdisciplinary theory to understand how changing social and environmental contexts shape population health and family dynamics over time.
