Evolutionary ecology; demography; epidemiology; statistics; fishing.
My main research interest is human evolutionary demography in preindustrial populations. In my research I use historical demographic data from northern Fennoscandia that contain people practicing traditional subsistence modes as well small-scale agriculture and trading. This data set is accompanied with wealth of information on how those people lived and on their environmental conditions. I also work sporadically with other study systems related to evolutionary psychology, evolutionary medicine and behavioral ecology.
