Corry Gellatly is a biologist whose research is broadly in the areas of population biology, evolutionary theory and human social evolution. His PhD thesis was on the population genetics and evolution of the human sex ratio – it put forward an individual selection model for sex ratio evolution, and through analysis of genealogical data, provided empirical evidence for heritability of sex ratio in humans. The study of sex ratio and sex differences in a contemporary and historical context are an important part of Corry's current research, which is focussed on contemporary social and genetic evolution in humans, i.e. evolution that has occurred within the past 1,000 years.
As a visiting researcher with the Social and Economic History research group since 2011 and now an in situ postdoctoral researcher from January 2014 on, Corry has been applying his expertise with web and database technologies to the collation and analysis of historical datasets, including the reconstruction of historical populations from genealogical records.
As part of an NWO funded project examaining the biological and institutional basis of increasing life expectancy in Europe, Corry is working with a number of historical data sources and applying evolutionary theories of ageing to research questions that are of interest to biologists and historians alike, e.g. causes of the demographic transition and increasing life expectancy. He works in collaboration with the Institute for Ageing and Health at Newcastle University.
