Carl Barker Postdoctoral Researcher

Carl Barker joined Edge Hill University as an undergraduate on its BSc Biology programme. Following graduation, he worked for two years as a Research Assistant examining potential niche separation in the closely-related British tree species, Tilia cordata and T. platyphyllos (lime trees), before securing a position as a Graduate Teaching Assistant. His PhD research examined a various aspects of the ecology and population genetics of T. cordata. He is currently employed as a postdoctoral researcher exploring the relationship between aging and DNA methylation in lime trees.
