John Archibald Molecular biologist

John Archibald’s lab uses molecular tools to study the patterns and processes of microbial evolution. Of particular interest is the process of endosymbiosis, whereby one single-celled organism takes up residence inside another. The Archibald lab studies examples of ancient and recently established endosymbiotic mergers in order to reconstruct key events in the evolution of complex (nucleus-containing) life forms.
