First person – Tom Carruthers

First Person is a series of interviews with the first authors of a selection of papers published in Biology Open, helping early-career researchers promote themselves alongside their papers. Tom Carruthers is first author on ‘ exTREEmaTIME: a method for incorporating uncertainty into divergence time estimates’, published in BiO. Tom conducted the research described in this article while a PhD student in Professor Robert Scotland's lab in the Department of Plant Sciences, University of Oxford. He is now a postdoc in the lab of Dr William Baker at the Royal Botanic Gardens, Kew, working on determining the extent to which large molecular phylogenies provide information about evolutionary history.
