First Person is a series of interviews with the first authors of a selection of papers published in Biology Open, helping researchers promote themselves alongside their papers. Gonzalo Quiroga-Artigas is first author on ‘ Storage cell proliferation during somatic growth establishes that tardigrades are not eutelic organisms’, published in BiO. Gonzalo is a postdoc in the lab of María Moriel-Carretero at Centre de Recherche en Biologie cellulaire de Montpellier (CRBM), Université de Montpellier, France, delving into the genetic factors that influence the extremophile abilities of tardigrades.
