First person – Julien Pernier

First Person is a series of interviews with the first authors of a selection of papers published in Journal of Cell Science, helping early-career researchers promote themselves alongside their papers. Julien Pernier is first author on ‘Myosin 1b flattens and prunes branched actin filaments’, published in JCS. Julien conducted the research described in this article while a postdoc in Patricia Bassereau's lab at the Institut Curie, Paris, France. He is now a postdoc in the lab of Christophe Le Clainche at the Institute for Integrative Biology of the Cell (I2BC), Gif-sur-Yvette, France, investigating the roles of actin-binding proteins in actin network dynamics and organization.
