First person – Aitana Manuela Castro Colabianchi

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. Aitana Manuela Castro Colabianchi is first author on ‘Segregation of brain and organizer precursors is differentially regulated by Nodal signaling at blastula stage’, published in BiO. Aitana Manuela conducted the research described in this article while a PhD student in Dr Silvia Liliana Lopez's lab at the Institute for Cell Biology and Neuroscience, University of Buenos Aires. She is now a postdoc in the lab of Dr Lucía Florencia Franchini at INGEBI, 2490 Vuelta de Obligado, Buenos Aires, investigating those mechanisms that first metazoans developed and still have impact in our lives.
