Daniel Moreira is a Brazilian biologist and biochemist currently working as an MSCA Postdoctoral Fellow at i3S – Instituto de Investigação e Inovação em Saúde, University of Porto, Portugal, hosted in the Glial Cell Biology Lab of Prof. João Relvas. His research focuses on how animals survive in low-oxygen environments — specifically, the molecular and biochemical mechanisms that allow certain species to tolerate conditions that would be lethal to humans.
Daniel completed his BSc in Biological Sciences (2011), MSc (2014), and PhD (2017) in Biochemistry and Molecular Biology at the University of Brasília (UnB), Brazil. His doctoral thesis — Adaptations of Redox Metabolism to Environmental Extremes: Mechanism, Distribution, and Occurrence of the "Preparation for Oxidative Stress" Phenomenon — was awarded the Great Award for Best PhD Thesis in the Life Sciences at UnB. He is now based at i3S full-time through a Marie Skłodowska-Curie Actions Postdoctoral Fellowship (Horizon Europe, grant 101210478).
His current project, URC-Hypoxia — Unlocking the Redox Code, aims to produce the first comprehensive time-domain map of the molecular mechanisms underlying hypoxia tolerance, combining redox biochemistry, transcriptomics, and proteomics in the model insect Tenebrio molitor. More broadly, his research programme spans comparative biochemistry, oxidative stress regulation, the Preparation for Oxidative Stress (POS) theory, and bioactive natural products from amphibians and other organisms. He has published over 50 peer-reviewed papers (15 as first author), with work appearing in journals such as Free Radical Biology and Medicine, Science of the Total Environment, and Proceedings of the Royal Society B. He is a recipient of the Biochemical Society's Inspiration and Resilience Award and is an active mentor, reviewer, and science communicator.
