Raul Herranz was awarded a Ph.D. in Biochemistry (molecular evolution, UAM, Spain/ Supervisor Prof. Marco, 2004), including his first spaceflight experiments as a Ph.D. student (Drosophila GENE/AGEING experiments in the Spanish Soyuz Cervantes Mission, 2003). Raul Herranz worked as a post-Doc in several EU ground simulation labs, mainly at the European Space Agency (ESTEC, The Netherlands/ Supervisor Dr. van Loon, 2008) on LDC biological validation. Then, he joined the PCNPµG lab in Spain (CSIC, Spain/ Supervisor Dr. Medina) as a transcriptomics expert, focused on the overall transcriptional effects of suboptimal spaceflight environments. He has been the coordinator of several ESA and United Nations ground simulation projects, Co-I in the ESA/NASA largest Arabidopsis plant biology experiment on the ISS (SEEDLING GROWTH), and was invited as an expert for UN, ESA, and NASA (GENELAB) working groups. Today, he is the European Coordinator of the ESA-funded Space Omics Topical Team and International Standards for Space Omics Processing (ISSOP, https://issop.space/space-omics-topical-team/)
