Olga Ortega-Martinez is a Researcher at the Department of Marine Sciences , University of Gothenburg. As an EMBO Fellow , her work focuses on molecular and developmental biology , stem cell behavior , and regeneration mechanisms in marine organisms, particularly echinoderms . Her research explores gene regulatory pathways shared between embryonic development and adult regeneration, with implications for chordate evolution . Institution: University of Gothenburg Department: Marine Sciences Email: olga.ortega-martinez@marine.gu.se Current projects investigate biomineralization and cell lineage regulation in brittlestars ( Amphiura filiformis ), integrating genomics and molecular biology to understand regenerative capacity and environmental stress adaptation . Her group examines how ocean acidification disrupts developmental pathways, linking these findings to global ecological challenges. Scientific contributions include studies on: Brittlestar genome (2024) - Echinoderm regeneration genomics Chondroitin sulfate roles (2017) - Glycobiology in regeneration Environmental stress impacts (2014, 2010) - Ocean acidification effects Marine population genetics (2022, 2023) - Ecotype differentiation Publications span marine molecular biology , regenerative medicine , and environmental genomics . Her work bridges fundamental developmental biology with applied climate change research , using advanced transcriptomic and proteomic techniques to analyze gene expression during regeneration and stress adaptation.
