Natalia Castejon holds a Ph.D. in Food Chemistry from the Autonomous University of Madrid (2018). Her Ph.D. thesis primarily focused on the extraction and enzymatic modification of omega-3 oils from novel plants and microalgae using green techniques and environmentally friendly solvents. Afterward, she worked for one year as a post-doctoral researcher at the University of Iceland (2019), where her research dealt with the development of eco-friendly methods to produce natural extracts from seaweeds to be used in cosmetics products. In 2020, she did a postdoctoral stay at the University of Pau and the Adour Region (Anglet, France). Her research aimed to develop alternative greener and more efficient extraction approaches for obtaining bioactive molecules and biomacromolecules from red seaweeds. In 2020, she was awarded the H.P. Kaufmann Award granted by the German Society for Fat Science (DGF). Moreover, in 2020, the AOCS acknowledged her carrier giving her the recognition "Young Scientists to Watch". Recently, she received a 3-year postdoctoral fellowship (2021-2024) from the REinforcing Women In Research (REWIRE) Programme, a Marie Sklodowska Curie Actions co-funded by the University of Vienna and the European Commission. Her project, BioactALGAE, explores for the first time the valorization of microalgal biomass by exhibiting biological activities of produced extracts using a multi-step extraction method implying eco-friendly techniques.
