A, B and C) Algae sampling site on the coast of the Valparaíso Region
D, E) Appearance of the algae in its natural habitat
F) Appearance of the algae selected for the experiments
The researcher obtained his Biochemical degree in 2009 and his Doctorate in Biotechnology degree in 2014 at the Universidad de Santiago de Chile.
The research area focuses on the study and potential application of the mechanisms of tolerance and detoxification of hydrocarbons of marine macroalgae to recover coastal areas negatively impacted by human activity.
He is currently carrying out the Fondecyt initiation project 11180189 entitled "Mechanisms of accumulation, tolerance and metabolization of polycyclic aromatic hydrocarbons (PAHs) in the marine alga Ulva lactuca (Chlorophyta)" (three year project 2019-2021). In 2020, the insertion project in the PAI79170105 academy was completed, on which the researcher established his research area at the university (three-year project 2018-2020).
