Biografía: 

El investigador obtuvo su título de Bioquímico el año 2009 y su grado de Doctor en Biotecnología en 2014 en la Universidad de Santiago de Chile.

Lineas de Investigación: 

La línea de investigación se centra en el estudio y potencial aplicación de los mecanismos de tolerancia y detoxificación de hidrocarburos de macroalgas marinas. Con el fin de recuperar zonas costeras impactadas negativamente por la actividad humana.

Proyectos: 

Actualmente está llevando a cabo el proyecto Fondecyt de Iniciación 11180189 titulado “Mechanisms of accumulation, tolerance and metabolization of polycyclic aromatic hydrocarbons (PAHs) in the marine alga Ulva lactuca (Chlorophyta)” (proyecto de tres años 2019-2021).

En 2020 se finalizó el proyecto de inserción en la academia PAI79170105 con el que el investigador estableció su línea de investigación en la universidad (proyecto de tres años 2018-2020).
