Dr Pedro Murúa

Molecular Algal Pathologist

I am an aquaculture engineer, reformed in the direction of algal pathology.

I employ microscopy, molecular and culture approaches to diagnose new algal diseases and to describe novel defence mechanisms in brown and red algae. I use NGS/Omics to refine this knowledge towards a molecular level.

Contact details:

My research interests centre on various aspects of seaweed biology, lately mostly directed towards algal/pathogens interactions:

  • >Description of novel algal pathogens, which includes the characterization of life cycles, dissemination and infection strategies, nutrition and development.
  • >Epidemiological aspects in brown algal populations, using brown algal endophytes-kelps as model pathosystems.
  • >Immunity of brown/red algae, starting from pathogen recognition to neutralization. In this sense, lately I have been dissecting a plethora of autophagy processes used by both host and pathogen, which can subverted towards the benefit of the opposite counterpart.

As a phycopathology less-related matter, I often collaborate with Chilean phycologists in areas related to kelp conservation biology, ecology and aquaculture.
