Research Interests

After graduating from Biochemistry at the University of Chile, I completed an MSc (Res) in Environmental Biochemistry (University of Chile) looking at the genes involved in toxin production in Dinoflagellates. My PhD (funded by a Chancellor's International scholarship) and current research have focused in understanding the molecular mechanisms of phage resistance in marine Synechococcusunder the supervision of Prof. David Scanlan.

Marine Synechococcus andProchlorococcus are widely distributed in the world's ocean, significantly contributing up to the 50% of global primary production. Phage lysis, as well as grazing by eukaryotic protists, play central roles as the major biotic causes of mortality. Synechococcus populations show no extinction, suggesting high rates of production counteract this mortality, or that specific phage resistance and prey-selectivity mechanisms exist. My research has been dedicated to understand these interactions, for which physiological characterisation and whole genome sequencing of several phage-resistant Synechococcus mutants are being carried out. This will give important new insights into key processes affecting trophic dynamics in the oceans.
