Research
I am particularly interest in how the diverse phototrophs have been able to colonize a huge variety of habitats, focusing in their adaptation/acclimation of the photosynthetic machinery and redox metabolism.

During my PhD in Argentina, I studied the tactics that plants, algae and cyanobacteria have evolved to cope with iron deficiency and other environmental hardships. Next, in a postdoctoral stay, I focused in the role of chloroplast redox status in the modulation of plant responses towards drought and pathogens.

In my current postdoctoral position, I am using the remarkable resources that Tara Oceans consortium obtained from samples from all major oceanic regions, which includes metabarcodes, metagenomes, metatranscriptomes, physiological determinations and environmental parameters. My main aim is to get insights into the phytoplankton adaptation/acclimation strategies towards the environment both at the biochemical and physiological levels.
