Juan J. Pierella Karlusich (Post-doc)
Research
Broadly, I work in the ecology and evolution of ocean microbial communities, with a focus on the functional and taxonomic diversity of phototrophs and nitrogen-fixers. I am using the remarkable resources that Tara Oceans expeditions generated by sampling all major oceanic regions, including meta-omics, high throughput imaging and environmental parameters. My main aim is to provide a framework for understanding the resilience of microbial communities in a changing ocean.
I have previously worked on understanding the role of chloroplast redox modulation of genome-wide responses of crop plants towards drought and pathogens, and in the different tactics that plants, algae and cyanobacteria have evolved to cope with iron deficiency.
In addition to research, I have been involved in teaching and in writing popular science articles.
