Brief Bio: After finishing my PhD in Santiago, Chile, I went to Bonn, Germany to do a Postdoc with Dr. Andreas J Meyer. Throughout this work, I have combined my interest in functional genomics with an ever-growing fascination for redox biology. In the Chemical Signalling lab, we are using genetically encoded fluorescent sensors targeted to different subcellular compartments and use them as tools to – almost literally – ‘shed light’ on different aspects of plant thiol redox biology and other physiological parameters. From this work, we learned that the importance of chloroplasts for modifying the redox state in other parts of the cell is outstanding, particularly when plants experience photo-oxidative stress.
