“My research themes are centred on redox biology, stress signalling and metabolism. I aim to improve our understanding of cross-organelle communication during stress acclimation, predominantly using the unicellular model alga Chlamydomonas reinhardtii. Another focus is on desiccation tolerance in seeds and algae, and how redox changes in the desiccated state influence metabolism upon rehydration. I also strive to increase our knowledge on roles of seed microbiota and cross-kingdom redox signalling.”
