Hello !

I am a PhD Student and I am working on photo-induced modifications in model membranes.

I study the physical transformations induced on giant unilamellar vesicles (GUV) by singlet oxygen species generated at the GUV surface by anchored photosensitive molecules. Lipid peroxidation results for our systems in the production of a significant surface excess that we measure by micropipet aspiration.

I also analyze the evolution of the different mechanical properties of the membrane under illumination.
