I am interested in designing and using light sensitive molecules to image the dynamics of the brain. With dedicated optical tools, ranging from imaging technologies to nanoparticles, photoactivatable molecules and fluorescent protein based biosensors, I aim to decipher molecular interactions taking place in the brain, in particular in the context of learning and memory.
Current Project: Ultrabright Fluorescent Organic Nanoparticles for Deep Tissue Imaging
The objective of the NanoFUNC project is to develop all-organic nanoparticles that are bright, stable, small, versatile, targetable to a structure of interest and spectrally relevant in order to perform live super-resolution imaging in deep brain tissue.

During my first postdoc, I used the CRISPR-Cas9 technology to generate a knock-in animal bearing a point mutation in the TIAM1 protein to prevent its interaction with CaMKII, a major molecular player in Learning and Memory.
I also worked on the development of FRET-FLIM sensors to probe the molecular cascades involved in structural synaptic plasticity.

During my PhD, I developped a red pH sensitive biosensor to perform dual colour imaging of endocytosis as well as a combined patch-clamp, imaging and photoactivation paradigm to study the mechanism of action of dynamin, its interaction partners and its precise timming of GTP hydrolysis.

During my PhD, I developped a novel imaging paradigm based on the ppH assay to visualise single endocytic vesicle formation in neurons.
I could, among others, monitor the kinetics and localisation of AMPAR internalisation during inducion of Long Term Depression (LTD).
