Researcher biography

I have received my PhD in organic electronics from the University of Bordeaux, France, in 2016. Since then, I have been working as postdoctoral research fellow at Queensland Brain Institute, the University of Queensland in Australia, carrying out research in organic electronics, experimental physics, materials science, optics and neuroscience.

My main research project is focused on applying organic electronics to neuroscience, particularly to optogenetic studies involving light manipulation of neurons. Within this framework, I published, inter alia, 3 research articles demonstrating successful detection and stimulation of neuronal activity using organic photodetectors (OPDs) and organic light-emitting diodes (OLEDs), and currently work on implantable organic neural probes. On a more fundamental level, I have pioneered the discovery of a novel method of light detection in OPDs, as well as contributed to the development of ultra-efficient infrared OPDs, reflected in many high-impact research articles.

My other areas of research also covers the development of smart wearable sensors for optimization of therapy in patients with Parkinson's Disease and other neurological movement disorders.
