Biography

I am an NPP postdoctoral fellow at JPL/Caltech. I received my PhD in space sciences at the University of Liège with a focus on instrumentation for high-contrast imaging. My current research focuses on applying metasurfaces and more generally microstructured optics to coronagraphic applications.
