:wave: I’m Josselin Lefèvre, a PhD student at Thermo Fisher Scientific and LIGM.

In my doctoral research, I’m addressing challenges related to Hierarchical Segmentation under Memory Constraint. I am also interested in interactive segmentation. In this way, it will be possible to extend the application of the hierarchical toolbox to the processing of large images.

I obtained an engineering degree in computer science at ESIEE Paris with honors with a specialization in Image Processing.
