We organize online talks aimed at young researchers (master and PhD students, post-docs). This is an opportunity for them to present their work. There are also contributed talks by confirmed researchers.

Chairman: Moustapha Camara (mc.camara@univ-zig.sn)

These online talks are open to all. If you would like to attend, contact the Chairman.
