Output

All my publications as a UGent-(co-)author are archived in a more permanent and stable way in our university's institutional archive. You can directly access my page there or use the individual ‘handles’ provided below.

To link to my publications, please use my archive page or these handles; do not link to this page. When citing publications with a doi, also add the handle. These allow everybody to have easy access.

In the list below, I have abbreviated the name of Gert de Cooman (GdC) and myself (EQ). The entries are color-coded: publication, publication with presentation, presentation with (extended) abstract, and other.
