Team members of my research group GERME are regularly requested to intervene in the media. We try to accomodate as much as we can, as we understand we work on topical issues. If you are a journalist and cannot reach us directly, try the press service of ULB (they can, if needed, perhaps provide you with cellular phone numbers). They can most probably make an assessment if we are able to intervene on a particular topic. They can also suggest other colleagues.
