Lectures are academic presentations at conferences or speeches and trainings at special meetings on a particular topic (the latter often for a broad audience). The academic lectures are mostly in english; the others more in Dutch (occasionally in French). Powerpoint slides provide textual evidence of the lectures; they are saved in pdf files, with loss of the animation that several crucial slides incorporate.

Main lectures over the period 2000-2006 are posted in one map. Lectures since 2007 are posted by year.

For lectures on demand, organizers have to pay a modest fee + costs, in order to avoid abuse of my time. When you want to organize a lecture please contact me well in advance.

Voor lezingen op aanvraag moeten organisatoren een remgeld + kosten betalen, vooral bedoeld om het aantal lezingen te beperken en zo mijn tijd te vrijwaren voor wetenschappelijk onderzoek. Het is best tijdig contact op te nemen om een datum vast te leggen.
