The last years as a project leader soil remediation at the foundation for soil remediation at Dutch Railways (SBNS). In my whole professional career i always took on the hardest, most complex and innovative projects, like: the first dutch direct push injection with substrate (shockload treatment) for biological degradation and zero emission green in-situ remediation techniques.

I participated in committees, am an experienced speaker at conferences and lguest lecturing at Utrecht University for the course Environmental hydrogeology (since 2009),  and this year 2013 for two phase flow phenomena.
