I studied Civil Engineering at Delft University of Technology in The Netherlands from 1992-1999. Since 1999 I´ve been practicing Risk Management specializing in quantitave risk analysis both financial and planning/scheduling. I work with planning experts, but my expertise is the implementation of uncertainty. I use Pertmaster (Primavera Risk Analysis) and think of myself of a senior expert of this tool. I work for large infrastructural projects mainly in The Netherlands.
