I am a consultant on ecological engineering, freshwater ecology and water quality. Experience with natural water purification systems like constructed wetlands. Also experience in new sanitation practices and water purification with algae and duckweed.

My whole life I am deeply convinced that we have to change our ways so that we live in harmony with nature and the global ecosystem. If we do not, humanity will not flourish if not parish.

Presently I work on a number of projects involving natural water purification systems that not only purify water, but also generate useful biomass. Also projects involving how we can remodel cities and building to make them more in line with the workings of nature.
