Background and activities
My main research interest is in understanding and describing complex systems, more specifically fluid-structure interactions and interactions between biology and the physical-chemical environment.
I like to work interdisciplinary to promote technology and knowledge transfer between research areas. Most of my work has been within aquaculture, with focus on good fish welfare and environmental effects of fish farming.
Aquaculture systems are complex and dynamic. To fully understand such systems we need to study how (flexible) fish farm components, the surrounding water body, chemical and physical quality of the environment, wild and farmed fish, marine fouling parasites/pathogens, fish farm activities and use of technological solutions interact with each other.
Other fields of interest include planktology, biological and chemical oceanography, integrated aquaculture and scientific method development.
