Research interests

My main research interests are the fate and effects of synthetic chemicals in the environment, with the aim to formulate general principles of ecotoxicology. This improves environmental risk assessment of chemicals and facilitates sustainable design of chemicals. Typically the research consists of mathematical modelling and laboratory experiments combined with some field work. Currently I'm most interested in these questions:

  • Why do organisms differ in their sensitivity to chemicals?
  • What are the general principles that govern toxicity of different chemicals?
  • How do critical transitions propagate from cells to organisms and ecosystems?
  • How can we improve quantitative in-vitro to in-vivo toxicity extrapolation?

I’m particularly interested in the development of ecotoxicological effect models, for example toxicokinetic-toxicodynamic models. In order to develop, parameterise and test these models I carry out experiments, mostly with aquatic invertebrates. In recent and on-going projects I have investigated pesticides, industrial chemicals, pharmaceuticals and engineered nano-materials. My research has also led to the development of new tools for the risk assessment of chemicals. For example methods for the assessment of time-variable exposure that I developed are currently being applied in the risk assessment of pesticides and more recent work that links in-vitro to in-vivo toxicity data via models has great potential.
