Martin is a biologist interested in studying what plastics and other synthetic agents (e.g., endocrine disrupting chemicals) do to human and ecosystem health. For that he uses state-of-the-art in vitro and in vivo bioassays to characterize the total toxicity of complex samples (e.g., leachates of plastic materials). He also applies effect-directed chemical analysis to identify novel compounds causing the observed toxicity. With this approach he aims at contributing to a more holistic understanding human and environmental exposomes. To achieve this, he is working at the interface of mechanistic toxicology, exposure science, non-target chemical analysis, and environmental health.
