Martin has a core competence in particle and fibre toxicology. Martin’s research is focused on the nanoparticle-(mammalian)cell interaction, with a view to determining the mechanistic toxicological, immunological and genotoxic effects that nanoparticles, with varying physico-chemical characteristics, may cause at the cellular level by using advanced, next-level in vitro systems combined with state-of-the-art microscopy and bioanalytical approaches. Special interests include the ability for nanoparticle geometry and surface properties to interfere with the human immune system and bloodstream. Another clear ambition of Martin's research is to create, study and promote alternative in vitro models that mimic in vivo environments, in order to gain a mechanistic understanding of how nanoparticles may, potentially, adversely impact human health. Special focus is also given to creating disease-based in vitro models and the role nanoparticles play in disease onsert and/or exacerbation. Martin has >100 publications within the field of nanotoxicology and the nanoparticle-cell interaction in vitro.
