Toosin’s research focuses on biomolecules including peptide-, protein-, and polysaccharide-based polymers, which provide a scaffolding for the biominerals, that is, calcium carbonates and phosphates or silica. His current research is on organic (peptide, protein, and DNA) sequences binding to the inorganic materials. Further, he is using several tools to explore preserved protein and DNA in dental plaque (i.e., dental biofilm and calculus) and other artefacts, including ceramics and fossilised shells. He aims to use a multi-omics approach to improve the reconstruction of diets and diseases and evolution in action. His technical skills include biomaterials isolation and purification, organic-inorganic synthetic methods, and characterization (microRaman, AFM, DFS, CFM, FTIR, pyrolysis GCMS, TGA-DSC, XRD, FESEM) as well as in vitro activity assay techniques.
