Research

• Biomineralization in microalgae
• Formation and control of calcium carbonate and purine crystals, as well as silicate and cellulose
• Characterization of metastable phases and their transformations (e.g., amorphous calcium carbonate = ACC)
• Influence of biological and chemical environmental factors on mineral formation
• Structural characterization of biominerals at the micro- and nanoscale
• X-ray diffractometry (PXRD and Rietveld)
• Spectroscopy and imaging (Raman/IR/ssNMR)
• Cryo-electron microscopy
