Stephanie also has experience developing materials for sustainable energy storage devices.

  • Dr Stephen Brown

    Senior Chemist

    Stephen completed his MSci at the University of Cambridge, with a part III project on Novel battery materials. He then achieved his PhD at the University of Warwick, specialising in the photochemistry of molecular metal oxides. This research led to a postdoctoral partnership with Johnson Matthey on novel catalytic materials.

  • Dr Daniel Hervitz

    Senior Chemist

    Daniel obtained his MSc in Chemistry from the Weizmann Institute of Science, where he investigated the self-assembly of the biopolymer silk in the presence of metal nanoparticles. He then completed his PhD at the University of Glasgow, where his research focused on the automated discovery of functional nanomaterials with unique optical signatures and catalytic behaviour. Alongside his academic research, Daniel has over three years of industrial R&D experience in the pharmaceutical and medical aesthetics sectors.
