Today was the culmination of Zaid’s PhD journey, when he successfully defended his thesis on the use of gold nanoparticles to probe the mechanism of action of a peptide that inhibits ‘flu virus infectivity. Though he approached his viva with trepidation, his beaming face afterwards told a different story. The usual smattering of corrections, a paper already up on Bioarxiv ready to submit for peer review and another to put up on Bioarxiv, and in a few weeks he will be truly done, with a CV to match.
