Hilde, from Trinity College Dublin, is a PhD student who is working on dating volcanic ash layers related to Zn/Pb deposits in Ireland. She let me know how her project helps knowing better the timing of ore mineralisation and we chatted about what makes her science communication award-worthy. Ben also tries to speak German with the guest!
