We have been using technical scientific evidence to assist criminal prosecutions for only about 160 years. Over that time, some of the areas of forensic science have remained essentially unchanged, while others have been revolutionised. What hasn’t changed is the need to communicate the meaning of traces recovered from people and places, and what their analysis means within the context of a case and there in lies the ultimate science communication challenge. The speaker: Professor Niamh Nic Daeid is an award winning forensic scientist and analytical chemist.
