Sam Guglani talks to Professor Dame Sue Black OBE about her early childhood experiences, how they shaped her future career and about how important her teachers have been to her - and why we have a duty to let others who have changed our lives know the impact they have had on us.

Sue talks about how forensic anthropology is changing, about her work in identifying perpetrators of child sexual abuse and in war crimes investigations and about hope, optimism and how she maintains objectivity when faced with the effects of human cruelty.

“Even in the most awful situations,” she says, “you can find something that says humanity is better than this.”
