Our conversation begins with how prolonged exposure to violence shapes a child’s emotional and cognitive development and how trauma manifests differently across age groups. Drawing on his experiences in East Africa andBelfast, Dr McMullen offers a grounded psychological lens on how early trauma becomes embedded in the developing brain—shaping how children view themselves, others and the world.

While his research is rooted in specific regions, such as Uganda and the DRC, his insights reveal something universal: trauma transcends borders. Whether it’s a child in Gulu, Gaza, or East Belfast, the psychological effects of violence are strikingly similar. This generalisability opens up space to explore shared risks and opportunities—especially in long-standing conflict zones like Israel-Palestine, where children live in segregated societies often shaped by inherited fear and mistrust.

We also discuss resilience—what it looks like in children exposed to war, and whether it can be cultivated through education. From integrated schools in Northern Ireland to classroom interventions in Uganda, Dr McMullen shares lessons with relevance far beyond any one context.
