My research explores how social experiences shape the brain and influence our responses to stress. Social behaviour is essential for survival: it helps us recognize danger, form bonds, care for others, and recover from adversity. Supportive relationships can reduce distress and promote recovery, whereas isolation and negative experiences can increase vulnerability to mental illness. Yet we still know little about how the brain recognizes another person’s emotional state and transforms that information into an appropriate response.
My research shows that these social processes have deep evolutionary roots. I identified oxytocin, a chemical involved in social bonding, as a regulator of shared fear. I also discovered brain cells that help individuals rapidly determine whether others are safe or threatening. Together, these findings provide insight into how the brain uses social information to guide behaviour.
My laboratory uses modern approaches to study the brain and behaviour as social interactions unfold. I investigate why social support is more effective for some individuals or under certain circumstances, and whether neuromodulators can promote supportive social behaviour. Ultimately, my research aims to explain how supportive relationships build resilience and inspire new approaches to recovery following trauma and chronic stress.
