My research is concerned with the relations between stress, emotions, and cognition, by studying the effects of early life stress (e.g. childhood maltreatment), trauma, and acute stress. The stress hormone cortisol plays a central role in these studies, as well as its supposed antithesis –oxytocin-, also known as ‘the love hormone’. I make use of pharmacological manipulations, information on genetic polymorphisms, and study the role of stress in epigenetic patterns and in the immune system. The role of stress in processing and regulating emotional information is studied with experimental research in the lab, but also in clinical practice. For example, I examine emotion recognition, empathy, attention to emotions, and memory for emotional information in both healthy samples as well as in children and adults with stress-related disorders. With this research I hope to give more insight into the underlying physiological processes that play a role in both healthy and disturbed emotion regulation, as well as the role of stressful circumstances on these processes.
