Research Interests

My current research focuses on mechanisms and interventions for stress-related responses, especially vasovagal reactions. Other areas of research include mechanisms and interventions (e.g., cognitive-behavioural) for anxiety, pain, depression, as well as the recruitment and retention of blood donors. I am a Fellow at Wolfson College, a Chartered Psychologist (British Psychological Society), and a registered Clinical Psychologist (HCPC).
