THE LEAD
Prof. Dr. Dr. Clare Killikelly
Evidence-based practice, first-hand
As a researcher, Clare is keen to bring up-to-date, evidence-based therapies to my practice. Through her dual role as a researcher and a clinician, she strives to bring my clients the most effective, proven treatments. Her clinical work combines established best-practice interventions with the latest developments from new and emerging areas of research.
What Clare treats
Clare provides assessment and therapeutic intervention in English for stress and anxiety, trauma, depression or low mood, recovery from stroke or brain injury, social anxiety, OCD, support for ASD, loss and grief, and the strain of caring for others.

- Acceptance and Commitment Therapy
- Mindfulness
- Compassion Focused Therapy (CFT)

The research behind the practice
Clare works at the Division of Psychopathology and Clinical Intervention, University of Zurich, where her research group examines the clinical utility and global applicability of the new ICD-11 Prolonged Grief Disorder. Alongside establishing the validity of the new symptom criteria internationally, the group seeks to understand suffering and distress in different communities, in order to develop accessible, culturally informed assessments and interventions.
