About me
I am an Associate Professor (Docent) at Karolinska Institutet, a licensed clinical psychologist, licensed psychotherapist, and specialist in clinical psychology. My work combines clinical research, research leadership, and specialist clinical expertise in psychological trauma and post-traumatic stress disorder (PTSD) and complex PTSD.
Alongside my academic position, I hold a clinical leadership role at the Regional Center for Excellence for PTSD situated at Psykiatri Sydväst where I am responsible for the quality and development of psychological treatments.
I lead several clinical research projects focused on advancing evidence-based PTSD treatment and translating research findings into clinical practice. I am an certified trainer and supervisor in Prolonged Exposure (PE) therapy and serve on the Board of the European Society for Traumatic Stress Studies (ESTSS).
Research
My research focuses on advancing the development, evaluation, and implementation of evidence-based psychological interventions for PTSD and complex PTSD, with a particular emphasis on improving treatment effectiveness, accessibility, and delivery.
I lead several randomized controlled trials investigating innovative approaches to trauma-focused treatment, including intensive Prolonged Exposure (PE), therapist-guided digital interventions, and early psychological interventions following potentially traumatic events. My research spans different clinical populations, including adults, children and adolescents, and individuals with a migrant background.
A central focus of my research is identifying and overcoming barriers to effective PTSD treatment, including patient and therapist avoidance, limited treatment availability, and challenges in implementing evidence-based interventions in routine clinical care. By integrating clinical research with specialist psychiatric services, my work aims to develop scalable, effective, and clinically feasible treatment approaches that can improve PTSD care across different healthcare settings.
Teaching
I have extensive experience in teaching, clinical training, and supervision in psychological trauma, PTSD, and evidence-based trauma-focused treatments. I teach at undergraduate, postgraduate, and specialist levels and provide advanced clinical training for mental health professionals.
As an internationally certified Prolonged Exposure (PE) trainer and supervisor, I deliver specialist training, consultation, and supervision to clinicians and healthcare organizations nationally and internationally, with a particular focus on treatment fidelity, clinical competence, and the implementation of evidence-based PTSD care.

- Swedish Research Council for Health Working Life and Welfare1 January 2024 - 31 December 2027Research problem and specific questionsPost-traumatic stress disorder (PTSD) is a debilitating psychiatric condition strongly linked to subsequent psychiatric and medical problems and increased risk to die by suicide. Evidence based treatment such as prolonged exposure are seldom available in regular care. 60% of patients fail to demonstrate clinically significant symptom change. One reason for the low success rate is that a high proportion of patients drop out of treatment. Hence, there is an urgent need for treatments that can decrease dropout rates and increase availability. A more intensive treatment approach has been suggested to achieve faster recovery rate as well as a decreased dropout rate. Is intensive exposure-based treatment (I-PE) more efficacious than weekly delivered sessions regarding PTSD symptoms, drop out and cost-effectiveness?Data and methodThe main objectives are to investigate long-term efficacy, potential mechanisms of change and cost-effectiveness of intensive exposure-based treatment (I-PE) for PTSD in a randomized controlled trial (N=140) comparing I-PE with weekly delivered exposure-based treatment. Outcome measures will include, but not be limited to, gold-standard clinician rated symptoms of PTSD, dropout rate, speed of recovery, and health economical aspects.Societal relevance and utilizationThe proposed project contributes to Forte’s strategic agenda and UN’s Sustainable Development Goals. There is large gap between need of treatment and supply. I-PE may be a more cost-effective, evidence-based treatment for PTSD that results in a faster recovery rate, decreased dropouts and increased availability of treatment. In addition, it can potentially decrease societal and health care costs through more efficient administration of treatment, reduced waiting times, reduced therapist resources, and less sick leave.Plan for project realizationParticipants will be recruited through referrals to Traumaprogrammet, Psykiatri Sydväst, where a feasibility study (N=35) has showed the intervention and recruitment procedures to be feasible and the treatment to preliminarily be effective. All procedures and treatment have been refined based on interviews with the participants. Clinician and self-administered measures will be used at baseline, during treatment, post-treatment, 1-month (primary endpoint), 6-month, and 12-month follow-up by assessors blinded to treatment allocation. Funding from Forte is sought for three years.
