Trauma Research from International Perspectives (TRIP) Lab

The Trauma Research from International Perspectives (TRIP) Lab is run by Dr. Nuwan Jayawickreme, whose research interests includes the intersection of contextual factors, trauma, and mental health, with particular emphasis on understanding how context shapes the experience, assessment, and treatment of psychological distress in war-affected and displaced populations. His research examines context-specific variations in reactions to trauma and chronic stress, particularly in communities affected by ethnic conflict and civil strife, with extensive work conducted in Sri Lankan, Rwandan, and other international contexts.

Trained as a clinical psychologist with specialized expertise in evidence-based treatments for trauma and anxiety disorders, Dr. Jayawickreme's clinical background informs his research approach. He earned his Ph.D. in Clinical Psychology from the University of Pennsylvania, completed his predoctoral internship at Montefiore Medical Center, and received extensive specialized training during his seven years at the Center for the Treatment and Study of Anxiety at the University of Pennsylvania School of Medicine. His clinical expertise includes evidence-based treatments for posttraumatic stress disorder (PTSD), obsessive compulsive disorder (OCD), social phobia, generalized anxiety disorder, and depression, with particular specialization in Prolonged Exposure Therapy for PTSD. Dr. Jayawickreme mentors graduate students in developing as practitioners-scholars who can contribute to context-appropriate clinical practice and research. Students in the TRIP lab have opportunities to engage in all aspects of the research process, from study design and data collection to data analysis using R to manuscript preparation and conference presentations.

The TRIP lab’s research program is driven by the understanding that a complete picture of human distress—and the most effective approaches to assessment and intervention—requires consideration not only of biology and psychology, but also of context. The lab addresses critical questions about how suffering is described, disclosed, and categorized across different contexts, and examines the implications for developing contextually valid assessment tools and interventions. Through innovative methodological approaches including network analysis, mixed-method designs, and measurement validation studies, the lab aims to bridge the gap between Western psychological models and the lived experiences of diverse populations affected by trauma.

The TRIP lab seeks to develop evidence-based approaches that are both scientifically rigorous and context-appropriate, with the ultimate goal of improving mental health services for underserved and marginalized populations globally. The lab emphasizes community-engaged research that involves collaboration with local partners and aims to produce findings that can be directly applied to improve the lives of trauma survivors and their communities.
