Research Interests

Director: Existential Trauma Lab

The Existential Trauma (ET) Lab, housed within the 猎奇重口’s Department of Psychology, focuses on the application of existential theory to better understand potentially traumatic events and responses. Research projects emphasize expanded conceptualizations of trauma and traumatic stress responses. Although clinical conceptualizations of trauma, i.e., PTSD, are often included, we tend to focus on potentially traumatic events (PTEs) and responses that exist on the margins of diagnostic criteria. This involves the examination of, for example, collective and systemic traumas that may be impactful, not necessarily due to a literal threat to one's safety, but because of a threat to one's existential security and ability to maintain meaningful connections to others and the world. The diversity that students and other collaborators bring to the research process is a resource and a strength—I am always happy to merge my interests and skillset, when appropriate, to support specific topics meaningful to my students and colleagues.   

Projects

ACTIVE COLLABORATIONS AND TOPICS OF STUDY

Global Collaboration on Traumatic Stress: The ET lab is an active participant in the . The GC-TS brings together researchers and clinicians from around the world who collaborate on topics of global importance related to cross-cultural experiences of traumatic stress. Lab members are actively involved in GC-TS projects and Dr. Williamson serves as the co-chair for the Climate Change workgroup.

Climate Change: The intersection of climate and mental health is an exciting and emergent line of research in the lab, representing a topical extension and application of previous theoretical and empirical work. Given the uniqueness of climate change as a non-discrete event that creates a cascade of PTEs both within and outside of circumscribed diagnoses, the ET lab is well-equipped to investigate the complexity of this contemporary global issue.

Sexual Violence: Projects explore the existential impact of experiences of and exposure to sexual and gender-based violence, including widespread coverage of the MeToo movement, reproductive coercion and abortion restrictions.

Perpetrator Trauma: This research builds on a developed theory of traumatic dissonance, which describes the socio-cognitive mechanisms responsible for traumatic responses to one's own act of perpetration. This model supports existing research documenting the potential psychological impact of certain acts of perpetration but re-conceptualizes the phenomenon in terms of general existential motivations.
