Teaching this semester

PSYC 2025. Abnormal Psychology

An introduction to the phenomenology, etiology, and treatment of mental disorders. Major topics include depression, bipolar disorder, anxiety disorders, obsessive-compulsive disorder, post-traumatic stress disorder, schizophrenia, eating disorders, and personality disorders. Current paradigms for understanding psychopathology, diagnosis and assessment, and research methods specific to clinical psychology also discussed.

PSYC 3026. Psychology of Trauma and Posttraumatic Stress Disorder

Explores the psychological impact of many different types of trauma, including military combat, accidents, interpersonal violence, sexual assault, natural disasters, and childhood physical and sexual abuse. The emphasis is on psychological theories used to explain and treat symptoms associated with posttraumatic stress disorder (PTSD). Covers diagnostic methods, research on prevalence and policy issues, comorbid psychological and medical diagnoses, and social correlates. In addition to exploring the challenges associated with PTSD, addresses mechanisms of positive change following trauma (e.g., posttraumatic growth).

My research focuses on emotion dysregulation in posttraumatic stress disorder (PTSD), as well as the maintenance mechanisms of the disorder. Emotion dysregulation is prevalent in PTSD (and other forms of psychopathology), and as most emotion dysregulation strategies in individuals with PTSD are avoidance based, my focus is on assessing the role of avoidance in PTSD symptom maintenance. I aim to address these questions using a multimodal method of assessment (e.g., self-report, interview, task-based measures) to better understand how and why emotion dysregulation affects those with PSTD, as well as how the disorder is maintained more broadly.
