Dr. Mahoney joined the UNM Psychology Department in the Fall of 2025. He completed his doctoral training in clinical psychology at Idaho State University with specialized training in experimental methodology within the context of behavioral economics (i.e., impulsive choice and risk-taking). Dr. Mahoney completed his predoctoral clinical internship at Geisinger Medical Center in Danville, PA as a Behavioral Medicine Intern. His research focuses on identifying risk, maintenance, and protective factors for the symptoms and diagnosis of posttraumatic stress disorder (PTSD) and substance use disorders (SUDs) among women following exposure to interpersonal violence (i.e., sexual violence, intimate partner violence [IPV], community violence) and among men following exposure to combat trauma through (1) experimental, (2) prospective, and (3) qualitative studies. The intention is to investigate these processes to inform, enhance, and develop evidence-based assessments and treatments for PTSD and comorbid SUDs.

Shantel Horne is a third-year M.A. student and graduated with her B.A. from UCCS in 2023 double majoring in psychology and dance. She joined Dr. Mahoney’s Mixed Methods Promoting Wellness and Recovery Lab (MPWR) in Fall 2021 as an undergraduate research assistant and matriculated to the M.A. in clinical psychology program in 2023. Under the direction of Dr. Mahoney, she completed her undergraduate honors thesis on associations between trauma-related shame, PTSD, and health risk behaviors among women interpersonal trauma survivors. Her populations of interest include women and LGBTQ+ individuals who have experienced interpersonal trauma. Through research and clinical practice, she hopes to improve evidence-based practice and interventions for these populations while exploring emerging approaches such as dance and movement therapy. She is also interested in coping mechanisms, co-occurring PTSD and substance use, the impact trauma-related psychopathology may have on interpersonal relationships, trauma-related shame, and dismantling intersectional barriers to service-seeking among trauma-exposed populations.

Ellie McLane is a Clinical Trauma M.A. student at the University of Colorado Colorado Springs (UCCS). She graduated with her B.A. in Psychology with a minor in Sociology from UCCS in 2024. As an undergraduate she worked with Dr. Diana Selmeczy to conduct her honor’s thesis on the role of active help-seeking in supporting memory and Dr. Kristen Rudd to complete an independent project on how intergenerational trauma impacts children’s executive functioning development. As a master’s student, she has pursued several independent projects under Dr. Mahoney, including her thesis which investigates the role of emotional invalidation in predicting emotion dysregulation and psychosocial functioning in adults exposed to intimate partner violence during childhood. Broadly, she aims to support women and children survivors of intimate partner violence, sexual assault, and/or childhood maltreatment through mixed method and community-engaged approaches to inform prevention, intervention, and policy efforts. Additionally, she hopes to emphasize marginalized perspectives in her work to increase access to care and treatment efficacy within diverse populations. In her free time, Ellie volunteers at a local domestic violence non-profit, consumes copious amounts of media, and meanders about with her dog.
