Lab Director

Prof. Brooke Ammerman is the director of the ASSIST Lab at the University of Notre Dame. She received her B.S. from North Dakota State University, M.A. from University of Northern Iowa, and Ph.D. from Temple University. She is most interested in better understanding the mechanisms underlying non-suicidal self-injury and suicidal thoughts and behaviors, and how to translate what we learn in the laboratory to the “real world.” When not at work, Prof. Ammerman enjoys running, taking photographs, and enjoying the great outdoors. For more information on Prof. Ammerman's research, see her CV.

Graduate Students

Caitlin O'Loughlin is a second year student in the ASSIST Lab. She graduated from Notre Dame with a BA in Psychology and a minor in Business Economics in 2017. After graduation, she completed a year-long post-baccalaureate research fellowship at Drexel University’s Center City Clinic for Behavioral Medicine, where she was the research coordinator for two treatment outcome studies examining the effects of Acceptance and Commitment Therapy (ACT) on various clinical health populations, including people living with HIV and Cystic Fibrosis patients. While at Drexel, Caitlin worked on several projects including a study examining the relationships among cognitive fusion, self-compassion, shame and internalizing symptoms in people living with HIV, as well as a study identifying predictors of dropout from a time-limited psychotherapy program. Caitlin’s research interests broadly focus on suicidality, NSSI, and clinical health psychology. More specifically, she is interested in the relationship between shame and psychological symptoms, as well as exploring the predictors and aftermath of disclosing highly-stigmatized behaviors or diagnoses to others. In her free time, Caitlin enjoys spending time with her family and being outside.

Yeonsoo Park is a second year year student in the ASSIST Lab. He graduated from New York University with a BA in Psychology and earned a MA in Counseling & Clinical Psychology from Sogang University in Seoul, Korea. Yeonsoo’s research interest is in the broad range of self-injurious behaviors (i.e., non-suicidal self-injury, suicide) with a focus on identifying their risk factors. More specifically, he is interested in how emotion and cognition interact to increase one’s risk, and how intrapersonal and cultural factors influence their manifestation. During his free time, Yeonsoo enjoys spending quality time with friends, playing sports, and listening to music.
