Hello! I am Irene Xu (pronunciation) and I use they/them pronouns. I am a PhD student in the Clinical Psychology Program at the University of Notre Dame. I work with Dr. Brooke Ammerman at the Affect, Suicide, Self-Injury, and Social Triggers (ASSIST) Lab. My research is oriented around understanding the transition from suicidal ideation to suicidal behaviors, especially the distal and proximal cognitive and affective factors involved in the decision making process.


Some of the questions that my research tries to answer are:

To answer these questions, I employ a wide range of methods, including cross-sectional, longitudinal, and ecological momentary study designs. See my recent projects here.
I’m also interested in are disseminating scientific findings in accessible ways and implementing scalable interventions in socially disadvantaged communities. If you share similar interests and would like to collaborate, please feel free to reach out.
