The PEP Lab aims to advance research and treatment of psychopathology in adolescents and young adults. Rates of mental health problems, such as depression, anxiety, and suicidal thoughts and behaviors, among youth have risen and remain persistent. In particular, youth from disadvantaged backgrounds are disproportionately impacted and lack access to effective interventions. A common thread across these conditions is that of disruptions in emotional functioning and regulation. Therefore, by studying and intervening on how youth process emotional information, we can develop better etiological and treatment models of psychopathology to alleviate suffering during a crucial developmental period.
