My program of research centers on understanding how and for whom treatments work, particularly for adults with transdiagnostic emotion dysregulation. I utilize a multi-method approach, integrating biological indices, multi-informant data sources, and advanced longitudinal modeling to examine mechanisms, moderators, and individual predictors of treatment outcomes. My dissertation research, funded by a Training Fellowship from the Society for Psychophysiological Research and a Doctoral Dissertation Grant from Columbia University, investigated targeted mechanisms in the transdiagnostic treatment of perseverative negative thinking using event-related potentials.
