Abstract  
Online communities are spaces where some people go to engage in meaningful personal and business-related endeavors. One way to increase the quality of individuals’ online experience is through the research, design, and application of interventions. However, prior work has suggested that one-size-fits-all interventions are not suitable. In my research, I study individual-level factors and identity characteristics, that can inform the design of online system affordances and interventions. First, I studied personality characteristics and derived a set of personas that can be used to design future interventions in the domain of online misinformation. Next, I studied clinical indicators of post-traumatic stress disorder on Reddit (/r/ptsd) and provide design implications that can be used to provide improved online experiences for individuals seeking mental health information, as well as novel clinical decision-making tools. In my last study I design, develop, and evaluate a computational intersectional identity framework (CIIF) for use with online communities to describe post authors in terms of their intersectional identity disclosures at scale. The CIIF provides a new intersectional term dictionary, identity detection approach, and a new methodology that can be used to continuously update it for use in intervention design research.
