Witnessing potentially traumatic events is linked to poor health

My review paper found consistent links in the literature between witnessing discrimination and elevated risk for depression, anxiety, trauma-related symptoms, poor sleep, and behavioral disorders (e.g., substance use disorder)
My recent empirical work also found that witnessing racial discrimination contributed to trauma symptoms beyond the effect of direct discrimination
Another paper in press found that among U.S. college students, witnessing potentially traumatic on-campus events was linked to increased depression
Exposure to potentially traumatic events is pervasive online. Through funding from The Harvard Center for Population and Development Studies, we found that young adults have distinct cognitive, emotional, and behavioral responses that may underlie mental health symptoms
I have a K23 grant application under review at NIMH that aims to identify mechanistic pathways connecting witnessing distressing online content to depression, anxiety, and PTSD

Our research uncovered that for college students experiencing suicide symptoms during the pandemic, treatment was lower than expected. Past treatment was the biggest predictor of future help-seeking intention
I observed a similar pattern in an older sample of young adults and identified structural (e.g., lack of funds) and attitude (e.g., thinking symptoms were not serious enough for treatment) barriers to help-seeking for suicide symptoms
We also found that sexual minority college students display higher help-seeking willingness than others, signaling a resilience factor
My paper found that college students are likely to rely on blended formal (e.g., psychotherapy) and informal treatment (e.g., self-guided digital apps), suggesting important directions for tailoring support
Through grant applications and empirical work, we are also exploring the role of AI in mental health help seeking

I published a model of anti-racism development in White youth, which includes learning about racism and racial identity, feeling empathy, and engaging in behaviors that counteract racism
In a more recent paper, witnessing racism, high tolerance for distress, and feeling impacted by the social climate predicted more anti-racist behaviors in White young adults during the pandemic
I presented my research about an anti-racism educational program for White families at the Society for Research in Child Development 2025 meeting

Racial disparities in sleep contribute to broad health inequities. I have established links between witnessing discrimination and poor sleep in college students (in press) and young adults
Collaborating with public health researchers, we propose that a societal-level decrease in youths' sense of safety is a social determinant of health disparities. In our publication, we identify a sense of safety as a modifiable cognitive-affective process that can bolster or impede youth well-being
