My research focuses on typical and atypical emotion regulation development, examining the ways that cultural contexts shape emotion regulation, and how early adversity, structural racism and social determinants of health may “get under the

skin” to confer risk and resilience for developmental psychopathology and health disparities, especially among community of color and children of immigrants. As a first-generation college, immigrant, and scholar from the BIPOC community, my career goal is to use this knowledge to promote cultural diversity and inclusion, to inform policy that aims to reduce social inequalities and advance health equity, and to optimize “sensitive window” of preventive interventions. 

I’m the director of the D.A.N.C.E. (Development, Affective Neuroscience, Culture and Environment) Lab studying cultural diversity, children and adolescents’ mental health and the developing brain using a bioecological framework. My lab employs a variety of methods, including the use of longitudinal design, cross-cultural and behavioral experiments, ecological momentary assessment, neuroendocrine assays (cortisol), and neuroimaging tools (fNIRS, EEG/ERP and fMRI). 

Our current funded projects include first integrating the fields of social epidemiology, cultural and developmental psychology, and neuroscience to elucidate the bioecological and developmental pathways linking structural racism and neighborhood inequalities to risk for developing stress-related mental health problems, including both substance use and mood disorders, among adolescents. Second, we are interested to better understand different features (e.g., type, timing, chronicity, appraisal) of stressors that individuals with marginalized identities exposed to in their daily life, and their intergenerational consequences on children’s cognitive and socio-emotional development. Third, we examine how contexts and cultural diversity influence the development of executive function and emotion regulation.
