I am a developmental and health disparities scholar interested in understanding the roles of social, psychological, and biological factors associated with health disparities. My research program examines how social factors create disparities in health through complex biopsychosocial mechanisms. I am especially interested in the intersectionality between life course socioeconomic status (SES) and race as critical social factors that differentiate access to gain and accumulate resources that promote health and avoid diseases. In addition, my research examines the impact of social stratifications on psychological factors implicated in health disparities through the lens of the daily stress process. Daily stressors are minor day-to-day challenges associated with immediate psychological and physiological impacts. Poor psychological and physiological response to daily stressor exposure is a robust predictor for long-term major health problems. One major pathway that links the daily stress process to disease is accelerated aging, an important biological marker for multiple chronic diseases for which there are known SES and racial disparities. In my works, I examine accelerated aging through multiple physiological pathways, including gene expression and epigenetic modification, inflammation, metabolic syndrome, and disease-specific pathways (i.e., accelerated renal aging).
