Dr. Arnold’s research centers around identifying key biobehavioral factors that influence alcohol and other substance use within the context of aging. Specifically, her work focuses on 1) understanding how individual differences in emotion regulation and stress reactivity, 2) sociocultural factors, such as norms and discrimination, and 3) pain, such as fear and perception, contribute to substance use behaviors in later life. Dr. Arnold’s current and future work strives to understand inter- and intraindividual variation in these factors among both middle-aged and older adults with particular interest in racial/ethnic and sexual minority populations.
