My research focus is in understanding the development of children’s biobehavioral regulation as it relates to health, academic skills, and adjustment. My research utilizes several measures of child psychophysiology, including neuroendocrine and autonomic nervous system activity, as well as child sleep, assessed using video recordings, actigraphy, and parent report. My recent work is particularly focused on how child regulation is related to adjustment in contexts of risk, including family and socioeconomic adversity.
