I am a third year student in Dr. Christopher Cushing’s Pediatric Health Insight Team (PHIT) lab. My primary research interests are in understanding the microtemporal (i.e., moment-to-moment) processes that influence healthy decision-making in youth. My research goals are to better explain the underlying mechanisms that mediate physical activity behaviors. My long-term aim is to translate these findings into personalized clinical interventions (e.g. just-in-time adaptive interventions, N-of-1 RCTs) for youth with chronic health conditions.
