David Lydon-Staley, PhD is an Assistant Professor and the principal investigator of the Addiction, Health, and Adolescence (AHA!) Lab at the Annenberg School for Communication. His research examines the unfolding of human behavior over short timescales (e.g., moment-to-moment, day-to-day) during the course of everyday life. With this attention to short-term dynamics in behavior, his research focuses on substance use, emotion regulation, and curiosity across the lifespan. He makes use of functional Magnetic Resonance Imaging (fMRI), experimental laboratory paradigms, and experience sampling methodologies coupled with intensive-longitudinal data and network analysis techniques. Current projects include a NIDA-funded examination of smoking withdrawal symptom dynamics during periods of smoking satiety and smoking abstinence in daily cigarette smokers.
