Research Interests


Dr. Hoyniak’s research focuses on the development of sleep problems in early childhood, exploring how early sleep problems and chronodisruption contribute to later risk for both internalizing and externalizing psychopathology. She uses a combination of psychophysiological (e.g., actigraphy, polysomnography, EEG/ERP) and observational (both in-lab and in-home) data collection in her research.
