SCIENTIFIC PUBLICATIONS
Dr. Krizan's research team examines how sleep and circadian processes interface with personality and social behavior, especially as applied to legal and investigative contexts. Scientific works span both basic and applied science conducted in the laboratory and the field.
Sleep, Emotions, and Behavior
Basic Science
Sleep is essential for healthy functioning and optimal performance, but we lack understanding about how sleep impacts emotions and behaviors in inter-personal contexts, or how emotions in return influence sleep. To this end, ongoing research aims to clarify causal connections between sleep and socio-emotional functioning.

Individual Differences in Sleep Health
Basic and Applied Science
How long and well people sleep is highly individual as well as reflective of social-structural factors. Ongoing research aims to establish how and why sleep varies as a function of personality differences and social-structural changes (e.g., technology adoption).
