Hamilton Sleep and Health Lab

The Hamilton Health Lab is directed by Associate Professor Dr. Nancy Hamilton in the Department of Psychology at the University of Kansas. The lab focuses on research related to sleep, dreaming and nightmares, as they relate to physical and mental health. We are particularly interested in understanding posttrauma nightmares and using that information to develop interventions.

Current Projects

The Hamilton Health Lab investigates various aspects of trauma and sleep through multiple projects. We assess trauma prevalence and its effects on sleep and PTSD in students (STAND), identify triggers for posttrauma nightmares in sexual assault survivors (AT NIGHT), explore how sleep impacts recovery after sexual assault (Project Mindy), analyze emotional content in dreams using AI (The Dream Machine), and develop strategies to improve sleep quality for firefighters (Project Fire).

Student Trauma and Nightmare Development (STAND)

STAND assesses traumatic experiences and posttrauma symptoms among KU students, by examining sex differences in trauma exposure and response, and exploring the impact of sleep on the development of PTSD symptoms.

The Dream Machine

The Dream Machine is a collection of projects designed to use AI technology to understand the emotional content in dreams.

Project Fire

Project Fire is a collection of projects designed to understand the unique sleep problems faced by career and volunteer firefighters and ultimately to develop strategies to improve sleep quality either by changing environmental sources of sleep disturbance or by addressing individual sleep problems.

Project Mindy

Project Mindy aims to understand how sleep changes in the six months following sexual assault to develop interventions that prevent the progression from trauma to PTSD symptoms.

Assessing Triggers of Posttrauma Nightmares

AT Night uses ambulatory assessment and a longitudinal design to identify antecedents of posttrauma nightmares in individuals with trauma-related nightmares from sexual assault.

Things that Go Bump in the Night

This project aims to examine the environmental characteristics associated with negative sleep performance in career fire fighters.

Continuous-RoBERTa, Sentiment Analysis Tools

This project is focused on creating code to analyze dream reports to assess for emotional intensities using pre-trained transformers models.

Examining Cross Diagnostic Arousal Measurements

This project looks to develop and assess metrics of micro-arousal during sleep from polysomnography signals, primarily electroencephalogram.

Nancy Hamilton

My work emphasizes sleep’s role in mental health, health behaviors, and social stress. Currently, I focus on posttrauma nightmares (PTN) and community-engaged projects with fire and rescue services, including developing AI tools for PTN research and exploring the trajectory of sleep symptoms from trauma to treatment.

Garrett Baber

My research interests include the relationship between sleep and emotional health, such as the etiology and treatment of posttraumatic nightmares and other sleep disorders.

Matt Gratton

My research interests are focused on understanding the role of arousability and awareness during sleep, particularly focused on behavioral sleep disorders and obstructive sleep apnea.
