Healing Through Movement — Empowerment for the Mind and Body

Research scientist and educator investigating how exercise, sleep, and autonomic regulation shape cardiovascular and mental health, with a special focus on PTSD.

Portrait of Dr. Melissa McGranahan

About

I am a researcher focused on autonomic physiology, exercise interventions, sleep health, and risk for cardiovascular disease. My work integrates clinical assessment, physiological monitoring, and translational research to improve outcomes for Veterans and trauma‑exposed populations.

Research

Current interests and active projects.

Autonomic Regulation

Sympathetic Activity & Cardiovascular Risk

Examining links between MSNA, blood pressure variability, and downstream vascular responsiveness in PTSD.

Sleep & Mental Health

Sleep Disturbance & PTSD

Characterizing how sleep features contribute to autonomic imbalance and symptom severity.

Exercise Physiology

Cardiorespiratory Fitness as a Modifier

Testing whether CRF buffers stress reactivity and improves autonomic balance.
