About Stacy

Environmental Exercise Physiologist and Nutrition Scientist specializing in sex differences of heat and/or altitude stress, recovery, genetics, and nutrition  to moderate adaptive responses for performance.

Researching and applying practical sport science to elite professional athletes: Implementing specific cooling and heat adaptation strategies, hydration practices, and overall nutrition to improve performance outcomes and overall health.

Researching and applying modifications of elite athletic practices to obese sedentary individuals; improving exercise tolerance and overall clinical outcomes.

Author of ROAR: "Women are not small men. Stop eating and training like one. Because most nutrition products and training plans are designed for men, it s no wonder that so many female athletes struggle to reach their full potential. ROAR is a comprehensive, physiology-based nutrition and training guide specifically designed for active women. This book teaches you everything you need to know to adapt your nutrition, hydration, and training to your unique physiology so you can work with, rather than against, your female physiology."- Rodale Publishing

Research Interests

Exercise physiological and nutrition science research, focussing specifically on stressors (heat, hydration, hypoxia) and sex differences. Major physiological systems of interest are fluid balance, thermoregulation, epigenetics, neuro-endocrine interactions, and non-pharmaceutical interventions to promote adaptations and health. Major modulating factors of interest are fitness, sex differences, and high performance.
