Research In Profile
Daniel Keir's integrative cardiorespiratory research lab studies how the cardiovascular, respiratory, sympathetic and muscle metabolic systems respond, interact, and adapt to environments, activities, and conditions that challenge oxygen availability and carbon dioxide removal in health, chronic disease and across the lifespan. Of specific interest are integrative physiological responses to exercise, hypoxia (low O2), hypercapnia (high CO2), and their combination.

Graduate Student Opportunities
Research objectives are to discover and explain mechanisms of human physiology and to apply this knowledge to understand and correct illness using strategies that optimize physical performance and health. Four key areas of interest are:
- Elucidation of mechanisms associated with circulatory, respiratory and metabolic control in health and their dysregulation in chronic disease
- Understanding of how these control systems respond to acute and chronic exercise interventions in both healthy and diseased states
- Design of individualized exercise training strategies that improve performance and reduce disease risk in the lives of young and older adults and chronic disease patients in whom exercise intolerance is a major symptom
- Advancing aerobic exercise assessment, prescription, and training practices
