Research Focus
My research focuses on performing noninvasive measurements in humans, using established techniques and novel functional magnetic resonance imaging (MRI) techniques, to study lung physiology in health and disease.
Head-down Tilt and Graded Saline Infusion
Thus far we have used such techniques to elucidate changes in the heterogeneity of lung mechanics, pulmonary blood flow, and lung density that occur during the early stages of pulmonary interstitial edema. We utilize either 30-degree head-down tilt or graded saline infusion to provoke an increase in fluid content of the lung, and consequently the early stages of pulmonary interstitial edema. Our study has relevance for providing (1) a basic understanding of how the early stages of pulmonary interstitial edema affects lung function, and (2) models that can be used for studies related to the diagnosis and treatment of subclinical edema.
The Effects of Gravity on the Lung
The lung is strongly influenced by gravity; therefore studying lung physiology in the absence of gravity has been of great interest for our lab for many years. The NASA Lab has been directly involved in almost all of the studies of lung function performed in space since the Shuttle began flying. These have included studies on SLS-1 (STS-40), SLS-2 (STS-58), LMS (STS-78), Neurolab (STS-90), D-2 (STS-55), ST-95 and STS-107. My work in this area has primarily involved ground studies using novel MRI techniques to study the effects of gravity on the lung.
Chronic Obstructive Pulmonary Disease (COPD)
We are now in a position to utilize the sophisticated MRI techniques we have developed to quantify the spatial pattern of density, blood flow, and ventilation in the human lung in vivo. Use of these MRI techniques, combined with the multiple inert gas elimination technique (MIGET) and computed tomography (CT) imaging, could provide insight into how the different phenotypes of COPD are mechanistically different. A better understanding of the underlying physiology in the different phenotypes of COPD may allow for the identification of patients that would most benefit from current therapies, as well as provide pathways for future therapies.
