Research Interests

My primary research emphasis has been gas exchange in the normal and abnormal lung. Utilizing the inhalation of fluorescent aerosols and the injection of fluorescent microspheres, we take high-resolution measurements of ventilation and blood flow to obtain complete flow maps of the lung.

The correlation between these two flows determines the efficiency of overall pulmonary gas exchange. One research question under investigation is the importance of scale in determining gas exchange efficiency, as both regional ventilation and ventilation have fractal properties. A second focus is the study of mechanisms which determine this matching of flows. A clinical research interest centers around the mechanisms determining exercise limitation in a wide variety of human disease conditions, utilizing the clinical exercise studies performed in the pulmonary diagnostic laboratory.
