My laboratory aims to develop an understanding of the interrelationships between the mechanical and physicochemical behavior of biological systems. The main thrust of this research involves investigations of the pulmonary system. It is my intent to use this understanding to help, either directly or indirectly, the development of improved therapies for pulmonary disease. At present, this research focuses on investigations of interfacial phenomena and transport processes relevant to pulmonary disorders. These investigations require the study of surface-tension-gradient-driven (Marangoni) convection, capillarity, physicochemical hydrodynamics, viscous flows, fluid/flexible-boundary interactions and convection-diffusion transport. In addition, I have developed a recent interest in environmental research related to the influence of mechanical stress on cells. These studies focus on identifying the fluid stress field exerted on adherent cells, which may have an impact on mechanotransduction, cell adhesion or bacterial migration through porous media.
