Our research draws upon principles of fluid dynamics, colloidal science and materials science to study the dynamics of biological systems (fluids, cells, tissues) under flow, upon surfaces and within complex three dimensional geometries. Insights that we gain are applied to the rational design and fabrication of diagnostic, prognostic and therapeutic platforms. A central theme to this research is an exploitation of microfabrication and microfluidics as a route to new device platforms and compositions of materials.
