Research Overview

The research interests of our group are focused on developing novel separation and sample handling components for microfluidic (Lab-on-a-Chip; μTAS) devices and then using these devices to solve interesting bioanalytical problems with special emphasis in the areas of protein separations (proteomics) and single cell analysis. This research is multidisciplinary in nature drawing upon knowledge in the fields of chemistry, physics, engineering, cell biology, and biochemistry.
