Current Research Activities
My current activities cover analytical and physico-chemical research on experimental, but also theoretical and numerical aspects of the electrokinetics and hydrodynamics in porous media, with emphasis on separation science. The investigated materials are patterned microchannels used, e.g., as integrated preconcentration units in microfluidic devices, or particulate adsorbents and monoliths confined by (non)cylindrical separation channels employed in nano- and microchip liquid chromatography and electrochromatography.
The approach followed by my group is to investigate closely related research topics with an increasing complexity with the goal of achieving a thorough understanding of phenomena relevant to hydrodynamic dispersion and analyte enrichment, migration, and retention. This comprises the reconstruction of the morphology of monoliths and confined particulate beds, as well as the characterization of the involved surfaces and interfaces, the transient and stationary dynamics of the fluid flow fields, as well as resulting hydrodynamic dispersion. We combine experimental chromatographic methods with direct imaging techniques and advanced numerical simulation approaches (and high-performane computing) for complementary identification and analysis of the underlying key transport phenomena. Gained knowledge on how microscopic structural details and mesoscopic interrelations affect molecular transport allows us to better analyze, understand, and optimize separations observed on a macroscopic scale.
