My research focuses on the analysis of biopolymer granules from traceless materials GmbH using nuclear magnetic resonance (NMR) techniques. The aim is to develop a fast, non-destructive quality control method and contribute to a better understanding of biopolymer aging mechanisms. The study involves relaxometry and diffusometry measurements to analyze differences in molecular mobility between various samples. The results will be correlated with reference methods to evaluate the potential of NMR for material characterization.

My research focuses on the experimental investigation of fluid flow in complex geometries using Magnetic Resonance Imaging (MRI) velocimetry. The aim is to characterize flow behavior and obtain spatially resolved velocity fields through non-invasive measurements. The study involves 
investigating flow patterns in porous structures, under varying flow conditions. Xanthan  solutions at different concentrations will be used to investigate shear-thinning flow behavior and examine the influence of concentration-dependent rheological properties on local viscosity. The acquired MRI data will be processed and analyzed to provide a better understanding of non-Newtonian fluid dynamics in complex geometries and assess the potential of MRI velocimetry for characterizing complex fluid flows

My research focuses on investigating wall effects in three-dimensional (3D) gas-solid fluidized bed hydrodynamics, with an emphasis on understanding the impact of fluidized bed diameter on bubble and particle behaviour. This includes the detailed characterization of bubble properties such as size, rise velocity, and spatial distribution, as well as particle velocities using Magnetic Resonance Imaging (MRI). A systematic experimental study will be conducted across multiple bed sizes with different particles at various superficial gas velocities to understand how wall effects alter hydrodynamic behaviour. These findings aim to develop an empirical correlation to predict bubble size as a function of bed diameter, addressing a critical gap in existing literature where most correlations neglect the significant influence of bed geometry.
