Research Interests
Main scope of my work is the root structure and impacts of environmental factors on it, as well as structural aspects of metal uptake and (hyper)-accumulation. The focus is on root apoplastic barriers and their relation with metal uptake using fluorescence microscopy (widefield epi-fluorescence), brightfield microscopy (conventional/digital, up-right/inverted), confocal microscopy (LSCM), electron microscopy (SEM, TEM, EDAX) as well as image processing and analysis (LIM, Lucia, ImageJ, WinRhizo).

My work at Institute of Chemistry is dedicated to microstructural aspects of plant development and the effect of galactoglucomannan oligosaccharides (biologically active substances derived from plant cell walls) on growth processes and defense reactions against Cd toxicity.
