Uncover the mechanisms of cell differentiation and motility control using Dictyostelium as a model organism
His research group is studying multicellular development and eukaryotic chemotaxis using Dictyostelium as a model organism. Research focus is on the mechanism of Cell Fate Decision by GSK3, PP2A/ B56/PTPA, ZAK and the regulation of Eukaryotic Chemotaxis by regulation of phosphoinositol-(3,4,5)-triphosphate (PIP3).
