Professor Mark Stitt Mark is a Department Director at the MPIMPP. His research addresses the regulation of central metabolic pathways in plants, especially photosynthesis, starch and sucrose metabolism. His interest in C4 metabolism started when he developed methods to measure metabolite concentration gradients between mesophyll and bundle sheath cells. He has recently refined methods to use stable isotope labeling and liquid chromatography linked with tandem mass spectrometry to gain deeper insights into the path of carbon in both C3 and C4 photosynthesis.
Dr John Lunn John is a Senior Research Scientist at MPIMPP. He has a long-standing interest in understanding how plants determine the fate of carbon fixed during photosynthesis. His current work focuses on the sugar-signalling metabolite, trehalose 6-phosphate. Forward and reverse genetic approaches are combined with transcript, protein and metabolite analyses to identify components of sugar-signalling pathways, with the long term goal of understanding carbon allocation at the whole-plant level.
Dr. Stéphanie Arrivault Stéphanie is currently a postdoc in Mark Stitt’s lab. She gained her PhD in plant molecular biology from the MPIMP where she studied the role of a putative metal transport protein in Arabidopsis. Her research is focused on the elucidation of carbon fluxes in C3 and C4 photosynthesis by use of dynamic 13CO2 labeling coupled with LC-MS/MS quantification.

Dr. Chiara Baccolini is a postdoc in Mark Stitt’s group. She gained her PhD in Biology at the Leibniz University Hannover where she worked on nucleotide catabolism in plant. Her current research focuses on the sugar-signalling molecule trehalose 6-phosphate and its role in plant growth and development. She joins the C4 rice project in August 2021.
