Prof. Dr. Guido Grossmann serves as Head of the Institute of Cell and Interaction Biology at Heinrich Heine University Düsseldorf (HHU), joining CEPLAS (Cluster of Excellence on Plant Sciences) in October 2020. His research program investigates biological interactions from protein-level organization to organism-level symbioses, with particular focus on plant cell dynamics and root-microbe relationships. His academic journey includes: Doctoral research with Widmar Tanner at University of Regensburg studying plasma membrane organization EMBO postdoctoral fellowship at Carnegie Institution for Science in Stanford with Wolf Frommer and David Ehrhardt Independent research group leadership at Centre for Organismal Studies, Heidelberg University (2013-2020) Grossmann's laboratory specializes in developing advanced imaging technologies for plant science, most notably pioneering the RootChip microfluidic platform that enables quantitative microscopy of metabolite dynamics in living plant roots. His research explores how biological systems develop functionalities beyond the sum of their parts, from signaling clusters of membrane proteins regulating cellular growth to root-soil microbe interactions shaping diverse microenvironments. The lab develops soil-inspired cultivation devices for high-resolution imaging of root colonization processes and investigates cell polarization, growth regulation, and intercellular communication in plant roots. Analysis of his publication record reveals consistent innovation in plant imaging technologies alongside fundamental discoveries in root biology, calcium signaling, and plant stress responses. His work bridges theoretical plant biology with practical technological applications, particularly through the development of microfluidic systems that enable precise environmental control for plant studies.

Dr. Philipp Denninger serves as a Group Leader at the Chair of Plant Systems Biology within the TUM School of Life Sciences at Technical University of Munich. Appointed in July 2019, he leads an independent research group focused on plant cell polarity mechanisms under the supervision of Prof. Dr. Claus Schwechheimer. His habilitation process in Plant Cell Biology began in March 2022, marking his progression toward a professorial qualification in the German academic system. Dr. Denninger's research centers on understanding cell polarity and signal transduction in plants, particularly investigating the RhoGTPases (ROP) and their activating guanine nucleotide exchange factors (ROPGEFs). His laboratory employs model systems including Arabidopsis thaliana , Marchantia polymorpha , and Zea mays to study pollen tube growth, cell division, and other polarization events. The group utilizes advanced techniques such as confocal microscopy, image analysis, and quantitative protein-protein interaction studies (MST, FRET) to unravel the spatiotemporal composition of ROP signaling complexes during polar growth. Analysis of Dr. Denninger's publication record reveals a consistent focus on ROP signaling mechanisms across multiple plant developmental contexts. His work demonstrates how specific ROPGEFs establish polar membrane domains that drive processes like pollen germination and root hair outgrowth. The research trajectory shows progression from identifying individual ROPGEF functions to understanding the dynamic repositioning of polarity domains and the negative regulation of polar growth pathways. 2019: Otto Schmeil Award from the Schmeil Foundation Heidelberg for an excellent dissertation 2013: Master's Prize from the Biochemistry Center Regensburg 2012: DAAD scholarship for research at Carnegie Institution of Science, Stanford University Dr. Denninger's laboratory operates within the Chair of Plant Systems Biology, collaborating with international research groups across Europe and North America. His research program integrates in vivo imaging approaches with in vitro biochemical techniques to address fundamental questions about how plants establish and maintain cellular polarity during development. Current projects focus on determining how polarity domain positions are established and how uncontrolled polar growth is regulated to ensure normal plant development.
