Professor
Professor Tatjana Hildebrandt leads the Plant Metabolic Biochemistry Lab at the Institute for Plant Sciences, University of Cologne, where she serves as Principal Investigator within the Cluster of Excellence on Plant Sciences (CEPLAS) and TRR 341 "Plant Ecological Genetics." Her research group investigates plant amino acid metabolism with particular focus on cysteine pathways, mitochondrial function, and metabolic adaptations to environmental stress. Her research program spans four main areas: (1) Amino acid metabolic pathways with emphasis on catabolic processes; (2) Metabolic plasticity during abiotic stress conditions including drought, hypoxia, and energy deficiency; (3) Metabolic interactions between plants and microbes; and (4) Amino acid sensing mechanisms including post-translational modifications like persulfidation. Her group employs biochemical, proteomic, and metabolomic approaches to unravel these complex processes. Analysis of her recent publications reveals a strong focus on cysteine metabolism, mitochondrial function during germination, and the role of amino acids in stress signaling. Her work bridges fundamental plant biochemistry with potential applications in improving crop resilience. Her research consistently appears in high-impact journals including Plant Physiology, Journal of Experimental Botany, and Trends in Biochemical Sciences. Her laboratory currently includes multiple PhD students and postdoctoral researchers working on projects related to amino acid metabolism in Arabidopsis and Lupinus albus. She actively collaborates with researchers across Europe through CEPLAS and the International Max Planck Research School (IMPRS).
