معرفی
Prof. Dr. Robert Ernst is a leading researcher at the Center for Molecular Signaling (PZMS), Saarland University, where he heads the Medical Biochemistry & Molecular Biology group. His work focuses on understanding how biological membranes maintain their identity and functionality through dynamic protein-lipid interactions, with particular emphasis on endoplasmic reticulum (ER) stress response and membrane homeostasis.
- Academic appointments: Professor, Saarland University
- Key research areas: Membrane biogenesis, Lipid metabolism, Protein folding stress, Cellular adaptation mechanisms
- Funding: ERC Consolidator Grant (MemDense project), SFB 1027, Volkswagen Foundation
Prof. Ernst's laboratory employs interdisciplinary approaches combining genetics, biochemistry, biophysics, and computational modeling to investigate membrane property sensors that control organelle identity and cellular resilience during stress, aging, and metabolic diseases.
Scientific contributions include discovering novel mechanisms of lipid bilayer stress sensing via transmembrane domains (e.g., IRE1, PERK), establishing homeoviscous adaptation in eukaryotes, and developing innovative technologies like MemPrep for organellar membrane isolation. His work has significant implications for type II diabetes, neurodegenerative disorders, and secretory cell pathologies.
Current research directions explore how membrane protein crowding and aberrant lipid compositions trigger chronic ER stress, aiming to develop membrane-targeted therapies for metabolic diseases.
Training: Leads a vibrant research team with multiple PhD and MD students, including Jona Causemann, Aamna Jain, Alexandra Cogan, Konstancja Porzycka, and Sören Eggers.
