Rate My Professor Christof Osman

Prof. Dr. Christof Osman is a professor in Cell and Developmental Biology in the Faculty of Biology at Ludwig-Maximilians-Universität München (LMU), leading the Osman Lab as Principal Investigator at the Biozentrum, Großhaderner Str. 2, 82152 Planegg-Martinsried. The lab's research centers on the maintenance and inheritance of mitochondrial DNA (mtDNA), exploring mtDNA organization and inheritance, copy number regulation, and genome quality control in eukaryotic cells. Using budding yeast Saccharomyces cerevisiae, they investigate mechanisms ensuring mtDNA integrity across generations and distribution within the mitochondrial network to supply mtDNA-encoded proteins essential for cellular energy production. Disruptions in these processes contribute to human diseases, ageing, and altered stem cell homeostasis. Techniques include quantitative live-cell imaging, microfluidics, flow cytometry, genetic screens, proteomics, mass spectrometry, computational image analysis, and mathematical modeling.

Prior to his position at LMU, Osman was a postdoctoral researcher at the University of California, San Francisco. His influential publications include "Making heads or tails of phospholipids in mitochondria" (Journal of Cell Biology, 2011, 774 citations), "The conserved GTPase Gem1 regulates endoplasmic reticulum–mitochondria connections" (PNAS, 2011, 414 citations), "ER-associated mitochondrial division links the distribution of mitochondria and mitochondrial DNA in yeast" (eLife, 2013, 386 citations), "Integrity of the yeast mitochondrial genome, but not its distribution and inheritance, relies on mitochondrial fission and fusion" (PNAS, 2015), "Cristae-dependent quality control of the mitochondrial genome" (Science Advances, 2021), "Two mitochondrial HMG-box proteins, Cim1 and Abf2, antagonistically regulate mtDNA copy number in Saccharomyces cerevisiae" (Nucleic Acids Research, 2023), and recent works such as "Real-time assessment of mitochondrial DNA heteroplasmy dynamics at the single-cell level" (EMBO Journal, 2024) and "Local mitochondrial physiology defined by mtDNA quality guides purifying selection" (PLoS Genetics, 2026). With over 3,500 citations and research interests in cell biology, Osman's work has profoundly impacted the understanding of mitochondrial function and genome stability. He serves as a speaker and board member of the Graduate School Life Science Munich (LSM).
