Marlies was born and raised in Berlin, Germany. As a medical student at the Free University and Humboldt University of Berlin, she performed her M.D. thesis work with Prof. Detlev Ganten at the Max Delbru?ck Center for Molecular Medicine and Max Planck Institute for Molecular Genetics. After her medical residency in Neurology and Internal Medicine, Marlies joined the State University of New York at Stony Brook, where she completed her Ph.D. thesis in the group of Dr. Bruce Stillman at Cold Spring Harbor Laboratory with the discovery of a novel mechanism linking epigenetic silencing and nucleotide metabolism. Motivated by her interest in transcription and chromatin, and the power of unbiased screens, Marlies then joined Dr. Leonard Zon's lab as a postdoctoral fellow at the Department of Stem Cell and Regenerative Biology of Harvard University. There, through a chemical suppressor screen in zebrafish and subsequent genetic, genomic and metabolomic analysis also involving human cell models, she elucidated that a transcriptional program drives erythroid lineage differentiation by instructing critical metabolic activities. Marlies joined the University of Rochester as Assistant Professor of Biomedical Genetics in January 2023. Her lab focuses on the instructive role of metabolism during cell fate decisions in hematopoietic lineage differentiation.


Lineage differentiation depends on gene expression programs that regulate changes in cell fate, including metabolic changes. However, we poorly understand if, when and how metabolism actively promotes lineage specification and differentiation and how gene expression, in turn, adapts to the metabolic state. The Rossmann lab studies hematopoiesis as a paradigm to elucidate the crosstalk between transcription, specific metabolic activities, and the epigenetic landscape during cell fate decisions. We use zebrafish as a powerful genetically tractable vertebrate model that amenable to screening and in-vivo imaging, but also integrate it with mouse and human stem cell differentiation models. We strive to leverage key insights from these studies to elucidate the metabolic origins of a variety of diseases, facilitate novel metabolism-centered differentiation therapies for hematological malignancies, and combat the decline in lymphoid cell production by the aging hematopoietic system.
