Rate My Professor Marc Kirschner

A biochemist by training with a strong interest in applying mathematics and physical principles to biology, Kirschner's laboratory investigates biological organization in space and time. His contributions span embryology, cell organization, and cell cycle regulation, including the discovery of the Anaphase Promoting Complex responsible for ubiquitin-mediated degradation of cyclin during mitosis. Current research focuses on cell size control using novel biophysical methods to identify molecular mechanisms; ubiquitin-mediated protein degradation, particularly transcription factor turnover and the cell's degradome; and gene expression in early development through comparative transcriptomics in Xenopus, sturgeon, and Saccoglossus, alongside single-cell analysis and post-translational modifications. He co-authored seminal books Cells, Embryos, and Evolution (Blackwell, 1997) and The Plausibility of Life: Resolving Darwin’s Dilemma (Yale University Press, 2005) with John Gerhart. Kirschner's honors include election as Foreign Member of the Royal Society of London and Academia Europaea in 1999, the E.B. Wilson Medal—the American Society for Cell Biology’s highest honor—in 2003, and membership in the National Academy of Sciences and the American Academy of Arts and Sciences. His quantitative approaches have shaped systems biology, developmental biology, cell biology, and evolutionary biology.
