Sophie G Martin is a Full Professor in the Department of Molecular and Cellular Biology at the University of Geneva, Switzerland. Her research focuses on molecular mechanisms of cell polarization, actin and sterol dynamics, and cell-cell fusion processes using Schizosaccharomyces pombe as a model organism.
- Current research explores TORC1 reactivation during mating, Cdc42 threshold dynamics in fusion decisions, and cross-species actin network imaging
- Leaders the Martin Lab at Geneva, mentoring 14+ students/postdocs including Laura Merlini and Melvin Bérard
Research Highlights:
Through quantitative live-cell imaging, electron microscopy, and proteomics, her lab investigates:
- Coordination of cytoskeletal organization with membrane dynamics
- Phosphoproteomic signaling networks in sexual reproduction
- Actin focus architecture in fusion processes
- Evolutionary conservation of aster formation mechanisms
Recent Publications (2023-2024) reveal key findings about:
- Cdc42 concentration thresholds in mating
- TORC1's dual role in starvation and reproduction
- Arp2/3-dependent endosome shaping
- Novel microscopy methodologies (Cryo-ExM, IntAct-U-ExM)
- Mechanistic parallels between actin and microtubule organization
Collaborations span structural biology, microscopy, and yeast genetics communities, including Marko Kaksonen, Carolyn Bertozzi, and Tim Clausen's group.
