What we do

Deepen our knowledge of living biological matter

We aim to elucidate the laws of physics that underlie the dynamic spatiotemporal organization of life into molecules, cells and tissues. Our focus is to bring fundamental physics to biology for the purpose of understanding and solving biological questions.

Our research is enabled by merging theory and experiment and driven by a collaborative atmosphere in Geneva between University and partner research laboratories.

Our approach: vision & mission

We seek to understand living matter as a self-organizing and active form of soft condensed matter — combining quantitative experiments with theory to explain how biological order emerges, is maintained, and adapts — from single molecules to whole organisms.

Groups

Gonzalez-Gaitan Lab — Biophysics and Cell Biology of Signaling

Gonzalez-Gaitan Lab — Biophysics and Cell Biology of Signaling

We want to understand in physical and molecular terms how cells talk to each other during development. This means our research is highly interdisciplinary: physics, cell biology, molecular biology, biochemistry, genetics... Indeed some of us in the lab are biologists, other physicists, chemists, engineers or mathematicians.

Kruse Group — Organization of cells and tissues

Kruse Group — Organization of cells and tissues

Our aim is to understand collective phenomena in living cells and tissues. To this end we use methods and concepts from theoretical physics and nonlinear dynamics to study specific systems preferentially in collaboration with experimental colleagues. From the point of view of physics, a major challenge lies in treating systems out of thermodynamic equilibrium that play a role in the context of vital biological processes and have an evolutionary history. The description and analysis of these different aspects requires the development of new tools and approaches.

Martin Lab — Cell polarity and fusion

Martin Lab — Cell polarity and fusion

The Martin lab studies the processes of cell polarization and cell-cell fusion, with a particular interest in actin cytoskeleton and membranes. We use a combination of quantitative advanced live and super-resolution imaging for quantitative measurements, as well as genetic and biochemical tools in yeast. A current focus is to understand mechanisms of actin aster formation for vesicle clustering and plasma membrane fusion during cell-cell fusion.
