Our group is interested in the dynamics of living systems, from the motion of biomolecules (proteins, nucleic acids, lipids) to that of cells themselves. Ultimately, we are trying to answer the question: How do living cells reconcile constant molecular noise with exquisite organization and agency?
We use fluorescence methods to quantify molecular and cellular dynamics, complemented by structural studies with neutron & x-ray scattering. Our research also has a strong computational component, where we develop image analysis algorithms and perform simulations. We work with a number of model biological systems, from in vitro reconstituted systems to live organisms.

Our research is interdisciplinary by design and draws from different fields, in particular: soft condensed matter physics, optics, cellular & molecular biology, and chemical engineering. We manage this by learning new things every day, and closely working with awesome collaborators.
Asking the right questions is both important and difficult. In our group, we aspire to tackle questions that are relevant to biology, while looking for some of the universality and simplicity offered by physics models. Ultimately, our work is driven by curiosity and wonder at the way living organisms function.
Cooperation, companionship, and respect are encouraged and expected of every member of our group, and should be extended to everyone, no matter their identity, appearance or background.
