Macromolecules rarely operate in isolation inside cells. At any given time, the average protein is part of a complex of over 10 macromolecules, and these supramolecular complexes are in turn embedded in intricate networks inside cells. We are broadly interested in revealing the structure and function of macromolecular complexes in their natural environment at the highest possible resolution in order to reveal their structural dynamics and interactions. We call it bringing structure to cellular biology.
We have a strong focus on building tools for quantitative cell biology, using cryo-electron microscopy and tomography, cell biophysics, computational analysis, and integrative modeling. This potent combination allows us to look at macromolecular complexes in their native environment and derive their structure, context, and interaction partners.
Our biological focus is on the study of the nuclear periphery, as nuclear biology remains one of the most exciting challenges in the cell, and it is uncharted territory structurally. Our thrust in this area includes projects such as: the structural dynamics of the yeast nuclear pore complex, the mechanical communication between the cytoskeleton and the nucleus, and the molecular architecture of the genome and its association to the nuclear envelope. We also collaborate with different laboratories to open windows into various cellular events. These projects tend to have a translational component, and include studying the inner life of bacteria and studying the effects of LRRK2 in Parkinson’s disease, among others.
