Our Science

Illuminating Cellular Architecture

We are interested in describing and understanding how human cells are built as ecosystems of molecular machines. We are motivated by how this will help characterizing fundamental mechanisms in physiology and diseases, but also by the process of “reverse engineering” a cell - understanding the details of how it is built to be able to predictably tune its properties and behavior.

To start, we are asking: Where are all the proteins in a cell localized, and how do they interact with each other? For this, we develop and deploy a variety of technologies to “illuminate” proteins and manipulate them:

  • We specialize in the development of scalable CRISPR gene editing methods to create genome-scale libraries of fluorescently labeled cell lines.
  • We build software and hardware automation to streamline the design, execution and analysis of our experiments.
  • We use high-throughput live cell fluorescence microscopy to map protein localization in space and time.
  • We use proteomics mass-spectrometry to profile protein-protein interactions and delineate functional networks.

Our goal is to build open datasets, software and protocols for the entire community to use and explore.
