Our lab is interested: 1) cell size control and the downstream consequences of size dysregulation, and 2) protein self-assembly to form mesoscale structures, including membraneless organelles, the mitotic spindle and signaling complexes. We characterize early development, during which cells rapidly divide without growing, and which contains embryo-specific condensates such as germ granules. Further we investigate diseased cell states, including lung adenocarcinoma, in which cell size homeostasis is lost. To biophysically characterize the principles of protein condensates to form membraneless organelles we use modeling and biochemical reconstitution.

We use interdisciplinary approaches to address fundamental questions in cell and developmental biology. Further we develop new tools and techniques to probe and mechanistically dissect cellular processes. Our toolkit includes imaging and sequence the nascent transcriptome during embryo development, engineered proteins that form synthetic membraneless organelles, microfluidic approaches to encapsulate proteins construction of cell-like compartments for lipid alternatives. Additionally, we have developed optochemical and optogenetic strategies to control protein localization and enzymatic activity ex vivo and within cells. Our model systems include: zebrafish and Xenopus cleavage-stage embryos, mammalian cell culture, and biomimetic synthetic cells. Our philosophy is to understand biology by building it from the bottom-up using minimal sets of components.
