Our lab is interested: 1) cell size control and the downstream consequences of size-dysregulation, and 2) coordinated protein assembly into mesoscale structures, including membraneless organelles, the mitotic spindle and signaling complexes. To investigate the impacts of cell size on cell function, we characterize early embryo development, a period in which cells rapidly divide without growing. Additionally, we are investigating diseased cell states, such as cancer, in which proper cell size homeostasis is lost. To characterize principles that drive the self-assembly of proteins, we focus on scaling and positioning of the mitotic spindle within cleavage stage embryos and in vitro. Additionally we want to understand the properties of proteins that drive their self-assembly and phase separation into membraneless organelles.

We utilize a set of interdisciplinary approaches to address the fundamental questions in cell biology. This strategy requires that we adapt and build new tools, including imaging of transcription during embryo development; microfluidic approaches to encapsulate proteins and cell-free cytoplasmic mixtures inside cell-like compartments in vitro; optochemical dimerizers to control protein localization and enzymatic activity within synthetic cells. Our model systems include: zebrafish and Xenopus cleavage-stage embryos, mammalian cell culture, and synthetic cells. We leverage numerous biochemical approaches extoll the power of bottom-up reconstitution to recapitulate cellular processes ex vivo.
