Research Focus

We study the biology of membraneless organelles (MLOs) in bacteria and use these findings to engineer synthetic MLOs in higher order organisms.

Biomolecular condensate formation by phase separation has emerged as a new principle to explain the dynamic organization of living cells. We have uncovered an essential bacterial MLO, defined by liquid-liquid phase separation of the disordered protein PopZ, that is conserved across the extremely diverse and abundant a-proteobacteria.

  • Our lab is studying the structure, dynamics, and function of PopZ phase separation in the context of adaptation to environmental challenges.
  • We use this knowledge to engineer synthetic MLOs for interrogating properties and function of phase separation in human cell lines, as well as for therapeutic application
