The Barone Laboratory will open doors in March 2024 at the Hopkins Marine Station and is part of the Biology Department of Stanford University.


We explore how variation in cell behaviours that determine the physical properties of tissues contribute to the evolution of development.

Marine embryos help us in our research: meet the sea star and sea urchin embryos

Sea Urchin
Lytechinus pictus
Sea star
Patiria miniata

Although early development of sea star and sea urchin is similar in many ways, there are key differences in their cell and embryonic shapes. For instance, sea urchin embryos are more compact than sea stars' and cell size is more homogenous in the sea star than in the sea urchin. We ask how these differences in embryonic shape affect patterning and cell fate decisions.

Our method of choice is live imaging. It allows us to carefully observe the shape of the whole embryo and the behaviours of individual cells within it.

We test our hypotheses using embryology and biophysics approaches
