Hydra cell aggregates after 24 hours (top) show gene expression for new organizing centers, and 96 hours later have more clearly defined bodies. The blue marks cells that are producing molecules to mark the “head”.

I am a PhD candidate studying jellyfish development and evolution at Brown University. I've participated in numerous research expeditions, studying jellies all over the world, from Africa to the abyss. I am currently studying the beautiful mauve stinger jellies, found in the Mediterranean, and the ghostly Atlantic stinging nettles found on the US east coast.
