Pleased to share my new review:

Ovulation: A cellular symphony in three movements 💥🥚

Ovulation is more than egg release—it's a tightly regulated, tissue-scale process. Here, I present a temporal framework structured as a symphony performed by the cells of the follicle.

We've just been awarded a grant to study the cellular basis of regeneration – to track the progenitors of sensory organs in the context of leg regeneration, in our favourite crustacean tinyurl.com/parhyale, based on live imaging and cell tracking. The project involves some cool collaborations... 1/3

In our new @annualreviews.bsky.social piece, we explore how bioelectricity is generated, sensed & translated into responses that sculpt tissues, guide growth & enable tissue regeneration.

Bioelectricity in Morphogenesis

Bioelectricity is likely as old as life itself. From the moment the first proto-cell was enclosed in a lipid bilayer, a membrane potential arose. Thus, one can expect that bioelectrical activities inf...
