Dr Julien Gronnier

Postdoctoral Scientist
Cyril Zipfel Group

In my PhD I studied the molecular mechanisms underlying plasma membrane nanodomain organization and function of Group 1 REMORIN during Plant-Virus interactions. I’m interested in deciphering how membrane-bound signalling events are orchestrates in space and time in order to ensure the development and survival of organisms.

I joined Prof. Zipfel group at the Sainsbury laboratory in May 2017. My work will focus on how the organization of cell surface signalling components mediates the conversion of extracellular inputs into optimal and specifics intracellular outputs.
