John is a plant biologist who uses microscopy to study living cells. This type of research helps to answer questions about the ways in which cells and organisms grow and develop. The focus of research in John's group is on how different structures within cells interact with each other.

John's research looks specifically at the surface of living plant cells using fluorescence microscopy. By studying protein interactions, John's group learn how plants perceive and interact with their environments.
