Plants are the basis of food security and energy / CO₂ capture on planet Earth. The major challenges of climate change and population growth mean that we need to grow 60% more food by 2050 in a period where both cold and warm temperature shocks and extreme weather events are occurring with increased frequency. Therefore, novel insights into harnessing plant growth based on fundamental discoveries are required. One area of unexplored potential is how the individual functional components within the cell (known as organelles) are organised and controlled.

Organelles within plants show rapid and coordinated movement which is critical for normal growth and development as well as enabling the plant to respond to environmental conditions. Organelles are known to change shape and alter their movement during certain stresses, including heat and cold stress. However, we do not know precisely how this movement occurs although we know it is driven by the actin cytoskeleton and special motor proteins.

The actin cytoskeleton is an intricate filamentous network in the cortex of plant cells which, if disrupted, stops organelle movement. My research utilises using specialised microscopy to study how the actin cytoskeleton interacts with organelles, driving movement within the cell.
