The research of our group is focussed on the role of metals, in particular iron, in plants and microbes. 

We aim to understand how iron cofactors are assembled in different cell compartments, using model plant species and yeasts. Ultimately, the iron that plants take up from the soil and use for their own needs is an important source of human iron nutrition.

Iron is a versatile catalyst associated with proteins in the form of iron-sulfur clusters, haem or other forms. Iron-sulfur proteins are abundant in plants, playing key roles in photosynthesis, respiration and nitrogen fixation. We have so far catalogued more than 100 confirmed and putative Fe-S proteins encoded in the Arabidopsis genome, underpinning virtually every aspect of photo-autotrophic growth. 

Our research in the past few years has led to the identification of new proteins required for iron-sulfur cluster assembly and established the interrelationship between cofactor assembly pathways in the cell.
