Research Summary

I am currently interested in the role of mitochondria in ischaemia/reperfusion (I/R) injury, occurring in heart attack, stroke and organ transplantation. In particular, I am interested in the role of the mitochondrial metabolite succinate and the role it plays in the production of reactive oxygen species (ROS) in the damaging events and signalling. By perturbing succinate metabolism, I hope to develop new therapeutic strategies to ameliorate I/R injury.

Absolute quantification of succinate (and other mitochondrial metabolites) from tissues and cells is carried out using a Shimadzu LC-8060.
