Altered redox biology is characteristic of several pathological states, including cancer. Redox therapeutics are thought to act by altering the intracellular concentrations of oxidants within cancer cells such that the levels can no longer be tolerated and the cells die. Currently, quantitative measurements of effective perturbations to achieve certain phenotypes (e.g. apoptosis) are lacking. My research focuses on understanding and quantifying what happens when the intracellular levels of hydrogen peroxide are altered, particularly when this perturbation is localized to certain organelles. This data will ideally contribute to the design of new treatments to combat cancer.
