Dr. Carroll's research interests span the disciplines of chemistry and biology with an emphasis on studies of sulfur metabolism pertinent to disease states. Her lab focuses on the development of novel tools to study oxidative posttranslational modifications of cysteine thiols, profiling changes in protein oxidation associated with cancer, neurodegeneration, and diabetes, and exploiting this information for development of diagnostic and therapeutic approaches. In addition, her group investigates sulfur pathways that are essential for infection and long-term survival of pathogens such as Mycobacterium tuberculosis.
