My research focuses on developing new protein biosensors for reactive oxygen species that are present within biological systems. These sensors have the potential to provide quantitative information about the levels of key species in mammalian cells (e.g. hydrogen peroxide and superoxide) with high spatial and temporal resolution, and to elucidate the role that these species play in various signaling pathways and disease states in mammalian cells.
