Chemical Biology, Bioinorganic Chemistry, and Inorganic Chemistry

Our laboratory studies the chemistry of biology and energy. We advance new concepts in imaging, proteomics, drug discovery, and catalysis by drawing from core disciplines of inorganic, organic, and biological chemistry. For example, we have developed activity-based sensing as a general platform to identify transition metals, reactive oxygen species, and one-carbon units as new classes of single-atom signals for allosteric regulation of protein function. These chemical tools also reveal unique metal and redox disease vulnerabilities as targets for innovative drug discovery efforts to treat neurodegeneration, cancer, and metabolic disorders. Our work in artificial photosynthesis addresses global challenges in climate change. We use design concepts from biology to develop molecular electrocatalysts for carbon dioxide capture and conversion and nitrogen/phosphorus cycling. Representative project areas are summarized below.

Transition Metal Signaling and Metalloallostery: Bioinorganic Chemistry Beyond Active Sites. We are advancing a new paradigm of transition metal signaling, where metal nutrients like copper and iron can serve as dynamic signals to regulate protein function by metalloallostery, going beyond their traditional roles as static active site cofactors. We develop activity-based sensing probes for imaging mobile transition metal pools and activity-based proteomics probes for identifying allosteric metal sites in proteins. These chemical tools enable us to decipher the complex biology of sleep, cognition, and obesity in cell, zebrafish, and mouse models. We also develop medicines to target metals as disease vulnerabilities in cancer, neurodegeneration, and metabolic liver disorders. These drug discovery efforts focus on cuproplasia and cuproptosis, newly recognized forms of copper-dependent cell proliferation and cell death, respectively.

Activity-Based Sensing: Leveraging Selective Chemistry to Decipher New Redox and One-Carbon Biology. We have pioneered the field of activity-based sensing, where we develop chemical sensors for biological analytes that achieve high selectivity using reaction chemistry rather than conventional lock-and-key binding approaches. By applying these chemical tools to enable real-time imaging of reactive oxygen species and one-carbon metabolites at the single-cell, tissue, and animal level, we elucidate principles of how these molecular signals influence fundamental biological processes spanning epigenetics to immune response.

Activity-Based Proteomics: Bioconjugation Chemistry for Single-Atom Signaling and Redox Drug Discovery. We are establishing the area of single-atom signaling, focusing on the study of reversible interconversion of methionine and methionine sulfoxide sites in proteins by adding or removing a single oxygen atom. We develop activity-based proteomics probes to identify new targets of methionine modification as well as writers and erasers that regulate their single-atom biology. These chemical tools also reveal new ligandable hotspots for undruggable protein targets and pathways to accelerate the development of next-generation precision medicines that target redox disease vulnerabilities in cancer and neurodegeneration.

Artificial Photosynthesis: Catalyzing Sustainable Electrosynthesis. We develop catalysts for sustainable electrosynthesis to address climate change and rising global energy demands. Inspired by natural photosynthesis, which produces the value-added products needed to sustain life from light, water, and carbon dioxide, we use biological design principles to create synthetic molecular electrocatalysts for carbon dioxide capture and conversion as well as nitrogen/phosphorus cycling.
