My research group tackles the challenge of understanding how drugs work at the molecular level through a uniquely integrated approach that combines chemical reporter technologies with state-of-the-art chemoproteomics. Chemical reporters—based on fluorescence, optical, and chemiluminescence platforms—allow us to monitor enzyme activity states, quantify target protein abundance, and visualize biochemical changes in living systems with high temporal and spatial resolution. These functional readouts reveal when and how molecular events unfold in response to small-molecule intervention. Chemoproteomics complements this by delivering a proteome-wide map of direct and indirect drug–protein interactions in their native context, enabling precise identification of both on- and off-target effects. Together, these complementary strategies create an exceptionally powerful framework for elucidating drug mechanisms, validating therapeutic targets, and uncovering new biology that drives the discovery of next-generation therapeutics.
