My research focus will be at the interface of Chemistry and Chemical Biology. Chemical tools such as affinity and activity-based protein profiling will be developed to harness biological targets. Different cell imaging techniques will be integrated for better mechanistic understanding of neurodegenerative diseases.


Current Research Interest

  • Design and development of novel ligands for the metal-catalyzed enantioselective synthesis of medicinal scaffolds.
  • Identification of highly selective kinase inhibitors via late-stage C-H activation/ functionalization of heterocycles.
  • Photo-affinity and activity based protein profiling for the identification of biological target of small molecules.
  • Development of radiopharmaceuticals for PET imaging for the early detection of breast cancer and neurodegenerative diseases.
  • Exploring biocompatiblechemical reactivity for posttranslational modifications (PTMs) of proteins.
