Our Research

Using the genetic code expansion technique, a powerful tool to functionalize proteins, the genetically encoded amino acid inventory has been augmented far beyond the canonical 20 to include non-canonical amino acids that contain diverse chemical functional groups. This opens a door for an array of novel protein research.

Our major focus is to devise new genetic code expansion methods for the encoding of non-canonical amino acids in proteins in living cells and apply these methods in four major areas:

  1. Deciphering cancer epigenetics regulation of histone and P53
  2. Drug discovery using phase display
  3. Protein biosensor development for small molecular sensing and
  4. Development of new click chemical reporters for specific protein tagging and fluorescent cell imaging

Please visit our Publications page to see our latest work or visit Research to view the highlights of the research areas.

Bioorthogonal Reactions for Protein Modifications

Bioorthogonal reactions refer to chemical reactions that were performed in a biological system without interfering with the complex cell environment. We use these reactions to develop potential click chemistry.

Protein FRET labeling for biosensor development

Förster resonance energy transfer (FRET) between a pair of donor and acceptor dyes is an invaluable tool to study dynamic protein conformational changes such as conformation rearrangement and folding/unfolding.
