Danny’s research focuses on the atomic and molecular insights into the structure-function relationships of biomolecules. Danny coined the term, pyrophosphate cage, to describe how the potent antimicrobial peptide, Nisin, recognizes bacterial cell wall precursor, Lipid II, to achieve the novel targeted pore-forming bactericidal activity. He reported the first demonstration of direct structural investigation of the dynamic co-translational folding events of a nascent polypeptide chain as it emerges from the ribosome by using NMR, which has paved the way towards fundamental understanding of protein folding and misfolding. He also unravelled unique structural and dynamic features of several oncogenic DNA/RNA G-quadruplex forming motifs to help drug designs. After starting his independent career in Taiwan, Danny continues to deepen our basic understanding of protein folding while collaborating with several research teams to study novel lectins and glyco/membrane proteins, and designs of better lectin inhibitors. His recent research focuses on how mutations impact on host recognition and immunity escape of coronaviruses, and how cancer-associated mutations allosterically impair the deubiquitinase activity and increase aggregation propensity of an important oncogene suppressor BAP1. Danny also establishes industrial collaborations to characterize the physicochemical and structural attributes protein drug targets.
