Research interest on biopharmaceutics is to utilize human endogenous proteins as carriers for drug formulation, targeting and delivery.
Dr. Li's research interest on biopharmaceutics is to utilize human endogenous proteins as carriers for drug formulation, targeting and delivery. He has developed a human serum albumin-based platform to create recombinant albumins that can recognize designated protein targets and utilize their native biochemical and biological functions to deliver small molecule, peptide and nucleic acid drugs. These recombinant target binding albumins can be applied as antibody alternatives in clinical therapy and bioscience research.
Another direction of Dr. Li's research is on structure/function study of DNA type IA topoisomerases and RecQ-like helicases. These enzymes play critical roles in DNA recombination and repair. Methods in biochemistry, biophysics, genetics and molecular modeling are employed to elucidate the biological functions of these enzymes. Meanwhile, he is also interested in screening and designing new antibiotic and anticancer drugs that target type IA topoisomerases and RecQ helicases.
