Laboratory of Pharmaceutical Chemistry

The research focus of our laboratory is bioactive peptides, functional polymers, and their potential pharmaceutical and biomedical applications.

Bioactive peptides

Research topics in this project includes:

  • design peptides with desired biological functions
  • develop novel peptide delivery method using peptide self-assembly technology
  • We have successfully developed several peptides with anti-heparin, anti-cancer, or antibacterial activity
Functional polymers

We are interested in smart polymers. Current research topics include:

  • develop functional polymers grafted surfaces with good biocompatibility
  • synthesize drug selectively bound polymers for drug formulation and delivery

Open Positions:

Graduate student positions are available in our lab. Motivated students who are interested in our above research projects are encouraged to apply. Special consideration will be given to students with majors in Biochemistry, Microbiology, and Organic Chemistry. Applications will be reviewed as they come in, and may also be reviewed after the target date (Sept 30, 2009) if the positions have not been filled.
