HUNSEN GROUP RESEARCH INTERESTS

Carbohydrates are one of the most abundant organic compounds in nature.  In addition they possess a tremendous amount of structural diversity.  The research endeavor being undertaken in Hunsen’s Lab focuses on tapping the abundance and rich structure of carbohydrates and other natural products. 

The projects currently under investigation in this lab are:

  1. Design, synthesis, biological activity studies of natural product based drugs for cancer prevention and treatment.
  2. Pharmacoproteomics study of  the mechanism of action of natural products on cancer cells.
  3. Carbohydrate Chemistry
  4. Green Chemistry: Green oxidation reactions and Enzyme catalyzed polymerization reactions
