Research Program
Scientists in the "Biomolecular Systems" department use synthetic chemistry as an enabling technology to investigate complex biological systems with a particular focus on glycobiology. Carbohydrates play crucial roles for structure, energy storage and molecular recognition events that are essential to living organisms but are also important to infections, the immune response and cancer development. Complex sugars that coat most cells are the basis for vaccines against bacteria, parasites and viruses.
Automated glycan assembly quickly and reliably produces biologically relevant carbohydrates as large as 151-mers that serve as important probes for biological and medical research as well as for material science investigations. Many of the fundamental advances made in this department have translated into products and services by spin-off companies.
The core interests of our research are currently focused on the following areas:
