Current Research Interests:

            Research in the Krusemark laboratory is focused on the discovery of functional small molecules using the power of in vitro evolution.  DNA-programmed combinatorial chemistry (DPCC) enables the "translation" of DNA constructs into DNA conjugates with wholly synthetic small molecules, thus enabling Darwinian-like selections. DPCC allows the synthesis and functional interrogation of small molecule libraries of unprecedented size and complexity (presently up to 1010 members).  

            The Krusemark lab works on the further development of the DPCC technology, towards the goal of a streamlined system for generating drug leads and biological tool compounds.  We use a combination of chemical, engineering, and molecular biology methods. We are working to expand the synthetic toolbox available for building molecules on unprotected DNA towards drug-like small molecules.   Our lab will develop tools to study the protein kinase C (PKC) family of kinases, which are involved in the signal transduction pathways of numerous and varied cellular processes.
