We use organic synthesis to build molecules for practical purposes. Research projects involve: 

  1. The synthesis of nucleotides and proteins with vibrational reporters such as azides, nitriles, and selenocyanates to monitor electrostatic environments and solvent dynamics by IR spectroscopy.
  2. The design and synthesis of air-stable, water-soluble organic radicals such as polarizing agents for dynamic nuclear polarization (DNP). 
  3. The history of organic chemistry.
  4. Molecular knots.  
  5. Collaborative work to synthesize ganglioside GM3 to help Amish children.
