Understanding the mechanism of action of receptor-like antibacterial agents (vancomycin and bacitracin) and improving upon their function.
Utilize combinatorial chemistry to accelerate the discovery of antibacterial agents with increase potency towards resistant organisms .
Synthesize derivatives of the drug vancomycin and develop a novel way to counteract drug resistance.
Synthesize the antibacterial agent bacitracin and its analogs in a biomimetic fashion using solid phase peptide synthesis
