Research Interests

Resistance to standard antibiotic therapies is a growing health concern around the globe. Certain infections that are essentially untreatable have been identified in both hospital and community settings. The increasing frequency of drug resistance has been attributed to a combination of antibiotic over-prescription and societal and technologic changes that affect the transmission of drug-resistant organisms.

The ultimate goal of the research in our laboratory is the structure-based design of novel, therapeutically useful antibiotics and inhibitors of antibiotic-resistance mechanisms. To achieve this goal we use a combination of x-ray crystallography, molecular modelling, molecular docking and molecular biology in collaboration with medicinal chemistry to engineer drugs that specifically interact with and disable critical bacterial target proteins.
