Research Focus

Our laboratory focuses on the identification of small molecule modulators of protein function as novel foundations for therapeutics and as tools for elucidating functional roles of enzymes in biological processes. The Wolan lab employs an arsenal of biophysical and cellular methods to identify new protein targets, improve and develop high throughput screening technology and validate potential lead molecules. Specifically, our efforts target candidate proteins for the identification of small molecule activators and the inhibition of bacterial enzymes involved in the proliferation of human disease.

Functional Proteomics of Human Microbiomes and Disease

Associations between human microbial environments and the onset of human diseases are rapidly materializing. Elucidation of the symbiotic relationships that have evolved between humans and microbes, and of the associated diseases, will provide a wealth of invaluable information that can be exploited in drug discovery. We employ functional proteomics towards the identification of bacterial proteins implicated in disease and the subsequent discovery and iterative design of small molecule regulators of enzyme activity. Our ultimate goal is the moderation of microbiome distribution, activity and host responses via external small molecule intervention as potential foundations for the prevention and treatment of diseases.
