Research Focus

Membrane proteins account for about one third of human genes and comprise more than 50% of human drug targets. Our laboratory is currently focusing on the development of innovative methodologies and chemical tools enabling the structural and functional characterization of membrane proteins. We engage in a number of collaborative projects with experts in membrane protein structural biology to solve biologically significant structures. A second major interest of our laboratory is to study the interactions between membrane proteins and lipids that govern the protein stability and function. We are also interested in the development and discovery of small molecule therapeutics targeting a class of transporters to overcome multidrug resistance in cancer and infectious disease. Developing synthetic methodologies to make biologically relevant molecules is another component of our laboratory.
