lab title

The focus of our research program is the structure determination of integral membrane proteins by X-ray crystallography and functional analysis of these proteins using biophysical, biochemical, and cell biological techniques. We study transporters embedded in the outer membranes of Gram-negative bacteria, which are surface accessible and therefore have the potential to be good vaccine and/or chemotherapeutic targets against infectious diseases. We also study the membrane associated or soluble protein partners that interact with outer membrane transporters to better understand how these systems function in vivo. Current topics in the lab include [1] small molecule and protein import across the bacterial outer membrane, [2] protein secretion by pathogenic bacteria, and [3] protein import across mitochondrial outer membranes.

header image for jobs

A postdoctoral position is available for structural and functional analysis of proteins involved in virulence and/or survival in pathogenic bacteria. We are particularly interested in developing drugs and vaccines that target multidrug resistant bacterial strains. See recent examples of our work in Nature 483:53-58 (2012) and Proc. Natl. Acad. Sci. USA 109:9857-9862 (2012). Candidates must have experience in protein structure determination by X-ray crystallography and will ideally have some experience in membrane or soluble protein expression, purification, and crystallization. Good biochemistry skills are essential. We are part of an interactive group of structural biologists sharing common home source X-ray facilities, dedicated access to beamlines at APS, and a common weekly group meeting.
