Dr Buchanan is Chief of the Section on Structural Biology of Membrane Proteins in the National Institute for Diabetes & Digestive & Kidney Diseases, at the National Institutes of Health. She received her Ph.D. from the Johann-Wolfgang-Goethe Universität in Frankfurt, Germany in 1990. She completed postdoctoral fellowships at the MRC Laboratory of Molecular Biology, Cambridge, UK, and at UT Southwestern Medical Center, Dallas, before returning to the UK to establish a research group at Birkbeck College, London in 1998. She joined the NIDDK as a tenure track investigator in 2001 and is currently a senior investigator in the Laboratory of Molecular Biology, NIDDK. Research in Dr Buchanan’s laboratory focuses on the structure determination of integral membrane proteins by X-ray crystallography and functional analysis of these proteins using biophysical, biochemical, and cell biological techniques. Current topics include small molecule and protein import across the bacterial outer membrane, protein secretion by pathogenic bacteria, and protein import across mitochondrial outer membranes.
