Professor Mike Edwardson University positionHead of Department Professor Mike Edwardson is pleased to consider applications from prospective PhD students. DepartmentsHome pagehttp://www.phar.cam.ac.uk/researc... (personal home page) Research ThemeInterestsMy research involves imaging of biomolecules using atomic force microscopy (AFM). AFM permits the visualization of single molecules under near-physiological conditions. Current projects include studies of: 1. The subunit arrangement in ionotropic receptors. 2. The structural changes occurring during receptor activation. 3. The association of sigma-1 receptors with ion channels. 4. The behaviour of proteins involved in membrane fusion during neurotransmitter release.  The AFM image shows neurotransmitter-containing vesicles docked at the plasma membrane of a PC12 cell.
