Professional Interests
My research interests are concerned with fundamental structural biochemistry problems that have direct links to the understanding and treatment of disease, primarily of the extra cellular matrix of mammals. The principal techniques for study being: X-ray fiber diffraction and crystallography.
The lab also deals with protein folding, aggregation of biological polymers and membrane surface active helices (see the HHELIX server).
