Research Overview

My research centres around the application of electron optical techniques, especially transmission and scanning electron microscopy, to investigate the ultrastructure of connective tissues. The overarching hypothesis for my work has been that composition and structure of tissue matrices define tissue function. In the past I have worked in the field of musculo-skeletal biology, investigating the fine structure of ligaments and cartilage, to try to understand the changes within these tissues in degradative diseases such as osteo- and rheumatoid arthritis. For the past ten years I have worked in collaboration with Professor Andrew Quantock focussing on ocular tissues, including cornea, sclera and trabecular meshwork. A range of tissues obtained from human eyes, through both local and international collaborations, have been investigated to characterise the nature of interactions between collagens and proteoglycans in health and disease.

Our studies have involved a number of cutting edge technologies for microscopy, both in relation to new preparation techniques for tissue preparation, for example using low temperature tissue preservation (high pressure freezing and freeze substitution), and novel instrumentation for image acquisition (serial block face 3View® SEM). Throughout my career I have maintained a keen interest in new methodology for electron microscopy. I have applied specialised localisation methods employing specific antibody markers to identify minute differences in tissue components, proteoglycans, during development of the cornea in the embryo. These appear to be important for the maturation of a transparent matrix, itself essential for vision. The same tissue molecules are also involved in the pathogenesis of certain blinding conditions where enzyme deficiencies gives rise to opacities in the cornea, eventually requiring a corneal transplant for treatment.

Currently there is enormous interest in 3D imaging techniques, not only in diagnostic imaging such as with OCT, but also at the level of single cells and matrix macromolecules. These methods of electron tomography and, most recently, serial block face scanning electron microscopy are being used in our electron microscopy laboratory in the Structural Biophysics Research Group.


Teaching Overview

I currently assist with laboratory-based teaching of postgraduate research students and undergraduates carrying out final year research projects.
