To understand and model corneal transparency at the cellular and fibrillar level taking advantage of new developments in three dimensional ultrastuctural imaging by Serial Block Face Field Emission Scanning Electron Microscopy
The development of biological artificial corneal replacements.
Understanding the structural basis for loss of transparency or refractive function in the pathological cornea.
Three dimensional structure of the proteoglycans in the cornea and how it controls corneal transparency.
I currently manage the Structural Biophysics groups Zeiss Sigma VP Field Emission Scanning Electron Microscope with 3view 2 (Gatan) and Jeol 1010 100Kv Transmission Electron Microscope. As an experienced electron microscopist I also provide training in electron microscopy, EM sample preparation and ultramicrotomy to students within the Biophysics group.
