Research Overview

• 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.

• Corneal development.

• Three dimensional structure of the proteoglycans in the cornea and how it controls corneal transparency.


Other Duties

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.
