Dr Alexander (Sandy) MacRobert

Sandy MacRobert

Reader (in Photochemistry and Photobiology), National Medical Laser Centre.

Graduated from University of Cambridge, PhD from University of London, Queen Mary College.

Dr MacRobert has carried out research at University of Oxford, University of Bielefeld, Germany, The Royal Institution and Imperial College London.

 

Current Research Interests

Development of new photosensitisers, 5-aminolaevulinic acid derivatives and delivery systems for photodynamic therapy. Studies of the photophysical and photochemical properties of photosensitisers, including fluorescence/phosphorescence lifetime imaging.

Biomedical applications of optical spectroscopy, including optical diagnostics of tissue constructs and fluorescence imaging for early cancer detection.
