Jodian Thomas, MPhil Student
Bachelors of Science in Medical Physics, with honours
Minor in Environmental Physics
Postgraduate Research in Application of Medical Physics to Optical Diagnostics of Prostate Cancer in Jamaica.
Title: Early Detection of Precancerous Tissue of the Prostate using an Optical approach.
Abstract:  The cancer of the prostate usually begins in the epithelial cells of the peripheral zone of the prostate gland.  Changes in cellular mechanism and morphology are the earliest states of the malignant transformation.  By using an optical technique such as Fluorescence Spectroscopy, Reflectance Spectroscopy , Polarization Spectroscopy and even Quantization of Zinc or Citrate Content, we can determine if a cell and possibly a tissue is developing malignancy.  Measuring and analysing the statistical differences for optical parameters such as refractive index and zinc concentration for normal, precancerous and carcinoma tissue and doing so with a high Specificity and Sensitivity are some of my main objectives.
