Research Groups

  • VSBL: Vivat Scientia Bioimaging Labs
  • MRG: Macula Reseach Group

Research Summary

I am currently employed in a dual role at School of Optometry and Vision Sciences; to support and develop the work involving the OCT (optical coherence tomography) research instruments within the school as part of the VSBL group and to advance the field of imaging densitometry as part of the Macula Reseach Group. I also provide training for the custom built, long wavelength OCT system so that other users can operate the system independently. I have also helped users to acquire and analyse OCT data for a variety of different projects including electrophysiology, ex-vivo optic nerve head and pathological retinal imaging. I also provide custom distributed image processing software, expertise on optical and mechanical design and Labview and Matlab programming.

Current Reseach Projects

I am currently involved in a 3 year project using a technique called imaging densitometry with the aim of detecting the early signs of MD (macula degeneration). By using a range of different colour light soruces, we record the signal reflected from the retina under photopic (light adapted) and scoptopic conditions (dark adapted). By analysing the ratio of the two signals and their time dependency, we can ascertain how well the retina is performing.

Past Research Projects

My PhD was entitled Full Field Swept Source Optical Coherence Tomography. The aim of this research was to develop a novel approach to OCT and build a prototype system to investigate its potential. I was able to successfully build the prototype and acquire 3D ex vivo images of retinal samples with image quality comparable to clinical systems. The work involved mechanical construction of the prototype, optical design, interfacing the electronic controls, writing the control code and analysing the completed system
