The eye is a complex organ that contains central nervous system tissue, but also remarkably accessible to view and study. It can be used as a window into the human body and a means of detecting ocular diseases, in addition to diabetes, heart disease, cancer and multiple sclerosis. My experience and understanding of biophysics, engineering and physiology provide me with the opportunity to approach vision and eye research problems from a unique perspective. Two important priorities for my research projects are:

  1. Research that is a balance of experimental methods and clinical relevance
  2. Multi-disciplinary collaborations and approaches to assist in answering important questions

The research area in which I am most enthusiastic is non-invasive imaging for disease detection and prevention. I have utilized a variety of imaging techniques in my previous and current work including microscopy (light, fluorescence, intravital video), micro-computed tomography, scanning laser ophthalmoscopy and optical coherence tomography. My current research is investigating the variability of optical coherence tomography angiography and developing reliable quantitative measures from the acquired data. Developing new tools and methods for non-invasive imaging of the eye is required for accurate longitudinal results and to obtain a better understanding of disease progression.
