Research interests

My main research interests are focused on the development and application of optical imaging techniques, specifically optical coherence tomography (OCT), to study biomedical systems for preclinical or clinical research. In particular, I am interested in the role of microvascular hemodynamics in the progression of various brain and eye diseases.

Techniques, methods & infrastructure

I primarily use Optical Coherence Tomography (OCT) for brain and eye imaging in small animal (mouse and rat) models.  In addition to traditional OCT methods, I have also developed new methods based on spectral and exogenous contrast.
