My research interests are mainly focused on chromatic aberration. In this field, I am working on dispersive eye models that include GRIN lenses, building a physical model eye that is capable of simulating certain amounts of chromatic aberration and finally, investigating the effect of dispersion on an adaptive optics system. Some of my research on chromatic aberration was carried out as a visiting junior fellow at Tokyo Institute of Technology, Japan. I have also spent time researching and developing new contact lens testing methods.
