I was a post-doctoral Research Associate at the Centre for Medical Image Computing, working on software development for surgical guidance in minimally invasive surgery. I previously obtained a PhD from the Department of Computing at Imperial College London, focussing around appearance modelling for minimally invasive surgery.
This project develops a guidance system for actual use in surgery. I am developing software for image processing, live video streaming, visualisation, high-performance computing, and general architecture.

This
project focussed on liver modelling for tumour resection. It
investigated on growth modelling, resection simulation, virtual
training and biomedical simulation. I was working on texture map
generation/synthesis for virtual organ models.

I
was working on video mosaicking to expand the narrow field of view of
endoscopic cameras.
