About Me

I'm a fourth year PhD student at the Visual Geometry Group, University of Oxford. My supervisor is Prof. Andrew Zisserman. I work mainly on efficient large-scale particular object retrieval but have also dabbled in machine learning and probabilistic models for vision.

In 2009, I co-founded a company, Plink Search, aiming to develop visual search engines for mobile phones. Our first application, Plink Art, which allows users to search for information on artworks by visual example, won the Education/Reference category of the Android Developer Challenge.

In 2010, Plink Search was acquired by Google! You can read more about it here.
