I am a postdoc at David MacKay's Inference Group at the
University of Cambridge (2009-2012). I was a PhD student at the Digital Signal Processing Group at the
University of Stellenbosch, South Africa (2002-2005). My undergraduate
degree was in Electronic Engineering (1998-2001). After receiving my PhD, I
moved to Oxford, where I worked at
Oxford Metrics Group as a researcher and algorithms engineer in the Vicon Research Unit (2006-2009).
My research interests include the application of machine learning
algorithms to computer vision problems. My PhD was about the extraction of
dynamic information from static signatures (e.g., signatures on cheques)
with specific application to signature verification. More information on
this project can be found
[here]. During my time at Vicon I helped to develop high-level computer
vision algorithms and low-level image processing algorithms to extract 3D
information from multiple video cameras (without the use of optical
markers). My current research focusses on the problem of gaze tracking and
the detection of facial gestures to communicate through programs such as Dasher and Nomon. I am specifically
working on the
Opengazer project, which aims to assist many impaired users, e.g.,
patients with locked-in syndrome, to communicate.
