I am a Lecturer in Computer Science with the Risk and Information Management (RIM) group at QMUL. Previously, I coordinated the behaviour monitoring work package for the SAMURAI EU FP7 project at QMUL ('08-11). During my PhD, I worked with Sethu Vijayakumar in the Statistical Machine Learning and Motor Control group and Edinburgh's IPAB and ANC institutes.

My background spans informatics & neuroscience (PhD Neuroinformatics, Edinburgh, 2008; MSc Neuroinformatics, Edinburgh 2004), machine learning (MSc Informatics, Edinburgh, 2003) and computer science (BA Computer Science, University of Cambridge, 2002).

My academic interests include probabilistic modelling and machine learning: applied variously to interactive learning, structure learning, data mining, computer vision, behaviour understanding, data fusion, robotics, motion-capture, novel human-computer interfaces and theoretical neuroscience.
