Introduction
My interdisciplinary research programme has two main themes; computational neuroscience for vision and audition, and signal processing for audio, visual, and neuroscientific applications. These two research themes are connected by the idea that efficient representations of signals, such as those presumably employed in the brain and those desirable for engineering applications, should be matched to the statistics of the input signals. My work explores the consequences of this idea for perception and neurobiology. Moreover, it uses this general scheme to develop superior signal processing representations that outperform traditional non-adaptive approaches. Practically, machine learning methods are a key component of my work as they are used to automatically adapt representations to the statistics of the input.

Here's my cv.

Current Highlights:

• Appointed University Lecturer in Computer Vision and Machine Learning in the University of Cambridge Engineering Department (starting September 2012)
• A short talk providing an overview of my research programme.
• New Conference Paper: Probabilistic amplitude and frequency demodulation. Awarded spotlight presentation at NIPS 2011. Supplementary material.
• New Journal Paper: Demodulation as Probabilistic Inference. There is an associated webpage with code and a listing of related publications here.
• A finished version of my PhD Thesis, Statistical Models for Natural Sounds is now ready. There are also a number of related audio demonstrations.
• Awarded an EPSRC Postdoctoral Fellowship Grant at the Interface for the Life Sciences. This is a prestigious three year grant that I will spend at the CBL Lab in Cambridge with Zoubin Ghahramani and at the Lab for Computer Vision, NYU with Eero Simoncelli.

Workshops and meetings organised

• Essential Tools for scientists meeting. A weekly meeting to discuss topics essential to scientific life, which are not formally taught. Things like unit testing, acceleration of code, reference management, version control, time-management, latex, presentation style, etc.
• Advanced probabilistic techniques workshop A two hour lecture on a probabilistic method (loopy BP, EP, DBNs, DPs and SMCMS) followed by coding up the method on a toy problem in a pair
• Beyond Simple Cells (BSC) workshop Computational modelers of visual cortex meet the physiologists whose data they try and model.
