James Nelson joined the Department of Statistical Science as a Lecturer in 2010 and became Senior Lecturer in 2013. After a
PhD in applied harmonic analysis from the Mathematics Department at Anglia
Polytechnic University (1998-2001), he held post-doc positions in: the Applied
Mathematics and Computing Group at the University of Cranfield (2001-2004); the
Information: Signals, Images, and Systems Research Group at the University of
Southampton (2004-2006); and the Signal Processing and Communications Laboratory at
the University of Cambridge (2006-2010).
Multiresolution analysis; random fields; spatial models; statistical machine learning; statistical signal and image processing. Examples: Markov random fields; wavelet/Riesz basis and packet construction and pursuit/optimisation; sparsity and other regularisation with applications to detection and classification; weak self-similar random fields; support vector machine kernel construction and hyper-parameter estimation; generalised cardinal series and sampling theory; robust, regularised Hurst parameter estimation for texture and volatility models.
