Biography

 

James Hopgood is a Senior Lecturer in the Institute for Digital Communications, within the School of Engineering, at the University of Edinburgh, Scotland. He works in the disciplines of Data Science and Machine Learning within the field of Statistical Signal Processing, a branch of Electronic Engineering. 

James's research specialisation include model-based Bayesian signal processing, speech and audio signal processing in adverse acoustic environments, including blind dereverberation and multi-target acoustic source localisation and tracking, single channel signal separation, distant speech recognition, audio-visual fusion, medical imaging, blind image deconvolution, and general statistical signal and image processing.

James received the M.A., M.Eng. degree in Electrical and Information Sciences in 1997 and a Ph.D. in July 2001 in Statistical Signal Processing, part of Information Engineering, both from the University of Cambridge, England. He was then a Post-Doctoral Research Associate for the year after his Ph.D within the same group, at which point he became a Research Fellow at Queens’ College continuing his research in the Signal Processing Laboratory in Cambridge. James joined the University of Edinburgh in April 2004.

Since September 2011, he is Editor-in-Chief for the IET Journal of Signal Processing. James is the Programme Director for the MSc in Signal Processing and Communications at the University of Edinburgh. 

Research Interests

James’s interest in audio-signal processing in adverse acoustic environments covers a variety of research topics including: acoustic source localisation and tracking; blind enhancement of de-reverberation of speech and music; environmental noise reduction for acoustic sensing from remote mobile platforms; acoustic weapons fire and gunshot localisation; intelligent sensing form mobile robots; and ad-hoc acoustic sensor networks.

You can listen to some of James's recent work in his short public lecture talk from Edinurgh's Innovative Learning Week entitled "Separation and Marriage: Signal Processing for Life Science".

Positions available

PhD Position Available: Microphone array based acoustic event analysis, Distributed Source Localisation. Please contact me for further information.

Teaching

Teaches two undergraduate courses, Signals and Communications 2 and Signals and Communications 3, in the second and third year respectively.

Also teaches two full Masters course on "Probability, Random Variables, and Estimation Theory", and "Statistical Signal Processing". Extremely comprehensive courses notes are available for all four courses, along with a series of lecture recordings, tutorial questions, and solutions.

I also teach on the UDRC Summer School at Master's level. For more information, watch this video!
