Summary

 

Summary

Andrew Walden's primary research interest is best described as statistical signal processing, covering time series, spectral analysis and wavelets. #

He is particularly interested in making these areas as accessible as possible through careful attention to practical implementation issues. His books, co-authored with Don Percival, on Spectral Analysis and on Wavelets attempt to achieve this goal. #

He is particularly interested in statistical signal processing for the physical sciences and medicine, and spent nine years as a researcher with BP before coming to Imperial College.
