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.
