Research amateur: trained: signal analysis & image processing (information enhancement, adaptive filtering, denoising, data compression, restoration, deconvolution, wavelets and filter banks, optimization), involved: basic statistics, visualization & data science, curious: language, words, epistemology, puns. Driven by applications, especially the extraction of weak signals in noise: geophysics/geosciences, analytical chemistry, engine control and simulation, materials analysis, and bioinformatics. ©
