Scientific Data Processing Tutorial and Book

When I retired from the University in 1999, I noticed that I was getting a lot of page-views on one of the course websites that I had taught, even though I was no longer teaching that course. Most of the interest was directed to a lab experiment in digital data processing. I was getting an increasing number of emails with questions, suggestions, and comments from people in widely varied scientific fields from all over the world. This encouraged me to broaden this material beyond chemistry and my specific course and to make this a long-term retirement project. My aim is to help science workers learn and apply computer-based mathematical data processing techniques, by producing free tutorial materials that explains things intuitively rather than in mathematical formality, with coding examples, practical software, and guidance/consulting on specific projects.



This has developed into a very popular Web-based tutorial and a handbook of signal processing. The book is available in paperback format from Amazon and in a free PDF version. Described as 'the best document on signal processing' and 'a goldmine' of practical, clear, and comprehensive explanations, this handbook has been praised for its unparalleled clarity and extensive resources. Users highlight its invaluable contribution to both education and research, often calling it a 'phenomenal' and 'indispensable' tool that has significantly enhanced their understanding and work in the field. Click for verbatim reader reviews.

To support this, I also developed a free toolkit of software programs for signal processing for science researchers and students that has been lavishly praised.

My data processing website has now been viewed over two million times from 206 countries and has been cited in over 750 published papers, theses, and patents.The development of the project is described on "How this site came to be".


Ornamental Shade Gardening

When my wife and I retired in 1999, we thought that it would be a good active retirement hobby to landscape our back woods into an ornamental woodland garden. This is the story of that 25-year project.

Educational technology workshops for teachers

In the early 2000s and 2010s, my wife and I developed and presented a series of workshops for teachers on the applications of educational technology, which we presented a a number of middle schools in Montgomery County, Maryland. We also taught  several Adult Education Courses on technology-related topics, including digital photography, digital sound, and basic PC maintenance. The latter were sponsored by the Collier County Public Schools and taught in Naples, FL, where we have spent the winter since retirement in 1999.
