I have recently moved to Cambridge, UK, and started on a new job at Xaar that's taking all my time and then some.

You can also check some of my code at github.
My full résumé.
I've spent the last 19 years at HP doing research and development, with a 3 year detour as a manager. I've done most of my work on the digital processing of images in preparation for printing. My most significant contributions are an algorithm for spreading ink-jet drops in passes (for which I got several patents) and starting and leading the development of a piece of software that is now at the core of most of our high-end printers, and is being used by six HP printer divisions all over the world.
During these years I have also written several on-line apps, mostly in Perl and Python, and lots of programs for data analysis.
I enjoy mechanical models: my PhD thesis was about using the Lagrange equations to model the behavior of a collision of a 3-D body with finite tangential stiffness at the collision point, and for my last project I have written a Common Lisp program that computes the position of up to 80k stars and all the planets to generate a beautiful star chart in PDF format.
I am at my best when working with a
bash terminal and
emacs, either in Linux or in OS-X.
