Philipp K. Janert

My education is in Physics, and I have worked as technology consultant, software engineer, technical lead, and project manager, for small start-ups and in large corporate environments, both in the US and overseas. I provide consulting services specializing in corporate metrics, business intelligence, data analysis, and mathematical modeling through my company, (Principal Value, LLC). I also teach classes on software design and data analysis at the University of Washington. Since starting this book, I have contributed a few patches to the gnuplot development version. I was thus able to add some features to gnuplot that I had been wanting desperately for years, providing further proof for the power of the open-source model. I hold a Ph.D. in theoretical physics from the University of Washington.
