The Azimuth Project

At the Azimuth project I am writing blog articles, starting with a series on Petri net programming. My plan is to study math and science and then teach it to colleagues in software development. We need more scientists to solve the myriad of problems that beset the human race, and the world of programmers provides a large recruitment base for the sciences.

I am also a key member of the Azimuth Data Backup Project.

I am a statistician and engineer working for Akamai Technologies. I live with my wife, Claire, in Westwood, MA.

I’m an active student of climate science and Bayesian methods. You can learn more about me here, and from my LinkedIn profile. I am a member of the American Association for the Advancement of Science, the Ecological Society of America, the American Meteorological Society, the American Statistical Association, the International Society for Bayesian Analysis, the Institute of Electrical and Electronics Engineers, the Citizen Science Association, and both the 1930 Society and the Fye Society of Woods Hold Oceanographic Institution.

I am also somewhat active in social and political activities relating to the environment, mostly through the Green Congregation Committee at the Unitarian Universalist congregation to which I belong, First Parish in Needham, MA.

At the Azimuth project I am writing blog articles and hope to collaborate on quantitative and statistical problems pertaining to climate and combating environmental degradation.

I am also involved in other citizen science efforts principally because I work best with planning gathers of field data and analyzing it, and Azimuth tends towards more theoretical and analytical research.

Warming slowdown? (part 1 of 2)” The idea of a global warming slowdown or hiatus is critically examined, emphasizing the literature, the datasets, and means and methods for telling such. Also available at the Azimuth Project wiki.

Bayesian inversion of commingled tonnage of municipal solid waste to isolate components” Bayesian inversion to recover latent components in mixtures is a standard technique, with wide application. Yet, apparently, it is not well known. Frequentist methods for doing this are known as algorithms for blind source separation.

Areas of Interest

  • Bayesian statistics, especially computational challenges, tutorials
  • Time series and state-space methods. Non-parametric approaches for time-varying vector-valued responses with time-varying and often censored predictors.
  • Climate science, especially implications for oceanography. Engineering of clear-air capture of carbon dioxide.
  • Statistical and mathematical methods for field and observational sciences, especially ecology and biology.
  • Statistical support to citizen science efforts, after Kosmala, Wiggins, Swanson, and Simmons.
  • Combining analysis of natural language and machine-derived stylized text with statistical methods
  • Mastering compelling graphics and illustrations using the facilities in LaTeX PGF/Tikz


  • Inferring latent causes and relationships regarding the drinking water supply in the town of Sharon, MA and, more generally,
  • Developing techniques which facilitate interpretation of data gathered by volunteers in the field and natural settings censored by seasonal availability
  • Expanding participation in citizen science as a means of getting more people involved with and understanding the nature and process of scientific activity
