I started Systems View in 1997.  In 2013, I was asked to consult for NextHealth Technologies, a Denver start-up that was looking to use advanced analytics to help health insurance companies better engage with their members to reduce costs and improve health outcomes.  In 2014, I agreed to join NextHealth as an employee, and advanced to the position of SVP of Analytics before retiring in October 2019.   I had some great experiences at NextHealth, including the design and/or development of many of the algorithms at the core of their product.  I had the opportunity to learn a lot more about simulation-optimization, machine learning, bootstrap and Bayesian statistics, decision trees, and propensity score matching - not to mention learning about start-up company evolution, venture capital, stock options, boards, and all manner of corporate management processes.

During my time at NextHealth, I kept the lights on at Systems View with a few small legacy projects for some previous clients. Now that I have left full time external employment, I have the opportunity to apply my knowledge to some new endeavors.  ( I am starting with this first cut at a redesigned web site!)   Looking forward to this next phase.

I recently coauthored an interesting book

I was privileged to assist with the creation of an interesting book in collaboration with Dr. Tony Cox and Richard Sun.  I have worked with Tony, of Cox Associates, for over 20 years, and this book describes several key projects we have worked on.  These projects all involved health risk analysis, and the book describes in detail the methodologies we used.  The emphasis of these studies was on causal analytics, versus the many studies out there that mistake correlation for causation.  In fact, many of our efforts were motivated by a desire to (in)validate conventional wisdom in areas such as animal antibiotics and air pollution, where correlation has been misinterpreted.  However, the book is much more than a compilation of studies.  Tony does an excellent job of drawing higher level lessons and providing a how-to guide for risk analysts.  The book definitely has a point of view.  My favorite chapter title:  “Improving risk management:  from lame excuses to principled risk management.”  Available from the publisher or Amazon
