Creating and Leading Analytic and AI Teams 

As Chief Scientific Officer and Sr. Vice President in the Consumer Solutions Group (CSG), a multibillion-dollar business at Optum, Ron led the Healthcare Analytics team which supports CSG's products and services. The Healthcare Analytics team had over 80 staff who supported the Optum business by using sophisticated machine learning statistical and econometric techniques.


Before that, Ron built and led the Healthcare Transformation Research and Reporting Center whose staff provided operational reporting for and evaluations of several disease management, specialty care, and wellness programs for large companies and insurers, including the largest UnitedHealth Group client, who provided over 5 billion dollars in annual revenue at the time.

IBM Watson Health provides artificial intelligence-based and other analytic, benchmarking, and consulting offerings to help providers, payers, life sciences firms, and government agencies improve health and healthcare and run their businesses better.  Ron led the Watson Health analytics research and development group of over 90 staff who used artificial intelligence, machine learning, and other tools to build, update, maintain, and visualize predictive models and algorithms for use in Watson Health offerings.
