Russell Osman

Russell was heavily involved in the initial development of Milliman’s Integrate® UK standard liability model, having led the team that tested its functionality. This effort covered a large heritage portfolio of UK with profits, non profit, and unit-linked business with a considerable range of features. This is Russell's go-to model for UK business and he has extensive experience in leading the customisation of the model for internal and external projects.

Russell led the development of and provides continuing senior technical input for the actuarial content of clients' Own Risk and Solvency Assessments, which examine the risks being run by an insurer and the capital it needs to support those risks now and in future years, covering various market and insurance risks and planned new business.

Russell has worked on both buy-side and sell-side M&A projects at various levels throughout his time with Milliman. For example, he has been directly involved in efforts ranging from challenging information provided by vendors to providing technical review to the modelling team.

Russell has led model review work for a unit-linked insurer, where required by its model validation cycle, using ad-hoc R scripts or directing the team in using independent Integrate models as necessary.

Russell is currently actuarial lead for an actuarial data transformation project for a large insurer using Milliman and Microsoft flagship cloud technologies, working in a multi-disciplinary team, including business analysts and data developers.
