Ksenia's primary focus is on predictive modeling and lifestyle-based analytics application to underwriting and disease management. This work includes consulting to healthcare plans on the use of lifestyle-based data to augment underwriting decisions and identify individuals for disease management and wellness initiatives. Lifestyle-based analytics play an especially strong role in risk selection in small/medium group market, and will integrate well with other risk selection approaches such as risk adjusters, Intelliscript and medical underwriting.

MARA utilizes Milliman's existing actuarial and clinical expertise and is perfectly suited for advanced applications of risk adjustment in health care budgeting, pricing, payment, stratifying risks and analytic reporting.
