About Volak S.

I’m an experienced Data Scientist, Predictive Modeler, and Actuarial Analyst. Previously, as an actuarial analyst, I worked with a Fortune 500 client to create a predictive model for their employee’s medical expenses. This model used GLMs as well as other algorithms appropriate for frequency and severity modeling. I am currently working with an Actuarial fellow to analyze a frequency severity model of Workers' Compensation data using XgBoost to predict future claims.
