His academic background spans insurance accounting, Solvency II, reinsurance, and risk management. He has more than 15 years of experience in the insurance and reinsurance industry.
Luxembourg is one of the two largest captive domiciles in Europe by entity count. The jurisdiction had 197 captives in 2024, tied with Guernsey, according to AM Best data. The domicile has been an established hub for reinsurance captive structures serving European parent companies.
