Alois Gisler

Alois Gisler had studied mathematics at ETH in Zürich and he had written his PhD-thesis with Prof. Hans Bühlmann.

After his studies he had been working for nearly 30 years as a full practicing actuary at AXA-Winterthur Insurance Company. He has a broad practical experience in nearly all actuarial fields of a direct insurer, in pricing, reserving, reporting, solvency, securitisation, etc. He had been the head of actuarial non-life and also the appointed actuary for AXA-Winterthur Insurance Company and for Winterthur-ARAG, legal-protection Insurance-Company. In his function as head of actuarial non-life, he was responsible for pricing, reserving, actuarial reporting and other actuarial services. As AXA-Winterthur is the market leader non-life in Switzerland, Alois Gisler was engaged in all major actuarial topics and developments in the Swiss market-place. In particular he was heavily involved in the development of the Swiss Solvency Test, where the model for the insurance risk non-life bears his signature.

Besides being a full practising actuary Alois Gisler has always kept close contact to actuarial science. He had been coeditor of the ASTIN-Bulletin during 10 years. Since 1992 he has been a lecturer in actuarial science and since 2002 a professor at ETH. He has written many articles, mainly in credibility theory.

At mid 2009 Prof. Alois Gisler went on pension at AXA-Winterthur in order to have more time for research and lecturing at ETH.
