I am working as Full Professor at SGH Warsaw School of Economics. I have PhD in Mathematics, Habilitation Degree in Economics and Professor title in Economics and Finance. I am an actuary with license no. 130 issued by the Polish Financial Supervision Authority, the Head of the Examination Committee for Actuaries at the Polish Financial Supervision Authority and a Board Member of the Polish Society of Actuaries. My scientific research includes different areas of actuarial mathematics with emphasis on stochastic modelling of financial risks and neural networks in insurance. I am Editor of ASTIN Bulletin – The Journal of International Actuarial Association.

Highlights:

28.06.2022 – My first PhD student Marcin Szatkowski defended his thesis

01.05.2022 – Together with Mathias Lindholm and Mario Wüthrich, we received Gauss Prize for the best paper published in EAJ

27.12.2021 – I received a nomination for Professor of Economics and Finance conferred by the President of the Republic of Poland
