Education

Course Directorship

- 2011, The Faculty of Actuarial Science and Insurance (FASI) seminar, Organizer

Subject/Academic Leadership

In August 2011 I became the organizer of the Faculty of Actuarial Science and Insurance (FASI) seminar.

Since then I initiated and with the support of the HoD and the Deputy Dean, we held meetings with various colleagues from FASI and Cass Business School working on improving the external visibility of our seminar among academics and practitioners, in particular within the actuarial profession. The concrete changes/improvements which were undertaken led to an increasing number of practitioners and academics from other universities attending our seminar series. The latter is also expected to facilitate the KT/Enterprise processes/projects with the profession.
