Starting 1 January 2022, InterAct serves as a project frame for a range of research and education activities of high market proximity in actuarial mathematics and related fields. The frame is the result of an agreement of extensive collaboration between the Department of Mathematical Sciences and currently seven of the country's insurance companies and pension funds. The agreement marks a historic initiative to promote education and research in actuarial science in Denmark.
You can read more about our vision and research below. In the article Matematikken bag bedre forsikringer til en mere fair pris, published 2023 in Aktuel Naturvidenskab (in Danish), the associated faculty also unfold some of the research questions that are central to the project frame.
The project frame InterAct is an ambitious, strategic, and long-term strengthening of the collaboration concerning research and education in actuarial mathematics between the Danish insurance and pension sector and the University of Copenhagen. InterAct elevates the University of Copenhagen's research and education activities in actuarial mathematics with and towards the industry by creating significant increases in volume, variation, and practical relevance to the benefit of all parties.
InterAct forms the foundation for intensified research and development of actuarial courses within a number of areas that influence the evolution of the insurance and pension sector – now and in the years to come. This includes
- data science, machine learning, and artificial intelligence
- sustainability and decision making under sustainability risk
- prevention and containment as a form of risk mitigation
- emerging risks such as climate risk, cyber risk, and pandemic risk.
The studies take balanced account of applications to both life and non-life insurance; for instance, multiple of the studies build bridges between these two areas of application thematically as well as methodologically.
The University of Copenhagen receives knowledge and ideas in the form of active participation and influence from the insurance and pension sector – and resources in the form of external funding therefrom. The University of Copenhagen also provides to the project frame knowledge, ideas, and resources. The outcome is research in topics derived directly from problems of high market proximity, additional and stronger actuarial mathematicians on both the master's and PhD level, and continuing and professional education targeted the Industrial Partners.
The Steering Committee of InterAct continuously assesses the frame's progress with respect to the purpose of the project frame. It consists of one representative from each of the Industrial Partners and three representatives from the Department of Mathematical Sciences (MATH). Currently, the Steering Committee is composed of the following members:
- Mogens Steffensen, MATH
- Tinne Hoff Kjeldsen, MATH
- Christian Furrer, MATH
- Kristian Buchardt, AP Pension
- Bo Søndergaard, Danica
- Rikke Sylow Francis, Industriens Pension
- Line Dahlbæk, PensionDanmark
- Bjørn Lunding Sandqvist, Tryg
- Magnus Tor Ry Warburg Hessler, Velliv
- Anders Damgaard, PFA.
The Steering Committee has set up an advisory body, the so-called Temaudvalg, which is tasked with discussing and proposing project topics. Besides one representative from each of the Industrial Partners, it consists of up to five representatives from the Department of Mathematical Sciences and two representatives from Den Danske Aktuarforening. Currently, it comprises the following members:
- Mogens Steffensen, MATH
- Christian Furrer, MATH
- Mogens Bladt, MATH
- Munir Hiabu, MATH
- Kristian Buchardt, AP Pension
- Anders Druedahl, Danica
- Jonas Gylden, Industriens Pension
- Samuel Achord, PensionDanmark
- Bjørn Lunding Sandqvist, Tryg
- Magnus Tor Ry Warburg Hessler, Velliv
- Niklas Lindholm, PFA
- Lars Sommer Hansen, Den Danske Aktuarforening
- Jesper Sonne, Den Danske Aktuarforening.
