About TRA Modelling

The TRA Modelling is a contentual research alliance at the interface of applied mathematics, computer sciences, and application fields such as quantitative economics, life science/medicine, or geoscience. It is affiliated with the Cluster of Excellence Hausdorff Center for Mathematics (HCM) and further cooperates with researchers from the Clusters of Excellence ImmunoSensation2 and PhenoRob , the Interdisciplinary Research Units "Mathematics and Life Science", as well as the b-it (Bonn-Aachen International Center for Information Technology), the Fraunhofer Institute SCAI or the Max-Planck-Institute for Mathematics.

TRA Modelling is represented by the Spokespersons Prof. Dr. Alexander Effland (Applied Mathematics) and Prof. Dr. Jürgen Gall (Computer Science), who replaced the founding Speakers (Prof. Bovier and Prof. Röglin) at the General Assembly in February 2023. They are supported by the Steering Committee and the TRA Manager (see below for more information).

Inspired by tradition

The University of Bonn has a traditional strength in mathematics. The Hausdorff Center for Mathematics (HCM) with its integrated graduate school is the oldest cluster of excellence for mathematics in Germany and has made the University of Bonn one of the top mathematical research institutions worldwide. The exceptional standing of mathematics in Bonn is demonstrated by many high level awards, most notably two Fields Medals (“Nobel prize of mathematics”).

The Bonn University‘s Institute of Computer Science was one of the first of its kind in Germany. Hosting various ERC-Grant holders and one of the German Informatics Society’s “most influential minds from the German history of artificial intelligence (AI)”, Bonn is one of Germany’s top 10 computer science locations.

The Department of Economics of the University of Bonn is one of the leading economic research institutions in Europe and enjoys an excellent reputation worldwide. This is confirmed by international rankings as well as numerous highly ranked prizes and awards - notably the Nobel Prize for Economics in 1994.

Going beyond borders of disciplines

The TRA’s contentual self-concept is a deliberate "bottom-up culture" with a broad, open spectrum of inter- and transdisciplinary topics. The TRA Modelling was initially built around the core fields of mathematics and computer science applied to quantitative economics. Meanwhile, it developed towards further highly promising application fields such as life sciences/medicine, geodesy, and chemical engineering. In a participatory bottom-up process, the TRA sharpened its research profile and identified three (naturally overlapping) sub-schemes:

  • “Mathematics, Computational Biology & Medicine”
  • “Computer and Data Science for Economics”
  • “Data Analytics and Algorithm Engineering”

The main goals of TRA 1 Modelling are to strengthen inter- and transdisciplinary cooperation within mathematics, computer science, and its application areas as well as providing support to establish new cooperations and joint research projects. Furthermore, one of the overall goals of the TRA’s is to promote and support postdoctoral scientists and to provide opportunities for networking and academic exchange.
