Building Blocks of Matter and Fundamental Interactions (TRA Matter)

© Bialek/Uni Bonn

The formation of complex structures based on the fundamental building blocks of matter and their interactions is investigated from subnuclear and subatomic over atomic, molecular, bio-molecular to terrestrial and astronomical length scales, increasing the knowledge of mankind on the fundamentals of nature. Sophisticated and highly visible experiments are done in the synthetic, analytical, spectroscopy, optics and detector laboratories at various Institutes at the University of Bonn, at its electron accelerator ELSA, and colliders worldwide as well as at observatories on the ground and in space. These experiments are complemented by world-leading theoretical calculations which in part also surpass the boundaries presently accessible by experiment. This research is highly recognized internationally and is supported within several coordinated research programs.

Scientific networks of chemists, physicists, biologists, pharmacists, geologists, and many more address highly challenging questions by exploring nature at all relevant distance scales. Even though the investigations are largely driven by curiosity to understand the inner workings of nature, they also lead to numerous spin-offs for technology and society such as detector technologies, first steps toward quantum technology, image analysis and rational molecular design.

Intensified collaboration between the various research groups crossing the boundaries of the different fields of science benefits not only the research but also the education of our students. Strong connections not only to large scale research infrastructures worldwide, such as CERN1, FAIR2, KEK3, BESSY, ALMA4, eROSITA5 , Euclid6, and Athena, but also its local infrastructure and the connections to the institutions of the Max-Planck Society (MPIfR7, MPI CEC8, caesar9), the ABC/J Geoverbund10 and the Forschungszentrum Jülich11 make Bonn a unique location for fundamental research.

Two recently appointed Argelander professors initiate exciting Biohybrid Research at the University of Bonn


Combining artificially created building blocks with natural ones - that is the goal of two new assistant professors at the University of Bonn. Biophysicist Dr. Alena Khmelinskaia and biophysical chemist Dr. Patrycja Kielb work at the interfaces of different disciplines and hold so-called Argelander professorships, two new posts created at the university with funds from the Excellence program. Alena Khmelinskaia and Patrycja Kielb are now building a bridge between chemistry, physics, and life sciences in the TRA "Building Blocks of Matter and Fundamental Interactions". Their work is relevant for the development of sustainable technologies in modern societies, for example, in medicine or energy research.

First networking workshop with members of the academic staff in the heart of the Siebengebirge


Members of the Transdisciplinary Research Area "Building Blocks of Matter and Fundamental Interactions (TRA Matter) chose an extraordinary place for networking. On a sunny day and with posters printed on canvas, the hike started to the viewpoint “Hülle”, which is located above Oberdollendorf (in the heart of the Siebengebirge). Besides getting to know each other personally, the scientific exchange between physicists and chemists researching at the University of Bonn was in the foreground. A successful day out in nature.
