Prof. Dr. Uwe Iben
Chief Expert Applied Mathematics
"Every science needs mathematics, mathematics does not." – Jacob Bernoulli
Chief Expert Applied Mathematics; until 03/2020: Head of Research and Technology Office Russia and chief expert for multi-phase flow and cavitation. Received PhD and MS degree in the Department of Numerical Mathematics at the Technical University of Dresden, including a 6-month course of study at Moscow State University. In addition to this, I received a PhD in process engineering from Otto-von-Guericke University in Magdeburg on the field of modeling of cavitation phenomena. Research interests include computational fluid dynamics of two-phase flow, modeling of phase transition, hydraulic systems, real gas flow, numerical methods for Euler and Navier-Stokes equations, and AI methods for numerical methods for differential equations.

Interview with Prof. Dr. Uwe Iben
Chief Expert Applied Mathematics
Please tell us what fascinates you most about research.
“Every science needs mathematics, but mathematics needs none.” (J.I. Bernoulli; 1655-1705) Research is curiosity, passion and perseverance in an effort to discover new things as well as develop existing ones. It means questioning what already exists and searching for alternatives. The simplest solutions are often the smartest ones. But research also has a lot to do with entrepreneurial spirit as good products can only evolve from well-understood interrelationships.
What makes research done at Bosch so special?
At Bosch, we merge basic research and industrial research. The goal is to develop products which inspire our customers while using resources as economically as possible in the process. I am most fascinated by developing and implementing ideas.
What research topics are you currently working on at Bosch?
I have researched on topics in the areas of flow mechanics and thermodynamics (cavitation) and, as part of a dedicated team, have drawn up simulative and experimental methods which are unique worldwide, enabling RB to manufacture hydraulic components offering a high degree of functionality and long service lives. I am currently researching mathematical methods in various areas, e.g. hybrid models, which are used in simulation models.
What are the biggest scientific challenges in your field of research?
After working as head of the research and technology offices of Bosch in Russia, I now work as Chief Expert Applied Mathematics in Renningen. We are preoccupied with many mathematical topics, e.g. hybrid models and analyzing multi-dimensional sensor signals in cooperation with international partners. The challenge here is represented by data processing, handling, and choosing suitable methods for extracting the right information from the signals.
How do the results of your research become part of solutions "Invented for life"?
Open and intensive contact with the various divisions has always been very important to me. Even the very best idea is of little use if it cannot be marketed. We work very closely with our project partners, testing prototypes and constantly exchanging ideas. We also include external partners in this process.
