The International Max Planck Research School for Chemical and Molecular Biology (IMPRS-CMB) is a collaboration between the Max Planck Institute of Molecular Physiology and three universities, the Technical University Dortmund (TU Dortmund), the Ruhr University Bochum (RUB) and the University of Duisburg-Essen (DUE).

All four institutes are located in the Ruhr Metropolitan Area of Germany, an extremely vibrant and culturally interconnected region. The same spirit is reflected in the science of our program: research groups, with different and often complementary approaches, combine their efforts to study at the molecular level basic cell physiology.

Below you can find all the research groups that are part of IMPRS-CMB, in alphabetical order. You can also search groups by name, topic or technique.

Research Interest
My laboratory is trying to understand how the duplicated genome is passed accurately from one cell generation to the next. We are following two main questions:

1. How are kinetochores constructed to allow accurate chromosome segregation? We are performing a detailed functional analysis and biochemical reconstitution of the budding yeast kinetochore.

2. How are microtubules organized and regulated to move chromosomes? We are investigating molecular motors and other microtubule-associated proteins in order to understand how they function, how they are regulated and how they organize microtubules. 

In-vitro reconstitution and biochemical analysis of proteins and multi-protein complexes.
Yeast genetics and cell biological analysis of chromosome segregation in-vivo.
Advanced imaging techniques, such as total internal reflection fluorescence microscopy and reconstituted assays for dynamic microtubule growth.
