Our research encompasses diverse projects and collaborations at the Ruhr-University Bochum and beyond. Find below information about the PI and the team.


Principal Investigator

Johannes Lederer

Johannes is Professor of Mathematical Statistics at the Ruhr-University Bochum. His educational training spans physics, mathematics, and statistics. After receiving a MSc in Physics, he started his Doctor of Sciences under the supervision of Sara van de Geer and Peter Bühlmann at ETH Zürich in December 2009 and completed the degree in December 2012. After that, he was a postdoctoral researcher hosted by Martin Wainwright at UC Berkeley, until he accepted the position as the Jacob Wolfowitz Visiting Assistant Professor in the Department of Statistical Science at Cornell University in August 2013. In September 2015, he joined the University of Washington as Tenure-Track Assistant Professor of Statistics and Adjunct Assistant Professor of Biostatistics at the University of Washington. In December 2017, Johannes was appointed in Bochum.

Johannes is currently also Visiting Professor at UC Louvain, Affiliate Faculty at the University of Washington, and Associate Editor of the Encyclopedia of Mathematics.
