As a research leader I build and steer world-wide science teams
As a mentor I support and encourage the next generation of research leaders
We have a responsibility as scientists to demonstrate the importance and relevance of our efforts to the public. Ideally, we inspire and make our audiences appreciate the importance of science.
In my public lectures and interviews I explain our discoveries to non-experts and I put my experience as a leader in basic research into the wider context of our society.
As speaker I build bridges between science and society
"As a student and postdoc in the Bonn VLBI group I had the unique opportunity to collaborate with outstanding scientists and to become an independent and successful scientist."
