Martin Janssen is a private lecturer at the Institute of Theoretical Physics at the University of Cologne and a high school teacher at the Friedrich-Wilhelm-Gymnasium in Cologne. He gained his doctorate in 1990 in Cologne for his work on magneto transport and multifractality in the context of the quantum Hall effect and his venia legendi ...

He held a DFG Postdoctoral Fellowship at Oxford University in 1993 and a Minerva Postdoctoral Fellowship at Haifa University in 1995. He has been a member of academic staff at the University of Cologne from 1992 to 1998 and at Bochum University from 1998 to 2001. After working as an environmental physicist from 2001 to 2011 he became a high school teacher in physics and mathematics. Since 2001 he gives lectures at the University of Cologne on Theoretical Physics with emphasis on dynamics of stochastic processes. He has co-written a book on the integer quantum Hall effect and written a book on fluctuations and localization in mesoscopic electron systems. Show Less
