NOTE: I've recently moved to the Meteorological Institute at the University of Munich, Germany. This website will move there soon as well.

Our group explores a range of dynamical phenomena in the coupled troposphere / stratosphere system. Examples include the dynamics that govern the temperature structure of the tropical tropopause layer, the dynamics of sudden stratospheric warmings, eddy(wave)-mean flow interactions and corresponding feedbacks, the stratospheric mean meridional circulation, transport processes in the upper troposphere / lower stratosphere.
