Academic Interests

I am currently working on several aspects of the large-scale interaction between the magnetosphere and the ionosphere. In particular, I am studying large-scale field-aligned currents during substorms using data from the AMPERE project as well as using data from the new SuperDARN mid-latitude chain to study subauroral polarization streams.
