My primary scientific expertise is in Birkeland currents. I am internationally recognised for my research into Birkeland currents with the AMPERE dataset, having contributed a review chapter to an AGU monograph and been invited to speak on the topic internationally, including at the AGU Fall Meeting 2019. Perhaps most notably, I discovered the interhemispheric asymmetry in Birkeland currents in my 2016 paper.

Alongside this, I have expertise in Cluster data. I used this dataset to examine the energy budgets of substorms and showed that during substorms, magnetic energy was stored and released sooner when the spacecraft was closer to Earth, consistent with the "inside out" substorm model. I also used Cluster data to survey hot plasma in the magnetotail lobes, statistically addressing open questions about this plasma for the first time. I have coauthored papers on both topics, alongside papers using MMS data to examine flux transfer events.
