I lead the 14 member group (Particle Precipitation), bridging the interdisciplinary field of space physics and atmospheric science, with a focus on the effect of energetic particle precipitation (EEP) on the atmospheric system.

My research has given new quantitative estimates of the electron flux from measurements performed by the particle detector MEPED on board the NOAA/POES satellites. It has given the BCSS a leading role in the community working with EEP, and numerous papers assessing the chemical impact of EPP on the atmosphere. I have won several research grants both as a principal investigator and as a co-investigator. I have been a Fulbright fellow, and I am currently a Young Center of Advanced Study Fellow. I am leading and co-leading two international working groups.
