Dr Caitriona Jackman 

Senior Tutor, Physics and Astronomy

Academic Lead, SPace Research and Innovation Network for Technology (SPRINT)

Dr. Jackman is an Associate Professor of Space Physics. She holds an STFC Ernest Rutherford Fellowship to study planetary and stellar magnetospheres.

Dr. Jackman obtained a BSc in Applied Physics from the University of Limerick in 2003 and a PhD in Planetary Physics from the University of Leicester in 2006. She has held research positions at Imperial College London, and two consecutive fellowships (Leverhulme Trust and Royal Astronomical Society) at University College London. She moved to Southampton in 2013.

Research

Research interests

Her research interests include large-scale structure of giant planet magnetospheres, auroral physics, the energy budget of Earth's magnetosphere (with implications for ground-based technology and services), machine learning and complexity science. She is also very active in outreach and public engagement.
