Jeremy Bloxham is a planetary scientist who carries out research into the origins of magnetic fields in the planets of our Solar System. His first major contribution was to use historical measurements of the direction of the Earth’s magnetic field to construct maps of the evolution of the field at the core–mantle boundary.

His work has led to a greater understanding of the geomagnetic dynamo and core dynamics. He is currently contributing to NASA’s Juno mission to Jupiter. This mission will provide a global set of observations of Jupiter’s magnetic and gravitational fields, amongst other observations.

Jeremy has served on the editorial boards of both the Journal of Geophysical Research and Geophysical Journal International. In 1994, he was awarded the Macelwane Medal of the American Geophysical Union, and in 2001 he received the Chapman Medal of the Royal Astronomical Society. He is an elected Fellow of a number of prestigious scientific societies.
