The British Geophysical Association is delighted to announce that the Bullerwell Lecturer for 2026 will be Dr. Ualisson Donardelli Bellon from the University of Edinburgh.

Dr Ualisson Donardelli Bellon is a Postdoctoral Research Associate in Mineral Magnetism at the School of GeoSciences, University of Edinburgh. His research investigates magnetic phenomena at the nanoscale to better understand the stability and evolution of planetary magnetic fields, combining micromagnetic modelling with advanced imaging and chemical analyses, including synchrotron-based techniques.

Dr Bellon holds a PhD in Geophysics (University of São Paulo, 2024), an MSc in Geophysics (University of São Paulo, 2021), and a BSc in Geology (Federal University of Espírito Santo, 2018). His doctoral research focused on studying vortex-state magnetic minerals in carbonate rocks through magnetic mineralogy, synchrotron imaging, and numerical modelling. His academic background spans experimental and computational approaches to mineral magnetism, with applications in palaeomagnetism and planetary evolution.

Dr. Bellon has also won a prize for the Best Geosciences Thesis in Brazil in 2025. He has published in leading journals such as Geophysical Research Letters, Journal of Geophysical Research: Solid Earth, Communications Earth & Environment, and Proceedings at National Academy of Sciences (PNAS).  Further information, and publication references, are available at: https://www.research.ed.ac.uk/en/persons/ualisson-donardelli-bellon/

The title of his Bullerwell lecture is: 

“From microscopic minerals to planetary magnetic fields” 

As part of the award, The British Geophysical Association has funds to cover the associated expenses for a number of these lectures.
