From SEB’s website:
In order for a person to be nominated for a President’s Medal, the nominee will need to be:
An independent researcher or scientist, in the early stage of their career, normally within 10 years* of being awarded their PhD
Must be demonstrating scientific leadership, have qualities which make them respected by their peers, and regarded as a creative and novel thinker.
A very hearty congratulations to Sonya on this wonderful achievement!
