Prof Karen Hudson-Edwards
Professor in Sustainable Mining
Karen joined the Environment & Sustainabilty Institute and Camborne School of Mines in October 2017. She researches the mechanisms and products of contaminant cycling in mine wastes, ground and surface water, contaminated land and dusts.
Karen's current research falls into three categories:
Characterisation of contaminant-bearing mine wastes, environmental minerals, waters, dusts
Development of remediation and mitigation schemes for mine wastes
Global biogeochemical and health impacts of mining
Editorial Board, Minerals
Fellow of the Geochemical Society
Fellow of the Mineralogical Society of Great Britain and Ireland
