Distinguished Lecture Program

The European Association of Geochemistry started its Distinguished Lecture Program in 2011 and it currently focuses on Central and Eastern Europe. This program aims to introduce and motivate scientists and students located in under-represented regions of the world to emerging research areas in geochemistry.

The distinguished lecturer is selected each year based on a combination of outstanding research contributions to geochemistry and the ability to clearly communicate these contributions to a broad audience.

Distinguished Lecturer

Karen Hudson-Edwards_170Prof. Karen Hudson-Edwards, University of Exeter, UK

Karen Hudson-Edwards is based in the Environment & Sustainability Institute and the Camborne School of Mines at the University of Exeter, where she is a Professor of Sustainable Mining. Her research focuses on understanding the character and geochemical mobility of mine wastes, and on designing management and remediation schemes to lessen their impacts on ecosystem and human health. Over the past 25 years she has worked all over the globe, studying the aftermath of tailings dam failures, the geochemistry, mineralogy and microbiology of different types of mine wastes and the effectiveness of remediation and management schemes. Her work has been supported by the Natural Environment Research Council, Science and Technology Facilities Research Council, Royal Society, EU and industry. She is an Editor of the AGU journal GeoHealth, and Editor-in-Chief of the Environmental Mineralogy and Biogeochemistry section of the journal Minerals. She has contributed to sustainable mining public displays at the UK Science Museum and the Eden Project. Currently she supervises a research group of eight post-docs and PhD students working on a variety of projects, including bioleaching of Ni-Cu-Co ores, the characterisation of metal-organic pollutants for remediation of mining environments and the global implications of acid mine drainage.


  • Lecture 1: The What, Where, How and Why of Mine Tailings
  • Tailings are wastes comprising mixtures of crushed rock and processing fluids from mills, washeries, or concentrators that remain after the extraction of economic metals, minerals, mineral duels or coal from the mined resource. They contain potentially toxic metals and metalloids and can be very reactive, generating acidity or alkalinity and affecting ecosystem and human health. To understand their impacts we must ask the what, where, how and why questions.

  • Lecture 2: The Global Biogeochemical and Health Impacts of Mining
  • Mining is a vital part of the global economy, but unmanaged releases of mine wastes can affect the health of humans, ecosystems, water, soil and Earth surface environments such as rivers, estuaries, oceans and the atmosphere. New technological developments and multi-disciplinary collaborations are leading to new insights into the relationship between mining and the health of the Earth, and the effect of mining on global biogeochemical cycles.

  • Lecture 3: Environmental Minerals: Bacteria, Worms, Dusts, Toxins and the Human Body
  • Environmental minerals are naturally-occurring or anthropogenically-derived, inorganic or organic, often formed through biological processes, crystalline to very poorly crystalline and have fixed or variable compositions. They occur in virtually all Earth Surface environments, including the human body. Novel nano- to macro-scale technologies are allowing scientists to probe them in more detail than ever before.
