dr. A.H. Dijkstra (Arjan)

I am a geologist interested in the sustainability and security of the supply of critical raw materials, i.e., the rocks and minerals from which we get the chemical elements needed for the energy transition. My research focus is on rare earth elements (REE, e.g. neodymium), cobalt, lithium and indium. I study their distribution in the Earth, and the processes that form economic mineral deposits from which they can be extracted.

I have a background in igneous petrology, geochemistry, tectonics and structural geology, and have held academic positions in Plymouth (United Kingdom), Neuchâtel (Switzerland), Perth (Australia) and Leicester (UK). I have a doctorate from Utrecht University (The Netherlands).

I also have a keen interest in public engagement. A recent example of an outreach video  that I was involved with about the elemental composition of a smartphone is here (youtube)
