Biography

Colin Maden began his career studying physics at ETH Zurich, graduating in 1998, and completing his PhD in 2003. He subsequently engaged in postdoctoral research focused on secondary ion mass spectrometry (SIMS) and accelerator mass spectrometry (AMS), particularly in developing a system known as SuperSIMS at the Laboratory of Ion Beam Physics at ETH Zurich. His work as a research scientist at the AMS Laboratory of Scottish Universities Environmental Research Centre in East Kilbride, UK, involved establishing the laboratory's routine operations and conducting analyses of various radioisotopes. He has also advised AMS scientists at the Centro Nacional de Aceleradores in Seville, Spain. Currently, he holds a senior scientist position and is involved in isotopic geochemistry and cosmochemistry, overseeing a range of analytical instruments and maintaining high standards in laboratory operations. His research includes developing a thermal ionisation cavity (TIC) source to improve ionisation efficiency in thermal ionisation mass spectrometry (TIMS), significantly enhancing analytical performance for rare earth elements.
