My background in earth sciences and solid-sate physics is also my core strength: strong analytical skills, with the ability to cope with complex details and interdependencies while keeping the big picture in view, both regarding science and economics.During my 20 years as Managing Director of the Gübelin Gem Lab, I have transformed the lab from a group of individual experts into a team of specialists working along standardised procedures, using the most sophisticated analytical methods (incl. Laser Ablation - ICMPS) and deploying custom-built algorithms / expert systems & software for the most consistent evaluation of the collected analytical data. These achievement were the prerequisite allowing the expansion of our lab, with new and fast-growing permanent lab facilities in Hong Kong and New York. The personal achievement that gives me the most pride and fulfilment is the development of a range of truly disruptive technologies, including the Emerald Paternity Test (using physical anchors based on DNA-based nano-sized tracers) and the ProvenanceProof Blockchain (in partnership with #Everledger) for use in gemstone materials, giving a completely new level of traceability and hence transparency into the gemstone business. Our Provenance Proof technologies triggered a new era for our lab and is a major game-changer for the gemstone industry. See www.provenanceproof.com for details.I continue building new technologies (we are currently building a software deploying deep learning / AI logic in cooperation with #CSEM, supported by #Innosuisse), as well as sharing - by writing and presenting - our R&D achievements with the trade and the public. This sharing is one major and very satisfying part of my work.
