Research Interests

Metallic raw materials are essential for high-tech applications needed for a successful transition towards a greener future. Due to the scarcity of many base and critical elements in Earth´s crust it is increasingly difficult to find new, economic-relevant ore deposits. As the magmatic-hydrothermal processes which favour the enrichment of certain elements remain not fully understood, fundamental research on metal mobility, transport, and precipitation is indispensable to secure the future supply of metallic raw materials.

My research focuses on subduction-related submarine and subaerial magmatic-hydrothermal systems such as “black smoker” vents and porphyry-epithermal deposits. I combine statistical, experimental approaches, and high-resolution in-situ trace element and isotopic techniques on natural samples to understand the enrichment of critical metals in ore-forming systems.
