About Me

My name is David Ernst Styn, and I am a geochemist specializing in critical metals such as germanium, gallium, and rare earth elements (REY). Although I entered geosciences by coincidence rather than long-term planning, it quickly developed into a clear professional path. The combination of scientific rigor, analytical work, and global relevance in resource research continues to motivate my career.

I completed my bachelor’s degree at Ruhr University Bochum, where I gained broad interdisciplinary training across the geosciences. This foundation still shapes my ability to connect geological, chemical, and environmental processes. I then pursued my master’s degree at TU Clausthal, a university with a strong mining and raw materials profile. There, I focused on natural resource geosciences and mineral ore deposits, and my master’s thesis examined cobalt and nickel distribution in ferromanganese crusts.

In 2017, I joined Jacobs University Bremen as a researcher and began my PhD in 2019. My doctoral work centered on the geochemical behavior of the critical metal pairs Ga–Al and Ge–Si, combining analytical innovation with strategic resource relevance. I completed my PhD in 2023. Over these years, I performed extensive trace metal analyses, working with samples more than two billion years old, and gained hands-on expertise across multiple laboratory environments. I also participated in international field campaigns that provided access to locations rarely visited outside scientific research.

Together, these experiences have shaped me into a researcher who combines rigorous analytical skills with a practical understanding of global resource challenges, especially those related to the supply and sustainability of critical metals.
