Dr. James Siegenthaler is a research scientist at the Diamond Technologies division of Fraunhofer USA Center Midwest, housed on the campus of Michigan State University. He joined Fraunhofer USA after graduating with a PhD in analytical chemistry from the University of Arizona, focusing on instrument development and material characterization for electrochemical neurotransmitter measurement of dopamine in the brain. James has a diverse background including the study of spectroscopic techniques, chemical species in solution, quantifying pesticides in commercial products, and understanding the surface phenomenon of materials through AFM and SEM characterization. During his PhD, James developed a passion for additive manufacturing, designing and fabricating custom electrode holders and other instrument adapters for his research. At Fraunhofer USA, he leads two teams, focusing on metal additive manufacturing and diamond electrodes for electrochemical measurement. While managing the additive group, he leads a team to develop and optimize metal fused filament printing where they focus on vacuumless sintering to increase the accessibility of metal printing. He additionally works in collaboration with a multidisciplinary team as part of the Fraunhofer network to push additive manufacturing to the next limits.
