Academic Career and Research Areas

Prof. Kreupl (b. 1965) conducts research on applications for nano- and carbon-based materials, with a focus on carbon nanotubes, nanowires and graphene. These materials hold the potential to significantly improve the performance of components, sensors, interconnects and information and energy storage devices.

Prof. Kreupl studied physics at the University of Regensburg and earned his doctorate there in 1998 as recipient of a Siemens scholarship. He subsequently joined Siemens’ central research department as a development engineer. Beginning in 2000, he served as project manager for carbon nanotubes, nanowires and carbon materials at Infineon Corporate Research. From 2006 to 2009, he was responsible for evaluating new memory technologies at Qimonda. In 2009, he moved to SanDisk in Silicon Valley, California, where he oversaw the development of 3D memory technologies. In April 2011, he was awarded the Associate Professorship for Hybrid Electronic Systems at TUM. Prof. Kreupl is a member of the German Physical Society (DPG), the Material Research Society (MRS) and a Senior Member of the IEEE.
