He has written over 200 papers, 6 book chapters, and 13 patents. His research focuses on the understanding and application of surface interactions of materials with gases. Since 1984, when he started his scientific career at the Institute of Materials Physics and Technology in Bucharest, he has focused on the understanding of phenomena taking place at the surface of metal oxides operated in realistic conditions for gas sensing applications. He has also explored different technologies for devising better gas sensing materials and innovative sensors. He has invented the hybrid microsensor production technology based on the combination of sensing layers based on pre-processed powders and micromachined Si transducers. In 2001 he co-founded Advancing Sensing Devices (ASD) which merged with Applied Sensors and established itself as a leading European company in the field of gas sensor technology and application developments. In 2000 he was a locum professor at the Applied Physics Department of the University GieBen. Prof. Schierbaum has been and is actively involved in large national projects dealing with sensor development and EC funded projects. He is a member of the Deutsche Physikalische Gesellschaft (DPG), German Bunsen Society for Physical Chemistry (DBG), German Society for Materials Science, German Association of University Professors and Lecturers, Association of Electrochemistry Research Institutions, and many others.
