Prof. Dr. Christian Schachtner | Data Science | Research Excellence Award

Full Professor at Hochschule RheinMain, Germany

Prof. Dr. Christian Schachtner has made significant scholarly contributions through his monographs and editorial work in the fields of smart governance, smart cities, and digital transformation in the public sector. In 2025, he edited Smart Public Governance, a volume in the Kohlhammer Publishing series, scheduled for publication in the first quarter of 2026. He also co-edited, with M. Brunzel, the Handbook Smart Cities / Smart Regions, likewise forthcoming from Kohlhammer Publishing in early 2026. His edited book The European Smart City Movement  Case Studies from Around Europe, published by Springer in Chur, presents comprehensive insights into smart city practices across Europe. In the same year, he authored CDOs im öffentlichen Sektor – Perspektiven auf Chief Digital Officers und Strategien zur digitalen Transformation, published by Springer, which explores the evolving role of Chief Digital Officers in public administration. Collectively, these works highlight his expertise in digital governance, urban innovation, and strategic public-sector transformation.
