Dr Walter got his education and PhD at the RWTH Aachen, Germany, and started his industrial career at Boehringer Ingelheim, Germany, in 1985. Here he became involved in the planning and establishing of a biotech facility, specifically responsible for establishing and leading the R&D Protein Chemistry within the Biopharmaceutical Division. For nearly 18 years he was responsible for Process Development Downstream Processing, including four different scientific groups engaged in the development of downstream processes at laboratory scale, scale up and the cGMP manufacture of clinical grade biopharmaceutical proteins for clinical phases I and II in a 2,000 L pilot plant. Other important areas of work were the development of methodologies and processes for viral clearance as well as the planning and performance of validation studies for viral clearance. Beside such process related activities, the groups worked on the design, development and implementation of technical equipment for downstream processing of biopharmaceutical proteins. Dr Walter participated in the scientific presentation of Boehringer Ingelheim by numerous scientific papers, presentations at international congresses and educational seminars as well as participation in the planning and organization of international congresses. In 2002 he accepted a management position at GE Healthcare, USA, as Unit VP Membrane Separation Sciences. He supported scientifically the establishment of new businesses such as Membrane Separations and Single-use Technology for GE Healthcare regarding industrial and regulatory requirements and applications in biopharmaceutical development and production processes. While operating Walter Biotech Consultancy since 2006, in 2009 to 2012 Dr Walter cooperated with Innobiologics, Malaysia. As acting SVP Biopharmaceutical Operations at Innobiologics he was responsible for three departments including Process Sciences, Biomanufacturing and Facility Engineering and successfully brought Innobiologics’ facility into cGMP operation. Since then, he has been deeply involved both in supervising production processes and in the planning and construction of biopharmaceutical facilities in China and Turkey. In October 2015 Dr Walter was admitted to the “1000 Foreign Talents” program of the Chinese Government. Dr Walter provides consulting and is specialized in biopharmaceutical development and manufacturing, including project planning, development and manufacturing management, process design downstream processing, including development, application and implementation of single-use technologies, drug safety, documentation and validation.
