Curriculum vitae:

Dr. Winfried Michels, born 1952 in Warburg-Scherfede in Germany, studied chemistry at the University of Paderborn, where he completed his studies with a diploma in 1981. In 1983 he obtained a doctorate and the qualification Dr. rerum naturum with a dissertation in the field of biochemistry. He has been employed at Miele from 1985 to 2015 in the Professional product division and was responsible for the development of solutions to various problems in the field of applications technology, with the focus on machine-based cleaning and disinfection methods. A remarkable number of patents have been implemented based on his inventions. The changeover from routine used of the so called BGA-process to the Vario-process or the use of protein analytical method for assessment of surgical instrument cleaning has been initiated by him.

He is now running an own testing laboratory and working as a consultant for some companies. His focus is still on cleaning of medical devices with ultrasound and washer/disinfectors assessed by analytical methods (OPS, BCE). New methods like AHD575 for haemoglobin and TOC are under investigation.

He is a member of several chemical (DGCH) and hygienic societies (DGKH, DGSV, ÖGSV) and working groups (AKI, guideline groups) as well as the standardisation groups DIN NA Med D09 (deputy convenor), CEN/TC 102 WG 8 (since 1995) and the ISO/TC 198 WG 13. He published a notable number of scientific papers on instrument reprocessing.
