Scientific expert
Pieter Van Wouwe received his Master’s degree and PhD in Bioscience Engineering at the University of Leuven in 2011. In March 2016, he started working at Nelson Labs as a project manager, initially mainly involved in scientific interpretations and the reporting of analytical results. Over the years, he has expanded his role and became responsible for designing pharma-related extractable and leachable studies for both packaging materials and process materials. More recently, he has broadened his expertise to include medical devices and combination devices. Providing support for extractables and leachables studies to both biopharmaceutical and medical device companies is one of his current focus points, while knowledge sharing - internally and externally - is also part of his current role at Nelson Labs.
