Learn more about the discoveries that paved the way for ExcellGene’s scientific foundation: White Papers and other publications, (co-) authored by F. M. Wurm and M.J. Wurm (De Jesus) over 3 decades.

White Papers are your gateway to stay tuned with challenges and trends facing the biomanufacturing industry, here from the scientific leaders and founders of ExcellGene, Professor Florian M. Wurm and Dr. Maria J. Wurm (AKA Maria De Jesus). Both are highly respected and frequently requested individuals (accumulated experience in the industry of 6 decades) for scientific and technological advice on the manufacture of recombinant biopharmaceuticals under large scale operation.
