He has published more than 70 articles in international journals in fields ranging from biochemistry and molecular biology to cell biology. Jean brings to Da Volterra his wide expertise for conducting R&D programs, understanding finely diseases as wel as drugs mode of action, developing adequate in vitro assays to model in vivo situa- tions, optimizing both chemical and molecular analytical tools and biomarkers, and establishing in vivo studies. Da Volterra's vision si to be a trusted and acknowledged leader of drug and medical device development in the microbiome field. His mission is to discover and develop up-to-market safe and novel therapeutic options, preserving patients' microbiome to prevent and cure life-threatening diseases.
