Gaelle Saint-Hilary works in statistics for the pharmaceutical industry since 2006. She is currently completing a PhD on “Quantitative Decision-Making in Drug Development”, sponsored by Servier, at the Polytechnic University of Turin (Italy). Before that, she worked as biostatistician in the industry, first at Servier for 5 years and then at Novartis Oncology for 4 years. She was responsible for the clinical development and the licensing of medicinal products in neuropsychiatry and leukemia, and her main scientific interests were benefit-risk assessment, network meta-analyses, multiple test procedures, simulation models of time-to-event data and survival analysis in presence of intercurrent events. The development and the promotion of quantitative methods for drug benefit-risk assessments is one of the major topics she considers during her PhD, with the final goal of enhancing decision-making throughout the drug life-cycle. 
Graduated in 2011, Stéphanie Cadour works as a biostatistician at Servier (France) since then. She was initially responsible for the statistical aspects of phase II and III clinical studies conducted in the therapeutic areas of neuropsychiatry and diabetes. She is now working on early phase studies in the field of oncology. In parallel of these activities, Stephanie developed skills on meta-analyses as well as on quantitative approaches for benefit-risk assessment on which she has been working on since 2011.PSI Book Club: Change: How organisations achieve hard-to-imagine results in uncertain and volatile times
Organizations have to adapt to the transforming landscape of our industry to ensure they continue to be successful in the future. Many of us are feeling the impact of organizational change. By reading John P Kotter’s book we can understand about organizational change and learn how to thrive, rather than just survive, through change. Change, by John P Kotter (and his team), is a summary of all that he has learned over his decades of research and leading change. His book describes why many current approaches to change are inadequate and explains why new solutions need to give people a voice and a role in a new, change-embracing organization. Develop your understanding of organisational change and become empowered to be part of your organisation’s change, by reading Change by John P Kotter and joining the Sept-Dec 2025 book club. You will be invited to join facilitated discussions of the concepts and ideas and apply knowledge from the book in-between sessions.
