Pierrick Fournier is a researcher at the CICESE (Centro de Investigación Científica y de Educación Superior de Ensenada, México) where his group is studying the interactions between cancer cells and normal cells within the tumor microenvironment, especially in bone metastases. He received his Ph.D. in 2005, from the Université Claude Bernard (Lyon, France) where he studied the properties of bisphosphonates, a family of anti-resorptive drugs, on cancer cells and angiogenesis in vitro and in vivo, under the direction of Philippe Clézardin, Ph.D. (INSERM). He joined then the laboratory of Theresa Guise, M.D. who mentored him throughout his postdoctoral training, at the University of Virginia (Charlottesville, USA), first, and then at Indiana University (Indianapolis, USA) where he became Assistant Research Professor in 2009. During this time, Pierrick's research focused on the role of TGF-ß and TGF-ß-regulated genes in the development of bone metastases. He also developed an interest in the field of osteoimmunology and how T cells could indirectly contribute to bone metastases when inducing bone resorption. In 2014, Pierrick was recruited by the CICESE to lead his research group and pursue studying cancer and bone metastases to identify new therapeutic targets and develop new treatments.
