Pierre completed his PhD in 2005 at the University of Bordeaux-1 (France) with a speciality in polymer chemistry with Prof Henri Cramail and Dr Eric Cloutet. His research involved studies of core-shell polyurethane particles in organic solvents and supercritical carbon dioxide (including step growth and controlled radical polymerisation (ATRP), colloidal science, GPC, NMR, DLS, TEM/SEM. Pierre moved to the University of Sheffield (Prof Tony Ryan) for a 4 year, EPSRC/industry collaboration studying the complex flow of polymer blends ('05). He moved to the University of Liverpool ('08), (Dr Jon Weaver and Dr Dave Adams) to study amphiphilic stimuli-responsive branched copolymers as stable nanoparticles. He returned to the University of Sheffield (Prof Steve Armes) as a Reckitt Benckiser/Yorkshire Forward funded PDRA ('10) studying diblock copolymer vesicles for using aqueous dispersion RAFT polymerisation.

In November 2011, he joined the Rannard group (Liverpool) to work alongside two PhD students and the Owen group in the Department of Molecular and Clinical Pharmacology. The work studied branched polymers and their potential for novel HIV/AIDS therapies.

After becoming a Research Coordinator in 2020, Pierre facilitated the delivery of numerous polymer programmes and PhDs, including the co-invention of Transfer-dominated Branching Radical Telomerisation (TBRT) with Savannah Cassin and Steve, leading to the creation of Polymer Mimetics Ltd after licensing to Scott Bader. Pierre left the group in 2022 to move to Germany with his family. He maintains an honorary Research Fellowship at Liverpool.
