MSc Biochemistry — University of Lyon

For more than 12 years, Lydie PARSUS has made the deliberate choice to explore the various roles that make up the clinical research ecosystem — from hospitals to CROs, from the field to coordination: Study Coordinator, Senior CRA, SSU & Contract Specialist, SSU Lead, Clinical Trial Lead, Clinical Oversight Manager. A journey across the European Union, the United Kingdom and North America, coordinating teams across several countries, from rare diseases to common conditions.
Her signature: end-to-end ownership of studies, from start-up to close-out, and a preventive vision of quality — having held every position in the chain, she knows where studies get stuck and anticipates issues before they impact timelines, data or patients.
Committed to passing on her experience, she mentors and trains junior CRAs — always with the same guiding principle, from the first negotiated contract to the last patient followed: improving the healthcare offered to people.
Why trust her
A natural facilitator role — aligning priorities, teams and timelines to keep every study on track
A dual strategic and operational view — understanding everyone's constraints, from the field to the sponsor, and making them work together
Communication tailored to each stakeholder: investigators, site teams, sponsors, vendors
Strong site relationships and risk anticipation, grounded in field experience
Proven adaptability — tools, regulatory constraints and shifting priorities
