About
My journey in clinical research
I have been working in clinical research for 7 years. I started as a Clinical Research Associate (CRA), then grew into the roles of Senior and then Lead Clinical Research Associate, monitoring phase I to IV, notably in oncology, haematology and vaccines studies for CROs, pharmaceutical companies, biotechs and academic sponsors.
This experience taught me what matters in the field: a relationship of trust with investigators, reliable data, and risks anticipated before they become deviations. Today, I put this know-how at the service of your projects, in full independence.

FAQ
Frequently asked questions.
The essentials on working with a freelance CRA.
What is a freelance CRA?
A freelance CRA (Clinical Research Associate) is an independent professional who handles the monitoring and operational follow-up of clinical trials. They perform the same duties as an employed CRA — site visits, data verification, compliance follow-up — but work on a service basis, for a defined assignment or period, with no relationship of subordination.
Why work with a freelance CRA?
Working with a freelance CRA lets you quickly align resources with real activity: reinforcement during a peak, temporary cover, a one-off monitoring need, or field expertise for a first trial. Independence brings flexibility, responsiveness and a single point of contact, without permanently adding to your structure.
How much does a freelance CRA cost?
A freelance CRA usually charges a daily rate. It depends on several factors: seniority and specialisation, the nature and duration of the assignment, therapeutic areas, geographic zones and the volume of visits. The freelance model avoids the fixed costs of hiring and scales to the real need. Feel free to contact me for a discussion tailored to your project.
