Frequently asked questions
What sponsors, CROs and sites most often ask me before a mission starts.
What is the difference between a CRA and a study coordinator?
A CRA (Clinical Research Associate) works for the sponsor: she oversees sites and checks data quality. A study coordinator works within the investigator site, alongside the physician, to run the study day to day. I do both.
Where do you work?
I am based in Erquy, Brittany (France), close to a high-speed rail station and Rennes airport. I travel throughout France and abroad, and have monitored sites in France, Belgium and Tunisia.
How do you contract?
As a service provider through my company YDEALIS SARL, founded in 2005. You receive an invoice, with no payroll costs or long-term commitment. I can also work as a subcontractor for a CRO.
How quickly can you start?
Depending on availability, a mission can start within days. Send me your dates and I will reply within 2 business days.
Which documents can you provide for vendor qualification?
Company registration extract (Kbis), social security compliance certificate (URSSAF), professional liability insurance certificate, TRACE anti-bribery certification, CV and GCP training certificates.
Do you work in English?
Yes. I regularly work on international studies and write reports in English or French.
