About Mehdi
Medical doctor and biostatistician (MD, MSc) with 10+ years supporting clinical development, regulatory submissions, and scientific content creation for pharmaceutical, MedTech, and IVD companies.
What sets me apart: I don't just write documentation, I help define the clinical strategy behind it. Endpoint selection, success criteria, benchmarking against state of the art. My dual MD + biostatistics background lets me solve these upstream questions, then carry through to the final deliverable. One consultant instead of three.
What I deliver:
→ Clinical study design : endpoint definition, protocols (CIP), SAPs, sample size calculations, benchmarking against predicates
→ Regulatory documentation : CER, PER, CIR, literature reviews, meta-analyses, FDA, CE, MDR, IVDR submissions
→ Health authority interactions : FDA Pre-Submission, Notified Body responses
→ Biostatistics : study design, sample size, SAPs, agreement studies, equivalence testing, method comparison, survival analysis, diagnostic accuracy, imaging endpoints
→ SaMD/AI validation : diagnostic accuracy evaluation, algorithm benchmarking, 510(k) and CE support
Clients: Essilor Instruments (ophthalmic devices, 6+ product lines), Ligence & AIATELLA (cardiovascular AI SaMD : FDA, CE, MHRA), RetInSight/Topcon (retinal AI), OXcan (liquid biopsy IVD), ZOĪ (scientific publication), AP-HP (evidence synthesis).
Previously at Median Technologies (imaging CRO), point of contact for Roche, AstraZeneca, Merck, Amgen. Clinical Lead at Canon Medical Systems : multiple CE and FDA clearances.
