About the Series

The Evidence Mastery Book Series is designed as a complete professional curriculum for anyone working at the intersection of healthcare data and evidence generation. Each volume is self-contained and can be read independently, but together they form a structured progression from foundational literacy to advanced methodology.

Written by Dr Massoud Toussi, MD, PhD, MBA — VP of Real-World Evidence at United Biosource Corporation and a globally recognised expert with 20+ years across pharmaceutical, CRO, regulatory, and academic environments — the series reflects both rigorous scientific scholarship and the practical realities of everyday RWE work.
