I attended the Human Microtracer Studies Symposium in Leiden (April 21st, 2022) and found it exceptionally valuable.

The symposium featured high-quality presentations and brought together leading experts in the field. The networking opportunities were outstanding – connecting with fellow specialists provided insights that extended well beyond the formal sessions.

Holger Scheible

PhD, Head of Biotransformation within NCE DMPK at Merck Healthcare KGaA
