## TL;DR

A Seattle-based nuclear medicine physician-scientist who ran the first human trial of a PET tracer that shows whether a tumour will respond to PARP-inhibitor drugs, and who now directs nuclear medicine and molecular imaging therapy at the Fred Hutchinson Cancer Center.

## Summary

Delphine Chen holds the Wil B. Nelp, MD Endowed Professorship in Nuclear Medicine at the University of Washington and directs Molecular Imaging and Therapy at Fred Hutchinson Cancer Center, a role she has held since 2019; from January 2026 she also became Clinical Research Director for Radiology at Fred Hutch. She was principal investigator on the first-in-human trial of 18F-fluorthanatrace (18F-FTT), a PET tracer for imaging PARP-1 expression to help predict response to PARP-inhibitor drugs, developed with a patent held by Washington University.

Her clinical practice covers the full range of oncologic PET and nuclear medicine therapies, and she has led trials using 68Ga-PSMA-11 PET to predict prostate cancer response to standard therapies. She currently serves SNMMI as President of the Center for Molecular Imaging, Innovation, and Translation.
