    • Demonstrated ability to integrate in vivo pharmacology with medicinal chemistry, DMPK, and biomarker strategy.
    • Experience advancing programs from discovery through development candidate nomination.
    • Strong CRO management experience, including protocol design, study oversight, data QC, troubleshooting, and vendor accountability.
