Sr. Principal Scientist (Senior Director), Laboratory Lead – Molecular Pathology Full-time NEW

Molecular Pathology Laboratory Lead

Translational Molecular Biomarkers (TMB) develops, validates, and deploys biomarker assays across all therapeutic areas and stages of clinical development to enable pipeline decision-making. TMB laboratories translate biomarker strategies into fit-for-purpose clinical assays that inform target engagement, mechanism of action, patient selection, pharmacodynamic response, and clinical outcomes.

The Molecular Pathology Laboratory Lead is a senior scientific and people leader responsible for the strategic direction and operations of the Molecular Pathology laboratory. The successful candidate will lead a team of laboratory-based scientists developing, validating, transferring, and deploying tissue-based biomarker assays in support of our Company's clinical development pipeline.

The successful candidate will bring deep expertise in histology and tissue-based technologies, including immunohistochemistry, in situ hybridization, multiplex assays, and digital pathology. They will develop scientific talent and partner across our Company teams to deliver decision-enabling biomarker data for clinical programs.
