Job Description

The Pharmacokinetics, Dynamics, Metabolism, and Bioanalytics (PDMB) function of our Research & Development Division in West Point, Pennsylvania, is seeking a dynamic and collaborative scientist for the Drug Metabolism and Pharmacokinetics (DMPK) group. The Associate Principal Scientist will be a key contributor to multi-disciplinary drug development and discovery efforts providing an integrated understanding of DMPK properties, pharmacokinetics/pharmacodynamics (PK/PD), and drug interaction (DDI) risk of novel therapeutics.

The key responsibilities will be to work within teams of highly collaborative, cross-functional scientists to contribute to the discovery and clinical development of therapeutics across various modalities. The Associate Principal Scientist will guide the design and interpretation of in silico, in vitro, and in vivo analyses to support the discovery of therapeutics with the desired DMPK profile. They will assess DDI risk using static mechanistic and/or physiologically based pharmacokinetic (PBPK) models and guide clinical development teams on DDI strategy. They will author source reports and documents in support of regulatory filings. They will evaluate and predict potential program risks, while implementing appropriate strategies to address liabilities to ensure efficient program progression and decision making.
