  • Experience supporting projects across multiple therapeutic areas and modalities (e.g. small molecules, peptides, biologics).

  • Experience handling radiolabeled materials, tissue preparations, and biological matrices.

  • Experience developing or implementing automation for in vitro ADME assays and leveraging informatics platforms for data collation/interpretation.

  • Prior experience in a researchdriven pharmaceutical or biotech environment.
