Associate Scientist In Vivo

As an Associate Scientist II I'm part of a team of biologists of the Janssen Oncology department. My job consists of supporting the Oncology in vivo group efforts in the characterization and development of small molecules and biologics including those that function as immune modulators for the treatment of cancer. I'm responsible for contributing to the ex vivo and in vivo studies for programs across the different stages of pre-clinical drug discovery.

Other responsibilities include the design and execution of in vivo studies for the validation and characterization of targets or therapeutic agents in the area of oncology and tumor immunology. Specifically, to establish and perform in vivo model development, target inhibition, efficacy, mechanism of action, and pharmacokinetic/pharmacodynamics (PK/PD) biomarker studies, and will evaluate the influence of dose, schedule, and therapeutic combinations in various cancer models.
