Your Contributions (include, but are not limited to):
  • Develop custom reagents and assays on various platforms (e.g., ELISA, electrochemiluminescence, Gyros) for pharmacokinetic and/or immunogenicity assessments

  • Perform sample analysis to support bioanalysis efforts for non-regulated and regulated preclinical studies, including pharmacokinetics, pharmacodynamics, immunogenicity, and biological activity

  • Lead the development and qualification of ADA assays (e.g. bridging electrochemiluminescence) to assess immunogenicity in biologic programs

  • Work collaboratively with internal stakeholders to support CRO selection and oversee the transfer of internal assays to support regulated preclinical studies

  • Lead troubleshooting efforts for both bioanalytical internal methods as well as methods at CROs to ensure data quality

  • Effectively communicate results to internal/external teams in presentations and internally authored reports
